This is one of the best recent tweaks on my car . For those who have a stock clutch or a weak leg this adjustment may not be for you . I do have a bad knee but it can handle it . This adjustment IS for the person with a stage two or three clutch who wants to enagage easier into first gear .
The tradeoff is having to press harder and the gain is feeling the point of engagement which enhances any launch .

This is by no means an easy job . It requires hours of taking things apart and plutting it back together just to get at it . If you are a technician reading I was told it much more involved job than the 996 Turbo in terms of time .

It's a great tansition . I highly recommend it .

 

Why would you swap a stock Turbo clutch capable of handling 680Nm torque for a GT2 clutch capable of handling 680Nm torque? Do you get launch control with that?

Anyone with a Stage II tuned Turbo should look at a Sachs II clutch which handles about 750Nm. More power than this and you are looking at Sachs III clutch solutions with sintered discs (which are apparently not a great solution outside track use).

 

Alex -
The 700 kit requires a stage three clutch . The point of engagement was always an issue even when the car was stock. I despised the power assist feature . The Gt2 conversion is not an actual Gt2 clutch but rather a conversion eliminating the power assist . It is geared towards increasing the ability to feel the point of engagement .
It is a fantastic upgrade.

 

The power assist on the tt is bothersome. Even with the Sachs stage 2 and LWFW, the point of engagement is still very numb. I think the GT2 conversion is a great solution.

 

Agreed . It's not even that hard to press for me . The engagement point is critical and the first time I drove a Turbo (stock) it was the first thing that i did not like . This upgrade offers a great solution BUT it is work for the tuner. The 996tt from what i understand takes about half the time comparably .

 

I don't have the power you guys have, so the clutch hasn't been a problem for me. I did notice from the outset that my seat adjustment was very critical in achieving a smooth clutch engagement. It's always annoying when someone else gets in the car and readjusts the seat. I have to remember to use the seat memory setting to get it right, otherwise I end up killing the engine or rolling backwards on an up slope. I believe the stock clutch should be adequate for a lightly modified engine.

 

It is adequate for a lighly modded car. Like youself I also have seat neurosis issues when its moved in ANY car .

However my complaint about the stock clutch was not a result of drover position . It was how the power assist disengages the driver feedback on making the connection .

Going to a stage three clutch makes the point of engagement even more tricky because the performance clutch grabs differently.

The conversion makes the pedal harder to press but one feels the engagement and pinpoints the sweet spot with ease .

 

Yup I know what you mean... We've been doing them for some time on the 996TT because the numbness only gets worse and more tricky on a performance clutch with the assist still in place

I have this, a UMW clutch and LWFW (Porsche RS part) on my 996TT. The evoms gt2 assist mod has made the car much nicer to drive. You need more force on the pedal...but feedback is 100x better.

The GT2 presssure plate does not have the loaded springs.

 

No problem on the 997?

How long are stock clutches lasting with mods?

 

I have seen the EvoMS kit offered by several different vendors, but I remember seeing another package (w/black bracket?) on the market. Anyone know what I'm talking about??

 

This is a great explanation of the reason a GT2 clutch conversion is very desirable. The feedback is superb and it makes launching the car much easier and extremely predictable when compared to the OEM assisted clutch.

 

Nevermind, I was looking at two different versions of the EVO kit... sorry.

 

Anyone have a write-up on installing a GT2 slave cylinder? Or a Braided line that eliminates the Restrictor that makes engagement more predictable?
