Time for some new wheels and thinking about going 20x11 rear rotary flow forged wheels for the extra concavity along with 9.5" or maybe even 10" wide front wheels. My car is currently sitting on RSR SuperDown springs which is about 2" drop all around. Will also need to adjust accordingly with proper tire size + offset to clear.

Has anyone pulled off running these size spec wheels: 20x9.5 or 20x10 (F) + 20x11 (R) on their 4GS?

If so, what offset + tire size for both front & rear wheels is ideal with these specs as flush or slight poke as possible w/o rubbing?

I've pulled off the front 20x9.5 but rear no, closest I got was 10.5 and that rubbed a little. If you go 11 you might be able to but your are definitely gonna have to stretch those tires.

OP.. I don't see offset (ET) numbers from you to get exact answer...

I think even with stretched tires it will rub regardless with 20x11... I had to roll rear fenders(quarters) to make no rubbing on 20x10.5 with little stretched tires...

What was your offset and tire dimension when you rubbed a bit with the 10.5 rear? I think it may be ideal to run 10.5 in the back.

Reason I wanted to push for 11 rear is incase I end up picking up an RCF or a GSF after this car, it would be an easy swap.

I didn't specify the wheel offset for the 20s since I don't have the wheels yet, and can always specify the wheel manufacturer to dial in to a certain offset spec that would work to clear 11s.

Not looking forward to go through the trouble of stretching the rear fenders. What tire size and offset did you have with the 10.5 rears?

Might just be safe to go 255/30/20 or 245/30/20(f) & 275/30/20(r) rubber with 20x9(f) & 20x10.5(r) wheels that has preferably about +35(f) & +45(r) offset

Front was +35 and the rear was +38 and I had stretched tires.

I used these numbers recommended by Vossen when purchasing and guys here on the forum, I was still rubbing in rear on bumps or people on the back. Ended up rolling fender to fix it. Also, mine is dropped on Tanabe

- Wheels: Vossen VFS2
20x9 ET38 front
20x10.5 ET45 rear

- Tires: Continental Extreme Contact DWS 06
245/35/20
275/30/20

I see you were running bit aggressive +38 offset in the 10.5 rear; +45 offset or higher would have helped.

That's right about the ideal spec. Only I may have to spec the front wheel offset with +35 offset instead and 255/30 tires or just go with 245/35 tires like you did.

Worse case scenario I may just have to get the rear fenders rolled also if I rub in the rear with 10.5 +45 offset(4mm closer to rear strut *according to wheeltheyfit.com vs OEM*)
Unless a more sunked in +48 offset(7mm closer to rear strut) in the rear will do the trick to not rub on bumps/passengers w/o having to roll the fenders.

Let me know if you want my Set of AG SR8 spec 3. 20x10 +22 20x11 +22

ELITEGSF,

Nice wheels. How much did you want for them?

I agree. What wheels & suspension? fitment definitely looks on point!

I’m on 275/30/19 19x10.5 +22 and needed roll+shave fenders in the back. Tires stretched a bit

+22 offset on 10.5 wide rears is absolutely aggressive poke. Being a wheel size shorter than a typical 275/30/20 aftermarket set up, I’m sure it doesn’t help with clearance.

On my lowered HS250h that’s fwd I run 245/35/19 19x9.5 +22 squared and the wheels definitely poke out and barely clears.

Post pics of the aggressive 19” wheel setup on the car if you can!
