Spec vs. Ram
Trending Topics
I plan to make 600rwhp on nitrous and wanted a clutch to hold up to the abuse and not have to dick with it every 10K miles. As per TSP I run a RAM 910/VDS PP and Fidanza alum flywheel which has been the hot ticket for me. I have yet to use the nitrous; however have about 15 passes at the strip on stickies, 6 hrs worth of hard road racing, and 20K very very hard street miles.
I'm more than happy with it and would buy it again. The only downside is that it has a stiff pedal (which I'm totally used to) and in stop and go traffic your leg gets a workout is the only downside. I have 3:90's which eliminates most of the chatter from a stop. I get clutch chatter maybe once per 50 times taking away from a stop. You just have to slip the clutch a bit which eliminates all chatter. I have never smelled burning clutch ever and once you let out the clutch this sucker instantly grabs.
If you have only around 450rwhp I would install the LS7 clutch/GTO LS2 flywheel setup as it has near stock pedal feel and lots of grip. If you plan to punish the car and squirt nitrous get an appropriate clutch for the abuse.

spec 4 and the ram hd.
I chose the ram hd because I wanted a sprung disc that
would stay together, and I didn't think that the springless 4
would be quite what I wanted for a street/strip car.
My power levels should be in the ballpark of
mid 400hp NA to 600'ish HP on spray.
i have 25k and 100+ passes on my stg3 "x" pad and have seen alot of other specs last just as good the only ones ive ever seen an issue with is the 3I which isnt available anymore. also after driving cars with a stg 5 that will be my next clutch.
