Mods to reduce drivetrain power loss?

[serialk11r]

I would reckon flywheel and wheels to be the biggest improvement that you can feel. Wheels spin slowly compared to the rest of the drivetrain but you have 4 of them and most of the mass is on the rim. 16" wheels bring it 1 inch closer to the center and make the wheel stronger, reducing the amount of metal needed. Flywheel has both large diameter and it spins way faster than the wheels.

Don't bother with bearings and gears, those cost way more money and time. If you want to repack the wheel bearing grease yourself go ahead but you won't feel the difference.

Its all a matter of perspective. For you its $515usd but for me its $712aud a wheel, then add shipping... arrrg.

Gorgeous wheels though. The more I stare at them the more I want them!

Failing that I'd have to go with RPF1's, but that seems like such and overplayed thing these days. Also not fan of the unfinished centre cap and design in general.

Because of the price?
PS some short shifters do not clear the aluminum shaft because the diameter is larger than stock

I think what he meant was it's not cost effective to spend 2x the price on the CF shaft to only save 1 additional lb of weight. For that extra price you could save considerably more in other locations. ie $500 just about nets you a flywheel and front bumper beam replacement @ 15.4lbs total savings, 10 of that rotating mass.

Personally I went with aluminum though as 2 separate carbon ones disintegrated on my Vette (and I don't drag race). The weak link is the epoxy that holds the carbon to the aluminum yoke. Over time and heat it breaks down and lets go then the yoke spins free in the carbon tube.

What I liked about the RPF1's (aside from the design) is that in 17x8 with a 245 Direzza Z2 Star Spec you're only adding 4oz per wheel. Yes it's rotating mass, but the grip you get in exchange makes the weight negligible at best.
