Not much different than SuperCoupe Performance, they are 170.99/wheel for the black speedstars.
If I buy Mustang wheels, they are between $130-180/wheel depending on style. Tires are essentially the same for the ones I want, between $130-150/ even for 18". So if I pay $170/wheel for ones that already fit, I don't have to spend an extra $100 for front hubs, and an extra $300 for rear hubs, plus the shop time to have them pressed in, and the extra time for me to take the knuckles down and get them to the shop for pressing.
So, if I go with the 18" speedstars, I'm at $680+shipping for wheels, 560+shipping for tires. $40 for mount/balance, so $1280.
If I go with the 17x9 Cobra R's, it's $560 for wheels, $560 for tires, $400 for hubs, let's say $100 for shop time, so $1620 all told. Not sure I want to spend an extra $400 just for a more aggressive offset.
Or, if I go with the 5 spokes posted above, they'll sit approxmately the same in the wheel well, give me a few more tire choices, are 17x8 so the tires will wear better than the big wide tires on my 16x7 currently, come with the hub adapters, lug nuts, and they'll even mount/balance the tires for me for free.
I appreciate the thoughts, it's got me thinking. Either way, I'm spending $1000+ on it unless I find some very good used wheels somewhere with no curb rash, so I'll have to weigh it out in my mind quite a bit before I pull the trigger.
