My 350 has 852rwhp and the 305s are just inadequate. As to the weight, I'm upgrading to forged Mg rims, lightweight ceramic brakes, lighter clutch flywheel, & a CF driveshaft soooo....we'll be good. As to tramlining, that will be addressed with the revised rims and tire combo coming (you may already know 350s tramline from the factory so my mods will reduce or eliminate it). To your width point, the car is only going to gain Hp going forward so at a minimum, 325s or perhaps 345s will be in order but for the latter, it will need a WB to accomodate.....I'll think on it ....I'm just not a fan of the potential months long wait time for WB completion). Cheers.
I'm pretty sure there are people running 345s under the factory rear fenders on GT500s so that means they should work on a 350, too. Signature built some 12 or 12.5" rear wheels that fit if I recall.

Cool....I'll look into Signature's offering if I decide the 345 width. Surprising it might fit w/an OEM rim so again, thanks for the heads up Champale.

I dont think so. Not without sticking all they way out or significant modification. Widest I've seen is 325 unless Shelby widebody

Uhhhh a quick search in the Signature (Terrance/50 Deep) GT500 wheel thread pulls up multiple references to him doing it. Forum member markboris and others have done it.
