They're not, its the type 371 .. however seeing those weight numbers was shocking. I thought they were heavy so I said 25# range but .. jeeze !
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.
