1970T wheel/tire/spacer setup...

[Ryan1938]

OK guys, I've read a ton of threads on the subject, but wanted a sanity check before I pulled the trigger.

Essentially, the car is a 1970 911T (no flares) and I wanna run Group 4 Torq Thrusts - 15x7R rear and 15x6 fronts. On top of that, I'm hoping to run Avon CRZ66 rubber - 185/70/15 front and 215/60/15 rear.

If my research is correct, the 215 Avon is gonna be a tight fit on the rear and require a 15mm spacer.

Given that, two questions:

1. Is the 15mm spacer thing pretty well known at this point on these cars? Meaning, go ahead and order them to be ready for the rolling stock? Or has it varied from car to car and I should wait to get the wheels and tires, measure, and then order?

2. Who makes the best wheel spacers for such an endeavor?

Thanks a ton guys!
