Lots of factors to take into consideration! Don’t buy tires, if you haven’t decided on wheels, don’t buy wheels if you haven’t decided on Brakes & Suspension upgrades, and don’t buy any suspension kit if you haven’t decided on changing spindles or tubbing your car. (DAMN!)
First, let’s focus on WHEELS. If you plan to get 18″+ wheels, you will, most probably, need a Disc Brake conversion or upgrade (11″-12″ rotors). (with 18″+ wheels, you have more tire size options, I’m on 17″)
Next, choosing your wheel size, which depends on tires, backspace, offset, future suspension upgrades, and if your car is tubbed or not. Doing this right will allow best fitment & no rubbing.
Recommendation on Wheel Size for the following example: 18″ wheels with a 1.5-2″ drop:
- Fronts: 18×8″ , 4.5″ backspace, 0mm offset
- Rears: 18×9″, 5.25″ backspace, 6mm offset
- Tires: 235/40 & 275/35
My 17″ wheel setup on Ridetech StreetGrip suspension kit:
- Wheels: American Racing AR105 Torq Thrust M
- Fronts: 17×8″ , 4.5″ backspace, 0mm offset
- Rears: 17×8″, 4.5″ backspace, 0mm offset
- Tires: 235/45 & 245/45

Again, wheel & tire setups are not enough on these classics. A lot of other suspension & brake parts play a big factor in ride height. This was extremely a frustrating part of my build. I have a detailed write-up on this –> HERE
