I went with the TSW wheel & tire kit from American Muscle.
B/c when looking around at the weights, the TSW's were about 5 lbs lighter PER WHEEL
than most of the AMR & stock wheel weights. It might not sound like a lot, but 5 lbs per wheel x 4 wheels = 20 lbs off of unsprung / rotational mass. It really amounts to a pretty large difference in performance.
Example - basically same shape/design wheel:
AMR 19x8.5" wheel = 26.9 lbs
TSW 19x8.5" wheel = 21.9 lbs
The only drawback is the rear TSW's are only 9.5" wide (assuming you go staggered), it will limit the size of tire you can put on.
I didn't think I would need more than 285 wide unless I SC'd the engine, but going up from stock 245 to 285 rear did not help nearly as much as I was expecting it to with spinning the tires.
Forgestar are also similarly lightweight, but do come in wider size. But I preferred the appearance of the TSW.
Ok, the other drawback is they're more expensive. BUT you get what you pay for. I've learned do things right the first time, so you don't have to redo it & end up spending more the 2nd time around. ie: I see a lot of people going cheap with upgrades, then they buy a more expensive upgrade later & sell the cheaper upgrade... losing a lot of value on the sale of the cheaper initial purchase.
P.S. FYI, to find the wheel weights on AM you will need to look at the individual tire specs (not wheel/tire kits). You can also go look up tire weights on tirerack or the manufacturer's websites.
