Hello all,

I have an 03 vert that is SRA swapped with a 94-98 SRA. It is currently running rather large wheel spacers with 17x10.5 black chrome cobra wheels. The wheels are rough so I ordered machined deep disk 17x10.5 wheels to run on the back thinking I could eliminate some of the spacer. Is there an easy way to figure out what size spacer is needed? I live in a small town and am hoping to get these mounted this weekend so I need to order spacers today to have a chance at that.

UPDATE:
Well I feel like an idiot. I went out to measure the current spacer and its all the center of the wheel. Evidently in looking quickly I confused it.

However, I still want to make sure I don't need a new spacer. Wheel specs are below.

OLD WHEELS:
Size: 17x10.5
Offset: +27mm
Backspacing: 6.82
Weight: 24lbs
Lug Pattern: 5x4.5"

NEW WHEELS:
Size: 17x10.5
Offset: +20mm
Backspacing: 6.53
Weight: 24lbs
Lug Pattern: 5x114.3

DELTA:
Offset: 7mm
Backspacing: .29in

My guess would be to compare the back spacing of your current rims to the ones you ordered. The info for the new rims should be listed somewhere.

Easiest way is to go to your local hardware store and buy a ton of washers. Keep adding them until you get the look you want then measure each stack and order the spacer accordingly.

What small town in MI do you live in? I have a ton of spacers you could try if we are close.

The new wheels will be offset outwards 7mm when compared to the old wheels. You will not need any spacers, just make sure the tires don't rub the fender.
