826M Square Set Up

BLKSAPPE92 · 04-09-2022, 02:10 PM

So I had some time yesterday and decided to put my right rear 20" on the left front and my 19" on the right rear and drove around the shop parking lot with no rubbing or issues wheel sits about were people are going with the spacers you might do the smallest spacer on the rear and non on the front.

So.... school me if I do the math wrong....

Square 20" x 10.5" et20 would mean:

Front 12.7 mm increase (equal to 12mm spacers)
Rear zero increase (equal to no spacers)

On the offset thread (above), I think 12/10 or 12/5 (F/R) spacers look best for offset...

So stock wheels or wheels with stock (et20) offset would give you:
Front: +12.7 push out of the fenderwell (prob. no scrub)
Rear: zero push, or use 5/10/12 mm spacers to flush tires as desired

Frankly, it's easy to find 20x10.5 et20 rims and front +12/ rear +10 with rear 10mm spacers is a great look IMHO

Thoughts? I'm looking for an easy to manage set of all-season street wheels/tires with the ability to rotate tires or replace two tires if needed....instead of all four. I'll keep the 'pretty' wheels and summer tires for nice days and nice roads.

I've been running 20" 30 series for 4 years with minimal issues (once I got off the runflats). 285/30/20 is same price as 19" for all-season...why not?

It looks good! Only driven the car around the workshop so can't give any feedback on whether this would work in the long run but there seemed to be enough clearance.

This first picture is lowered in the edit to see what that would also look like.

Hi Imran

Did the 10.5 et20 fit on the front wo any spacers etc - how much inner clearance was there ?

Thanks BP
