| Great postings; very entertaining--and educational. What I take from all of this is:
1) You'd have to have a *lot* lighter tires and/or rims to notice much difference in the real world (FWIW, most of the car magazines would not consider 0.2 0-60 difference to be "significant."
2) You'll probably improve your times a lot more by practicing your launching technique and finding sticky tires--regardless of their weight, than by going for the lightest tire/rim combination.
My bottom line? I guess I have a couple of them:
- I can't imagine anything much harder on a car--or worse for the lifespan of the drivetrain--than running a lot of all-out 0-60 tests.
- I'm a lot more interested in having strong wheels than light ones (hopefully both can be good-looking), especially if I'm driving on real-world city streets.
YMMV, of course--I'm really not trying to pick a fight. Thanks again for the work, Fly Boy!
