Various S197 Wheels Test Fitted on S550 GT PP - 18x9 / 18x10 / 19x9

boardkat · Jan 5, 2015

Finally received my GT PP on Friday - so I spent some time test-fitting wheel/tire combos leftover from my wrecked '13 GT Brembo car on the front. I'd heard that there might be issues with barrel clearance for any cast 18" wheel, while 19" shouldn't be a problem. Here are the results:

18x9 +35 and 18x10 +43 SVE Drift
Does *not* fit. Caliper interference with the barrel, unable to mount.

19x9 +42 OEM Brembo Package
Fits. 13mm clearance.

19x9 +42 Boss 302S Replica
Fits. 16mm clearance.

19x9 +36 Forgestar CF5V
Fits. 21mm clearance.

Off subject, but what size Direzza are you running on those B302 wheels?

275/35R19 - slightly pinched, but the stiff sidewalls of the ZII handled the 19x9 just fine (and i raced on them for a season and daily drove them afterwards without issue).

Yikes that sounds squished! Do you happen to have a picture of wheels from a side view? Curious how badly they bulge. Thanks!

no pics handy, but it's really not that bad.
squished is a 295/30R19 Hoosier A6 on a 19x9 - a fellow competitor even managed to shoehorn a 315/30R19 on - gotta love stock class rules :headbonk:

I always thought the brembo wheels from the S197 would make a great winter set as the snow wouldnt have much space to get stuck in the spokes

AWWWESOME! I have a set of the Brembo rims lying around...unfortunately I already bought a set of staggered Blizzaks that I mounted on my PP rims. Perhaps the 275's would fit OK on the 9" wide rims...we'll see next winter.

The big question is...will the 2015 lug nuts fit with the Brembo rims???

Thanks for doing this OP. Great info.

anotherneon · Jan 8, 2015

thanks for the info. By chance are you selling any of the wheels?

Nice.

I foresee a set of the staggered Boss 302S wheels in my future. :cheers:
