Does anyone know what size bars were on the R7U cars.

I read that the drivers asked for a smaller rear bar on them and I'm assuming that they probably had a smaller set to begin with than the 36/24s

Also, I'm looking at Prothane bushings and they've got 32/21 designated as 1LE which is the size I have on my car (32/21) - so what's with that? I thought the 1LEs were bigger.

Thanx

 

Higher spring rates compensate for the smaller bars! Besides, It is my understanding that the 34 and 36mm bars are hollow. YUCK! Crack prone and no more torsional stiffness than a solid bar. Lighter though.

I run 32/21!

 

Thanks for the info - that makes sense about the higher rates. I've done a lot of suspension work lately and I thought bigger bars would be needed but after running around some road courses the car seems fine with what it's got.
