Hey Ric,
Yeh thats the model! My old rooted clutch you see above was a cushioned button. It served its purpose well, I think 5 years of driving it took before it wore down like that. The killer for it was limiter launching at the drags on semi slicks.
As for the new button, you will get used to it! My mate has a twin plate nismo clutch and he can use it like a normal clutch, you wouldnt even know. Give it a few weeks, you will adapt to the severity of it.
Definitely dont slip or ride it. Basically learn the revs that it seems to engage with best, and you should be fine. You just cant get lazy with them... because they will snap your neck off if you stuff it up lol!
How much power does your car have? If it is a near standard 33 gtst, the cushioned button would have probably been a better option
