I'm looking to go as wide as possible on my build. The car is down for a fresh bottom end (made ~550 on the old setup) and I'd like to find a little more traction if possible. Current setup is a 245/275 and wheel specs are:

Front: 19x9 +41
Rear: 19x10 +45

I'd like to go 275 and 305, I'm on Tien Flex Coilovers so height isn't an issue and my fenders are shaved flat (I'm not afraid to modify. Just curious as to what roadblocks I might run into.

 

Bump. No one?

 

I run 255/275 Kumho XS on Enkei RPF-1. Fit fine with stock suspension and alignment, no rubbing anywhere at all. These are 17" though!

 

For the rear:
295/30 should fit on a stock shaved fender. 305 might required a slight pull. You might have to put a small spacer to get the tire off of the suspension because it's going to bulge on a 10.

For the front:
I don't have much input. I think it may be a little too wide. Concerned about hitting the suspension like the rear due to bulge. Nothing a shave/possibly small pull and spacer can't fix.

 

I think it was tturbopimp that was running a 20x11 +47 on a 305/30/20 tire with just a shave in the rear. He might be able to give you some insight. Good luck man!

 

research..... this had been discussed before

 

I have a 04 GS300 I would like to get some rims. What best size to get? I was think on some 20×8.5 &20×10. What u think

 

thats exactly what I was running....just sold them though. Im now looking to drop down to a 19" so I can get a stickier tire to fit out back....maybe the R888 or similar.

 

boom thread back to life. Only guy Ive seen with 11" wide wheels. Hope you still remember how they were!

Considering 11" wide wheel and looking for the right offset on stock suspension. Will probably do 18s or even 17s on a 315 tire.

How was clearance on the +47 offset? Were you able to fit larger calipers?
Stock camber/toe?
Do the tires stick out the fender 0.5" / 15mm?

I may end up going with 10.5" or even 10" because its just so hard to find 11" on a 17 or 18 wheel with these 45-50mm offsets.
Dont wanna splurge either. No HRE's for me lol

 

How you gonna say 550hp and not show us a pic of that beast
