what is the differences between the Non turbo S4 and non turbo S5 driveshaft? are they swapable? Looking for an effective way to decrease drivetrain power loss. I found a carbon fiber driveshaft that has about a 5% gain in hp. Looking to combine this with a lightweight aluminum flywheel (not sure which one yet...i like the ACT streetlite tho) and a organic/street disc clutch (also not sure, probably ACT) Will i run into a problem if i use S5 tranny parts on my S4 tranny? IE. the ACT streelite flywheel and street clutch. Im not sure if they have it for the S4 model. thanks

 

I think they are the same. The difference are between the non turbo and the turbo driveshaft. S4 or S5 doen't matter. The transmission are the same.

 

yea i noticed some places dont seperate the years and some do? that really confuses me. But searching i found a kit that is decently priced, im considering buying it.
9.5Lb aluminum flywheel, counterweight, hardware and bearing kit, ACT street clutch set. -$750.

 

is there any chance that the S5 is a larger diameter?

my friend took apart this parts car that had a thicker driveshaft then our stock S4 N/A's. The weird thing is that it bolts up to the stock drivetrain
