Does anoyone know what a good offset would be for a 9 inch wide up front and a 10 inch out back? I plan on running 235/50-18 up front and 275/45-18 out back..

 

I think you'll be fine sticking with the stock offsets which are in the 45-50 range. With you being lowered, I'd be a little concerned about the rears if you go with an offset that pushes the tire out much farther but it depends on how much you're lowered. If I were you, I'd certainly consider 255's up front (which should really plant well) and 285's rear (since those 10's might look a bit overwhelming for a 275).

 

Thanks.. I'm trying to figure out the correct offsets for 8 or 9's in the front and 10's in the rear. I have looked around for info on rim comparisons on lowered ( lowered 1 in the front and 1.5 in the rear) S197 with no luck. By the way the pic in my sig is the car lowered.

Also in looking at the rears that are on it now, going to a 10 inch would be good if the backspacing was increased the amount over the stock wheels.

 

AM list the 18" DDB's I purchased as 34mm on the 9" and 45mm on the 10". I am confident I could lower my stang up to 1.5" with no rubbing problems and run 255/295 staggered. Nuke is on the money with the tire selection bro, lowered I would go with the stock cobra staggered setup of 255/285. Hope this helps.

 

The wheels I'm looking at have the backspacing below, does that seem good?

18x9 = 6.46 backspacing
18x10 = 7.15 backspacing

 

That backspacing would be about the same as what I purchased, I would think. Should work fine. What wheels are they btw?

 

These are them.

 

If these are the one's you are looking at...it's all good bro, do the deal

Site list them as 38mm on the fronts and 42mm on the rear, and they will fit just fine even with your drop. I would still recommend you go with 255/45/18 up front and 285/40/18 on the rears. Check out member D'prived, his stang has a similar drop as yours with this tire setup. Looks f'in amazing!

 

Yup, thats them!
