Cobb Tuning Mazdaspeed 3 Short Throw Shifter With us finally entering the summer months, we eagerly wait for the latest performance parts to drop down into our little hands for our beloved Mazdaspeed 3's. Cobb Tuning has released their new double adjustable, short throw shifter. Although we don't consider this a performance part in a manner that makes power, it certainly provides performance enhancements in the way you drive your car, by increasing the performance of the transmission. Face it, one of the least favorable components in these cars is the shifter mechanism. Its sloppy, tall and the aftermarket really hasn't addressed this problem entirely. There's one other short throw shifter out there that sort of fits the bill, but it works best when used with new solid shifter base bushings. Many of us have these bushings and they seem to improve shifting performance, but the problem still exist. You simply don't feel confident ripping gears on this little car, especially when power shifting through the gears. So, Cobb worked up a little magic for the Mazdaspeed 3 by building us an entirely different shifter.What does double adjustable mean? Cobb designed these shifters back when they were strictly tuning Subaru's. You could reduce the throw ratio when shifting gears by anywhere from 10% up to 30%. You could also adjust the height of your shifter. With many STS's on the market for various cars, alot of them suffer the same syndrome, the shifter sits to low. Cobb was able to defeat this problem by creating, the double adjustable short throw shifter. Prior to doing the work up on this review, a friend of mine who owns a Mazdaspeed 3 wanted me to help him install his TWM Perf Short Throw Shifter for him. I wanted to see how this shifter felt in the car when rowing through the gears. So, 65 minutes later, i got my wish. The first problem i realized when i put his car back together after the install was how low his shifter sat. Im one of those persons who doesn't like my shifter to sit extremely low. It took a bit to get used to, but after a few miles, i felt more comfortable banging through the gears. It was much improved over the stock shifter, but it still needed those shifter base bushings installed, which he did not order. These bushings are installed on my car and helped remove some of the unwanted slop out of the stock setup. Knowing that Cobb had shipped me out a DA-STS for us to review, i contacted TWM Perf and asked them if they wanted to do a head to head with the Cobb unit. I was contacted roughly a week later and they seemed very interested in wanting to toss us a shifter setup to review alongside the Cobb. Unfortunately, when final details were exchanged, the communication between myself and them, disappeared. So, we cant bring you a head to head, BUT since i did install one a few days ago for a friend, i can give you a pretty good comparison between the two during this review. So, let's move on to the construction of Cobb's DA-STS, shall we? The Cobb unit is probably one of the most attractive shifters I've personally installed. Its such a shame to see something this attractive, covered by a shift boot. Its constructed out of Billet aluminum with a billet steel shaft and comes anodized blue with a nice engraved Cobb logo. The first section of the billet body is the adjustable throw mechanism located on the lower part of the shifter. By moving the ball from it's lowest point, to the highest point on the unit, you can reduce your throws from as small as 10%,15%, to a medium of 20%, and a max of 25% or 30%. The second section of the billet body is the shaft height adjustment mechanism. This controls how low or high you want your shift knob to sit. It has 2 stainless 3mm allen bolts that secures the knob shaft to the shifter itself. This allows greater adjustment for height, without disturbing the selected reduction of throw you want. TWM's approach is much different. They reduced the height of their shifter by 1.75" based off their own preferences. Not everyone will feel comfortable with such a low sitting shifter. They do however, offer the same reduction of 30% from shift throws, but that's it. The first thing you notice with larger reduction of throws, is more notchiness during shifting. If you are annoyed by this, the Cobb unit gives you the option to tune it out by changing the throw reduction. With the TWM unit, You cannot adjust the throw ratio, its fixed. Both shifters retain the reverse lockout feature, which is why both of these shifters are more expensive than what you see on other makes out there. The Cobb DA-STS has some weight behind it. Its definitely not a light billet shifter. The billet steel upper shaft and lower billet steel pivot ball provide some nice weight to make this shifter very solid and provide you, with great shifting precision. The TWM on the other hand is much lighter, but can offset the light weight if you option up for a new weighted shift knob. Their knobs run you anywhere from $69 to $249, so keep that mind when you are trying to decide which shifter fits in your price range. So, now that we have the basic's out of the way, let's briefly talk about the install. It's doesn't matter which STS we talk about when it comes to installation. They both require some serious patience and some tools used in unorthodoxed fashions. I've got these installs down to 65 minutes. 