    Hey everyone, I need help deciding what rear wheel set up to go with. My car is a M6 whippled 2013 GT making about 650whp, it will be used mainly on the street ( weekend car) w/ occasional visits to the strip. My stock Brembo wheels and tires are not cutting it lol. I’m currently looking at getting Forgestar F14s either in 17x10 or 15x10 w/ drag radials. I know I should use slicks for stick car on the track but it’s mostly gonna be on the street so I’m leaning towards DR. I would really appreciate it if I can get some input on a few questions and any recommendations would be much appreciated.

    1. What are the pros and cons of using a 15inch vs 17inch rear wheel on the street? As far as high speed wobbles, durability, cornering, ect.

    2. Would a 15x8 wheel w/ a 275 width DR hold my power level on the street? I’m just hesitant of 15x8 incase I need more tire width for traction.

    Pretty much just looking for a set up that works and is most practical for street use but able to handle 600-700hp.

    Thanks in advance!

    I have a ‘12 5.0 mt82 NA on 15x10 with 555R and no issues at all. Car still spins in 2nd gear but controllable. I would think at your power level a M/T SS or Street R for the street.
    I use Hoosier QTP slicks only for the drag strip and would highly recommend.

    Go with the 15x10, I run these with MT Drag Radial Pros 275X60 and can hook on the street (M6 trans) when temps are above 70F. Im at about 650rwhp. 15" tires are cheaper too and I think look better.
