I have a 1992 rs with stock ride height. I want to run 19x9.5 on all four corners with 275/35/19 size tires front and rear. Do i need to make any modifications to make this fit?
the wheels im looking at have an offset option of 20mm or 35mm which i know nothing about. will someone please help me.

 

A 35 aspect ratio is going to put your tire diameter at 26.57". That is a bit tall in the front and you likely will have rubbing issues. I try to keep my diameters to 26 and under although some say they prefer the taller tire. I'd do some more reading. Stock 3rd gens are a 0 offset wheel, which means the inside mounting surface of the wheel is dead smack in the middle of the wheel. Running a wheel with a 20mm (.8") or 35mm (1.4") offset would mean you would need to run a .8" or 1.4" adapter. Meaning, the wheel with the 20mm offset has its mounting location (in relation to the wheel) .8" away from a stock wheel. If you didn't use an adapter, the wheel would sit inside the wheel well .8" more than stock likely causing all kinds of rubbing and fitment issues.

 

On stock rims should be indicated wheel outreach( ET)What's the difference between stock and your new rims?
