What size tires and offset would work best for
a 99gs 400

I will have 20 x 8.5 front
and 20 x 10 back

The know that offset will be important as I am moving f
from a '19 wheel to a '20 wheel.
The car will be lowered using Tein coilovers.
Thanks for your help

 

if you wanna play safe, go with 38 fronta nd 44 rear.

tires, 245/35 and 275/30

 

could you stil have car lowered at least 2 inches with that type of offset and tire?

 

if you are on 19, yes, no problem. if you are on 20s, if you lower it to 1/2 finger gap or no finger gap, you will rub the top of the front fender

 

So what would be the proper offset for 20x8.5F and 20x10R? I have adjustable suspension I would like to at least have 11/2 drop with that wheels setup. thanks

 

well it's not about offset anymore, it's about the out of spec wheels setup. check with synergy and jawnthen if you want, they have that issue, and as long as you have 20s with low enough drop, you will get that
