SOUTH SIDE PERFORMANCE INTRODUCES WORLD'S FIRST SST UPGRADED CLUTCH PACKS FOR THE EVO X MR AND RALLIART

Sioux Falls, South Dakota (April 17, 2009) – South Side Performance has become a name in the R35 GTR market as the company that makes and supports some of the highest horsepower GTR‘s. With a handful of fist's for the extremely of what some say is one of the world's most advanced sports car under its belt, it has spent more than a fair amount of r and d time with the GR6 twin clutch transmission and this time has allowed the company to find some new ways to beef up some of the weak points that seem to be issues that are not unique to the GTR's dual clutch box, but are shared by nearly every dual clutch transmission on the market today. After many phone calls and hundreds of e-mails, SSP decided to go ahead and start work on their own TC-SST upgrade solution, using what they had learned the GTR.

So after a flood of emails and days of filled voice mail boxes, we would like to officially announce Project Goliath TC-SST. During this project we are co-operating with a few individual SST owners as well as one major staple in the Evo X tuner community to produce a solution that will end the bickering between GSR owners and MR owners over whose car is better. The goal is to use hundreds of hours of development and R and D for the GTR's GR6 to create a wide array of components for the SST transmission in order to increase its ability to support high horsepower applications. SSP has experience with high horsepower AWD cars and knows that clutch packs are going to be a point of weakness once certain power levels are exceeded. So, we are responding to the known limitations of high torque applications for MR owners and have designed a solution to increase the torque holding capacity of the SST as far as we can beginning with a clutch pack set that should well exceed 400 ft lbs of TQ capacity, with an even more capable set of discs to follow soon after.

Specifications:
At SSP we believe that one size rarely fits all and it is because of this that we are offering two different models of clutch packs. The first of these packs is out RT clutch set pack, which is designed to increase the TQ holding capacity of the transmission by a significant margin. This increase in capacity is a result of the new discs' 25% greater gripping force than the stock clutch packs due to an increased surface area. The disc itself is a complex compound of cotton, carbon fiber, synthetic organic fibers, and other materials. These new materials add to the strength of the discs while still retaining the properties that allow it to hold up in the submerged oil environment of the SST's valve body. This technology is tried and tested as it is a compound we spend months of R and D working on for the GR6 Dual Clutch box for the R35 GTR.

The RT discs are meant for customers who want more power than their existing discs will handle, and will handle high horsepower application with a TQ rating of 438 Ft/Lbs of TQ @200 Degrees F. This is a significant factor because the torque capacity of the SST clutch packs are a combination of strength and durability of materials used for the discs themselves and temperature of the transmission oil that the Discs are submerged in.

Not being the type of company to solve only half of the equation and leave the rest to chance, we will also be offering a SST transmission cooler that is essentially a three part solution to keeping temperatures in check. This solution begins with a specially designed deep dish oil pan that allows for 4 Liters of increased trans oil capacity, and continues with the addition of a high volume oil pump that pushes the oil thru a closed loop system which contains a dual fanned bar and plate style cooler placed at the rear of the car in order to get it as far away from the heat source as possible. This is the same basic design methodology that was used on our R35 cooler, but has been customized to improve the weaknesses in the SST cooling abilities from the factory. The cooler will be available as a standalone option for $2,200.00 or as a package with the clutch discs for $3,150.00. This is the first solution for owners who are worried about breaking their clutches and want a comprehensive solution other than buying an entirely new transmission.

This upgrade is extremely delicate in nature, and as such it needs to be performed by the right shop with the right equipment and experience to get the job done correctly. Because of this, it cannot be done at just any transmission shop. As a result, you must bring your SST equipped car to a shop with experience working with the SST, or ship the car or transmission directly to SSP or any of their soon to be released partner shops with facilities to do the upgrade. This modification is only one part of a package solution to allow any SST owner to strengthen their transmission as a whole and allow SST owners to hold the power that their GSR counterparts can and more.


Price and Availability:

This upgrade is available for pre-order for $1,199.00 for the RT Clutch Packs with the first shipments in roughly 30-45 days. Payment of half of the retail price secures you one of the first clutch packs that goes into production so sign up for your pre-order today by submitting your request to: These are going to be sold through MAPerformance; a vendor on this forum. chris@maperformance.com


"Pictures will be in main thread"

Part of me was hoping for much more tq capacity but i guess since the PR didn't list the OEM tq capacity I'm not sure how much better these really are.

When I'm at the point to start upgrading the power of my car, I'll be on these options immediately.

 

I would think/hope that this is merely the first step, and that more clutch pack options will arise in the future.

 

They were holding TQ rating of 438 Ft/Lbs of TQ @200 Degrees F in testing and over 500hp! Unless your goal is far beyond that, then these are a huge upgrade. And yes, if you read the press release, they will be releasing another version eventually for people who want even more than that.

 

This is absolutely great news for all of us with SST transmissions!! Screw those Mitsubishi stealerships for fixing our cars. I never even trust them anyways. I will be doing this step along the way while upgrading performance mods. I have been debating to get the 2010 EVO X MR since I already have the 2009 RA. I want to keep the RA for DD and then this monster MR for fun use along with my other project that I may be in the process of doing. My other love are the Cobra Mustangs. These two cars are the greatest things that I have driven in my lifetime seperately from the exotic cars which I have also driven some.

 

2010 mr ftw!!!!

 

This is good news! Any reports on pricing?

Excellant can't wait to order mine!!

 

Does anyone know if the upgraded clutch packs will allow for the same (relatively) smooth and seemless shifting as the stock set up? Will the stock tranny ECU know to slip the clutch appropriately being that they're much more grabby now? Any chance of the car stalling (like a regular manual) if not enough gas is provided by the ECU since it's not slipping as much?

Any estimates on intall time?

Thanks!

 

I think that's a very important question. I don't think anyone has determined just yet how the TCU manages the clutch feathering, so I guess we'll just have to wait and see once voodooman is up and running

I'm also curious as to the engagement method used. Is there a spring loaded-type pressure plate thingamabob like a standard manual, or does it use hydraulic pressure to mash the clutch packs together? Either way, some of the limitation must be placed on the maximum amount clamping force the system provides.

I guess it'll all be made clear in due time.

 

This is good news! About time some more made some sst parts!
I would also like to know how the TCU is going intergrate with the new clutches. What about the "slow down" function?
Will there be TCU tuneing avaliable?
Does any one know when the "slow down" function engages?
Can we get more pics of the trans cooler? Can we get pics on how its mounted? Pics of the lower pan?
What other upgraded do you guys have planned?
Are you guys going to offer a DIY guide to install these clutches? I know some of us live in small town/citys so its not practical to take our car to a shop out of town. I also don't trust other people touching and modify my car. I am a DIYer and i do things my self so its done the way i like it.
Have you guys done any hard stress testing to find the failure rate?
What does the price include? Does it include oil?
I know the kit just came out and you dont want to reveal too much about the kit but i am just curious and want to know what i am getting before purchasing.

 

Well, it doesn't appear that the car is up and running just yet. So, besides their experience with similar products they offer on the GTR, it doesn't sound like the gearbox has been tested, as it is a customer's.

As for the "slow down" issue, AFAIK it's directly related to the trans oil temp - which should be resolved by that MASSIVE trans cooler.

 

+1 I think its a great transmission.
