Default What offset for 20" running 315 and lowered 2 "

Well I figured I didn't need to reinvent the wheel

Hopefully someone is running this setup
I would like to run 315 with the tires in the wheel well
and I will be lowering 2 inches

I would also consider 19" wheels

Am I dreaming or is there an offset for a 10" or 11" wheel that will get me there?
Thanks In advance


Also is there a sticky on factory geometry for wheels and tires?
Seems that there should be

20x11 38mm offset would be really close to the fender and may need soem additional negative camber for 315's to clear ...

Adding neg. camber....?

Are you talking about running an 11" wheel up front? I know Griggs does this on their race cars, but the remove the liner which gives them lots more room, but also run an 18" wheel.

Jazzer is hoping for some clearification, from his pepe Luke

315 up front HMMMMM that would be different lol
I think he misunderstood my request

Really what I want to do is run the widest tire and wheel combo on the rear of the car that will leave the rear tires inside the wheel well

It may be that its only a 295 or maybe a 305
But I need to figure the correct offset for the rear to remain inside if possible

Jazzer do you know the factory wheel offsets?
I have factory 18" wheels on a 2008
Thanks
Greg

11" with a 315 in front would not work I was assuming a 315 for the rear is what the OP was looking for ...

295's fit with ease out back

I figured so, but you had mentioned adding some neg. camber for clearance and the '11 Stang is an SRA, so Teh Kitteh was confused

OK so back on point
Is the 305 or 295 the best option for the rear

And most wheels are llike 45mm ET
I want the tires flush at worst but prefer them tucked in a little


The new FR500 at cruzin in 20,s are appealing

Many have run 315 being flush with an offset like +53.

Factory offset on 9.5 is +45.

I plan to run 295 Michelin Super Sports with my next set up on a 10 or 10.5 wheel with an offset in the +45 - +50 range.

Thanks IA

That looks to be what I need to do without spending 4k on wheels to get the higher offset.
Most seem to be the +45 offset for the rear.
So maybe the new 20" FR500 in flat black
