Transmission upgrades for Evo MR and Ralliart

Sst Upgrade Press Release







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

Nice !!!

Ok, so add the clutch upgrade to the "planned" list I have so far:

ECU flash
New exhaust
Drilled Rotors

Like all of these, I am going to have to wait until I am through the first couple years of warranty, and until I have substantially used up the stock parts that I have. Besides, I've already got a 3K bill coming my way soon to put winter wheels on, and I like having some money to get the car onto the track, which is after all why I bought this car.

Thanks for the heads up.

Indeed, their first transmission cooler location was ass but they have a front mounted one now

So does AMS now

The biggest thing so far is the overheating, even with stock power. Upgrading the cooling should be the first step, then once you get over 300wheel torque then you can think about upgrading the clutches

I wouldn't drill the stock rotors. I've heard bad things about drilling actually weakening the rotor that wasn't designed to be drilled. Best advice if you want is get some rotors that were designed with holes in it, or better yet get slotted rotors instead of drilled.

I'm going to get an Access Port I think because that gives you the ability to flash absolutely back to stock whenever you go into the dealer, so you don't have to worry about warranty, and you can flash it yourself instead of having to go to your tuner to flash back to stock with ecutek

For ECU, I'm planning to go this way:

But the transmission upgrade will come first.

As for the rotors, no I wouldn't drill the stock issue. I'll replace them with superior quality when they are well and good used up. That isn't going to take long the way I'm going. That'll be the first upgrade.