20 minutes of that is cussing while trying to attach the spring onto the groove, while pushing the ball into the bushing, while installing the shifters pivot ball into the base. Yes, that IS a mouthful and you will get a better understanding of what I'm talking about if you have done one of these before. As i look back at this, i think doing a video of this install would of benefited people a lot better than still images. So i may go back and revisit this at a later date if one of the local guys needs some help and video the whole thing. So, finally, let's move on to the install of the Cobb Double Adjustable Short Throw Shifter. Tools & Supplies Needed: 8mm socket 11mm wrench Needle Nose Pliers 3 paper clips Moly grease or White Lith 2 flat head screwdriver, one large, one small T-20 Torx Bit 3mm Allen ( used to adjust height of knob ) [multipage=Installation] Installation: http://www.mazdaspeedforum.org/forum/pics...cobb sts/1.jpg Start by removing the shift knob from shifter. Counter clockwise to remove. http://www.mazdaspeedforum.org/forum/pics...cobb sts/2.jpg Next, give the ashtray a nice tug to remove. http://www.mazdaspeedforum.org/forum/pics...cobb sts/3.jpg Now is a good time to give the front of the shifter boot plate a tug to remove. http://www.mazdaspeedforum.org/forum/pics...cobb sts/4.jpg http://www.mazdaspeedforum.org/forum/pics...cobb sts/5.jpg While lifting the rear section of the boot plate, disengage the cup holder section. http://www.mazdaspeedforum.org/forum/pics...cobb sts/6.jpg No disconnect the small white pigtail if your car is equipped with nav. http://www.mazdaspeedforum.org/forum/pics...cobb sts/7.jpg Remove these two 8mm/Philip head screws next. http://www.mazdaspeedforum.org/forum/pics...cobb sts/8.jpg http://www.mazdaspeedforum.org/forum/pics...cobb sts/9.jpg http://www.mazdaspeedforum.org/forum/pics...obb sts/10.jpg http://www.mazdaspeedforum.org/forum/pics...obb sts/11.jpg Locate the above pigtail. You want to disconnect it, but you may have to trim off the foam and electrical tape that mazda so kindly wrapped for us. http://www.mazdaspeedforum.org/forum/pics...obb sts/12.jpg http://www.mazdaspeedforum.org/forum/pics...obb sts/13.jpg With the 8mm socket, remove these 2 bolts securing the center console to the front dash piece. Also, open up the rear console and remove the two 8mm bolts securing it to the floor. Once removed, Pull the console out and stick in the back seat to give you some room to work with. http://www.mazdaspeedforum.org/forum/pics...obb sts/14.jpg Here is what you should be seeing now. The stock shifter assembly. Pay attention to the orientation of the cables and hardware. Shifter Removal: http://www.mazdaspeedforum.org/forum/pics...obb sts/15.jpg http://www.mazdaspeedforum.org/forum/pics...obb sts/16.jpg http://www.mazdaspeedforum.org/forum/pics...obb sts/17.jpg Insert your large flat head screw driver like the above picture. Use the factory plate on the left to support the driver and provide leverage. Push the screw driver towards the passenger side to pop off the cable from the shifter socket. You will repeat this for the other cable as well. http://www.mazdaspeedforum.org/forum/pics...obb sts/18.jpg Using the T-20 Torx bit, remove the torx head screw securing the ring in place. http://www.mazdaspeedforum.org/forum/pics...obb sts/19.jpg remove the ring and place it to the side. Ok, we are now going to need a 3 paperclips and a small flat blade screwdriver for the next steps. There are two ways you want to depress the 3 retaining clips that hold the shifter base. You can insert the flat head into the slot and push the tabs in, or work the tabs from the side. The idea is to get the retaining clips pushed inward towards the shifter, while hold the clips forward using the paperclips. Once you push the tab in, slide the paperclip behind it to keep it from locking back in. Do all 3 tabs as shown below: http://www.mazdaspeedforum.org/forum/pics...obb sts/20.jpg http://www.mazdaspeedforum.org/forum/pics...obb sts/21.jpg Once you have this complete, move on to the next step. http://www.mazdaspeedforum.org/forum/pics...obb sts/22.jpg Here is the spring that is talked about in the instructions. What you want to do is get someone in the car with you. Have them pull upwards on the shifter once you get a firm grip on the upper part of the spring using needle nose pliers. Grab the tip of the spring and pull up. Once you have the spring pulled upwards, out of the groove channel of the shifter, tell your partner to yank the shifter up to remove it. http://www.mazdaspeedforum.org/forum/pics...obb sts/23.jpg http://www.mazdaspeedforum.org/forum/pics...obb sts/24.jpg It's time to bust out some moly grease of white lithium grease. You want to liberally coat the base pivot ball and the small pivot balls. Don't be greedy, use a