XTD Stage 4 clutch (opinions needed)

[Onefast99gsx]

Hello xvegan- I appreciate the 1st hand experience info on this. Yes, the slop in the motor to tranny would probably cause unecessary wear on the plate fingers. Looks like the Stage 3 setup is good for around 350hp. When I ran my best time of 11.97 I was probably around 400hp. Is there any reason why I wouldn't want a stage 4 disc? I guess what exactly does a sprung vs. unsprug disc do? I'd prefer the stage 4 for the same price unless the lack of springs is gonna make it be a bitch to drive especially in the city.

Thanks.
