What are the largest spacers people are running?

[sdb8100]

I have no particular plan to use spacers, nor have I ever used spacers in any of my other vehicles. I typically choose to find a wheel with the offset/width I'm looking for, but with roadsters having more unique stack up of requirements for wheels (center bore, bolt pattern, stud length, etc) I'm trying to absorb all the information I can from this forum as I find my wheel/tire setup (1969 2000 Roadster).

For those who contribute, it would be great to know the specs of the wheel you're running in addition to the spacer thickness.

Thanks!

On the race car, the spacer is at LEAST an inch, I believe the wheel is 15x7 +0 Tire is 23.3 x 9.5 - 15

Great stuff. Thanks for pics and specs. Were these custom spacers or off the shelf?

Street car spacers are aluminum machined spacers from a tuner shop... I have played with various sizes from 3mm up to 15mm to center the wheels and tires in the fenders, to keep the rubbing to a minimum..

The race car pieces are massive blanks of aluminum. Not sure if custom or bought. But it is also using massive 1/2" studs, would not recommend this big of a spacer on a stockish stud..