lot. Once completed, take the rubber o-ring off the stock shifter and xfer it to your Cobb STS. Also, the gray plastic pivot cup needs to be removed and attached to the Cobb STS large pivot ball as well. http://www.mazdaspeedforum.org/forum/pics...obb sts/25.jpg Now here is the painful part... putting the STS in while attaching the spring. The best tip i can give you here is working with someone else. The first thing you should do is remove the small white/blue bushing from the side arm and attach it to the small pivot ball. This will save you some frustrations while installing the unit back in the car. Using your assistant, insert the STS, lining up the small pivot ball with the side arm, while you are pulling up on the spring. When you have it lined up, secure the shifter into the base. You should here the tabs click as the base engages. At this time take a small rubber mallet and whack the white bushing inwards to the direction of the passenger side to get it to seat. Double check the spring to make sure both the bottom and top are lined up inside the channel groove. Believe it, this sounds much easier in writing than actually doing it. The bottom picture will show you the white bushing that gets whacked by the mallet. http://www.mazdaspeedforum.org/forum/pics...obb sts/26.jpg http://www.mazdaspeedforum.org/forum/pics...obb sts/27.jpg http://www.mazdaspeedforum.org/forum/pics...obb sts/28.jpg http://www.mazdaspeedforum.org/forum/pics...obb sts/29.jpg http://www.mazdaspeedforum.org/forum/pics...obb sts/30.jpg http://www.mazdaspeedforum.org/forum/pics...obb sts/31.jpg Now its time to select your short throw shift ratio. Choose which hole you want to install the pivot ball in. The top is 30% reduction while the last hole towards the bottom is 10%. I used a little locktite blue on the threads. http://www.mazdaspeedforum.org/forum/pics...obb sts/32.jpg Tighten the pivot ball using an 11mm wrench. [multipage=Buttoning It All Up] Now its time to get everything re-installed and take her out for the test drive. http://www.mazdaspeedforum.org/forum/pics...obb sts/33.jpg http://www.mazdaspeedforum.org/forum/pics...obb sts/34.jpg http://www.mazdaspeedforum.org/forum/pics...obb sts/35.jpg http://www.mazdaspeedforum.org/forum/pics...obb sts/36.jpg If all went well, your install should look like the above pictures. Now, lets get the console and its associated parts reinstalled. http://www.mazdaspeedforum.org/forum/pics...obb sts/37.jpg http://www.mazdaspeedforum.org/forum/pics...obb sts/38.jpg http://www.mazdaspeedforum.org/forum/pics...obb sts/39.jpg http://www.mazdaspeedforum.org/forum/pics...obb sts/40.jpg http://www.mazdaspeedforum.org/forum/pics...obb sts/41.jpg http://www.mazdaspeedforum.org/forum/pics...obb sts/42.jpg http://www.mazdaspeedforum.org/forum/pics...obb sts/43.jpg Conclusion, Impressions & Recommendations: Well, aside from the nasty spring, the install isn't all to difficult. The end result makes it worth it. Prior to the install, i had the TWM Bushings installed in my car. With the addition of the Cobb DA-STS, they made no difference to how the shifter felt. So, i removed the bushings and gave them to my friend who has a TWM STS... He needs them more than i do :) The best impression i can give while driving the car now, is it feels like we have a very expensive, well built transmission. If any of you have ever driven a mustang that had a pro 5.0 power tower or Steeda Tri-Ax shifter installed, that's the best comparison i can make to it. The shifting is with precision now. All of the slop is eliminated, gear shifts are quick and positive. The additional weight of the Cobb DA-STS adds to how well the car shifts now. Rowing through the gears has never been more fun. This shifter compliments the additional power we have added to our car. Those of you who drag and road race, will enjoy this shifter as well. I ended up raising my shifter about 1 inch as i felt it to be more comfortable to me. You could further enhance the Cobb DA-STS by adding a new weighted shift knob if you prefer. How does it compare to the TWM STS? Its a night and day difference. The weight that Cobb added to this shifter has paid off and can be even further enhanced by adding a weighted shift knob. So, do we have any recommendations? Of course! After i installed the shifter, i contacted Cobb and told them i wasn't happy with how far i had to set the 3mm allen heads to hold the handle. I was afraid that someone may over tighten these screws to much and break the heads off the screws. They already beat me to the punch and made a modification to the diameter of the knob shaft to address this prior to shipping these out to the dealers. Other than that, i can't find a single flaw in this shifter. Install manual. It was well written but the black and white pictures lack some needed detail. With the assistance of this review, you will be good to go on the install. Anyways, another great product release from Cobb and thanks for sending this unit out to us. These should be available to the masses in about 2 weeks for $275 Discussion of the review can be found here. |
