Correct me if I'm wrong but ..

1. Conventional wisdom says 1# rotational / unsprung weight = 7# sprung weight.
2. Conventional wisdom also says every 6 lb lost is similar to gaining 1 HP.

TE-37 in 18x8.5 is just under 17.5# and the 18x10.5 is just under 19.5#. Assuming 30# for my current wheels .. that's rough about 10# rotational mass X 4. A total of 40lbs rotational mass total difference.

Applying conventional wisdom rule 1 would mean the new wheel will feel like driving a 280# lighter car.

Applying conventional wisdom rule 2 would mean the new wheel will feel like the car has 46.6 more HP !?!

Definitely sounds like I'm going with wheels first.


What is the offset on the Volk rear wheels ? At 10.5 you'll have a very difficult time trying to clear the perch on adjustable coilovers if you ever go that route.
