Seams the info I got from Racing Beat was incorrect.When I received the new set of springs from them I immediately pulled out the mic to check them. Turns out they measure the same as the Eibach's with a front spring OD of 135mm and a rear spring OD of 116mm. Gonna stay with the Eibach's and return the RB's. Any chance that mhr650 recalls where you picked up your spacers. Seems a very limited market out there unless I get them custom made.$$$$$$$ I think you were right on with using 1/2" spacers. Thanks, Stu

I have never measured my RB springs but I did buy them in 1990, so a lot could have changed since then.

Trying to track down a set of 1/2" wheel spacers. Any suggestions? Apparently the 4 x 110mm is an odd configuration
making it difficult to find the spacers.
