Aluminum flywheel

Now it's a a real race car!
Indeed it does change the whole car, for the better

The revs just seem to be more connected to your right foot. The only downside I've found on the track is that when downshifting, the revs fall to idle so quickly with the clutch in...requiring a quick efficient heel-toe technique. I've almost had the rear end come around a few times when I let the clutch out with too little revs.
You will never want to drive a car with a heavy flywheel again.
Not that you have a problem with rolling burnouts, but you can probably add 10mph to your burnout speed now

. Looking forward to seeing you at BW.
