Help choosing new offsets

Currently have:

20x9 30mm 255/40/20
20x10 48mm 295/35/20

Want to get:
20x9 25 or 30mm, same tire
20x10.5 35, 40, or 45 same tire

Current setup.


I'm lowered more than 2" on coilovers.

The rear only runs when going in and out of driveways as I go in at am angle.

I want to get 25mm front and 35mm rear but afraid rear will rub.

Play it safe and get 45mm?

For reference the wheels in my signatures are as follows.

20x10 +48
285/30-20
Lowered on Eibach Sportlines (over 2")

I know 20x10 with 48 is good.

My new setup is 10.5 but not sure what offset to not rub.

i've got 20x10.5 with the same size tire on my '12, can't find the email with the specifics, but I'm pretty sure it was a 35 offset on the rear. No rubbing at all, ever.

Oh if you can confirm that would be awesome.

35mm offset would give the face of wheel more concaveness.

I went with a 40mm offset.

I went with 45mm offest, 20x9.5 Steeda Spyders..

Trying to find out what the offsets were from the place I ordered them from. If I get no response, i'll take one off and measure.

I think with 9.5 you can go with 45mm and even up to 35mm? I think RTR wheels are 9.5 with 35mm.

Hey OP where did you find Saleens in 20x10? I've been looking and didn't see any.

I was considering RTR, but their only available in 9.5 width on 19 inch wheels .. When it comes to 19" tires, you have a very limited selection of sizes to choose from compared to 18" and 20" tires.. Prices are also much lower for 18" and 20" tire sizes over 19's as well.. So I went with 20's instead..
