if i get rid of my mustang gt,i want to swap wheels to srt8 or rt.
mustang gt 5x4.5 114.3 high offset
challenger 5x4.53 115 medium offset

on my car now 20x10 [285] on rear and 20x9 [255] on front
offsets, +38mm for the front and +48mm for the rear

any tire experts out there that make sence of this for me? :dunno:
i dont have a challenger to test fit.

[wheels are also from american muscle.com bullits,deep dish on rear.]

thank you

Those will not work, too much offset. Ideal fit for a Challenger would be
20x10 [285] +25mm for the rear and
20x9 [255] +20mm for the front

Bolt pattern is fine, those offsets will rub the inner fenders, suspension components.

Look at these charts. A smaller offset number pushes the wheel out more.



Not enough POSITIVE offset gives you this.

05+ mustang wheels won't fit challengers, 04 and older will work due to offset.
