Hey all! I'm wondering with 17x7" in front and 18x8" on the back, what back spacing do I need? I'm planning on doing a 4 wheel disc conversion in the spring. Thanks!
Some aftermarket disc brake kits (like the SSBC kit I used) will push the front wheels out 3/8" per side compared to factory drums. You will have to know that before ordering your wheels. With a 16" x 7" rim up front I needed 4" back spacing with a 225 tire. For the rear I have 16" x 8" rims and needed 5" of backspacing with a 255 tire but I had the rear narrowed a 1/2", so 5.25" would be a better choice for a stock rear.
