Ice - This is the best attribute of the SS-Trim, IMO. Engagement is more crisp than stock but it is NOT the on/off switch of the more aggressive Spec clutches. This is definitely the clutch that I would install in my own car.
I couldn't disagree more. The ST-Trim is a HEAVY clutch. Also, it is prone to have a bit of shudder/chatter on first gear engagement. We have installed at least 8 of these clutches- so we know of what we speak. It is our sole recommended clutch for the TT cars. Other than a heavy spring feel and this occasional first-gear chatter, it is a nice set-up and it can certainly hold the power. All told, we have literally hundreds of 1-mile sprints on this clutch and never a sign a slip or failure.
BUT, back to the OP's question. What clutch for a car with 900 or less lb-ft of torque? Why deal with an ultra-heavy clutch feel and a chatty on/off first year engagement if you dont have to? This is why I would recommend the SS-Trim. It has a better feel than both the Stillen and OEM (IMO) and can still handle the power easily up through and including Whipples at 19 psi. Thus, my recommendation. For the record, we have done approximately 6 of these installs - so we have ample experience and owner feedback of each clutch. Oh, and it is also $1000 less than the ST-Trim.
Finally, we can supply the SPEC clutches for anyone that needs one.
