Anyone have any experience with the Spec 3 plus? Prior to the blower, the Stage 3 lasted about 20K. I road race and do high speed auto-x and may do 2 passes a year down a drag strip, but with 4,400lbs car with 516rwtq, I would prefer to go with a springless hub and was leaning toward the 4. But would a 3+ be better?

Let me add that a twin disk setup would be ideal but to make a long story short after 3 trany drops the Street Twin is heading back to CA and I'm going back to my stock flywheel.

Any feedback appreciated.

 

i'm pretty pleased with my spec 4

it is touchy to drive in heavy traffic, and it grabs like crazy when hot. but it seems to drive fine.

i installed a light weight flywheel with the clutch and that makes it noticably trickier to take off from a stop under "gentle driving" conditions. since there is not much slip with the clutch.

 

Thanks. I don't street it much. I'm thinking stage 4 at this point

 

Go stage 5. They just say "race only" to scare off people who arent worthy.

Ive got a Ram Powergrip HD and its holding my 383 just fine to this point and Im happy with it. I kinda like the grabbyness. I actually want a stiffer one next time. From what I know... the quality of Spec products goes up drastically once you get into 4 and up. The 1-3 are crapshoot hit or miss. Some love, some hate... you wont see much hate spread about the 4 and up. Think about it.
