Fitment question

[RonaldoM03]

I want to run a staggered setup for my gt with 20s all around.
For the front I want 275/35/20
For the rear I want 305/35/20
Question is, what is a flush offset & diameter for both front and rear?

A few comments:
- The answer depends on your camber.
- Truly flush fitment tends to look like it has some "poke." As such, some folks prefer the look of 3-5 mm less than flush.
- A 305/30/20 is much closer to the OEM tire diameter whereas a 305/35/20 is over an inch larger.

Front flush fitment for 275/35/20:
20x9.5 ET26 w/-1.0° camber (go w/ET29-31)
20x9.5 ET21 w/-1.5° camber (go w/ET24-26)
20x9.5 ET17 w/-2.0° camber (go w/ET20-22)

Rear flush fitment for 305/35/20:
20x11 ET48 w/-1.0° camber (go w/ET51-53)
20x11 ET44 w/-1.5° camber (go w/ET47-49)
20x11 ET39 w/-2.0° camber (go w/ET42-44)

I built a calculator to do this recently and it seems to be pretty close.

LOUSY tire selection in that size. And if you're gonna bother, just go up to 10" wide up front. You can still run 275/35 if that matters that much.

If you want rake, just buy Steeda's rear spring preload disks in 3/8" thick.
RU trying to pretend you have drag tires on?

See my post here for a good fit on stock suspension. I have since removed the front spacers and I would go with a 275/35 on my front 9" rims: https://www.mustang6g.com/forums/th...termarket-wheels-and-tires.15709/post-3249722

I’ve got 20 x 10.5 and 20x11.5 wheels
285/30 front and 315/30 rears.
+24 and +55 offset.
