They will fit fine i just installed the GS-D3 285 40 17 on my stock chrome rims with 255 45 17 on the front.I have had the pull to the right for along time on my original tires and since i put these new tires on my car drives perfectly straight now and alot quieter going down the road to.
I'm in the process of going GS-d3's in 315/35/17 rear and 275/40/17 Front. I've got a set of 3/8 Undy spacers from svtperformance.com and went with Steeda/ARP studs. Also machined IRS bolts. Just want good piece of mind.
