Prothane bushing brackets - Page 2 - ZR-1 Net Registry Forums

Just over 1.5" in width by 2" tall. I understand what you say by the slots being slotted, but as long as the bolts are properly tight, why would you say they show no quality at all? The company is well respected and this is how all their brackets are made. Thanks for your input too btw!

Jim,

Did you actually put a Vernier on the rear bar to confirm it's diameter? I've seen several claims to 24 and 26 but I've never checked a later '94/'95 car. It might make a difference in some of what I've found through maybe 20 minutes of research. Some very interesting.

I'd like your confirmed dimensions or maybe someone else that has actually measured and not just assumed from the suspension charts.

If the image that was posted was maybe a "will this work/test fit" (wasn't mentioned) then maybe I shouldn't have reacted as I did but I assumed a "finished product" and I'm sorry it ain't.

Post up your dimensions of the rear bar. I believe it's safe to assume that the front is a 26.

Actually I did not verify by measuring, just went by the charts. I'll double check tomorrow. Was just looking at the link Ted posted for Prothane parts and they do show a front bushing/bracket combo. I might just call them tomorrow and verify. I would use the factory bracket but since I have to use Carters relocation bracket, the oem bracket would lower the bar too much. I appreciate you guys input. Been planning to switch over to poly and had the Prothane kit saved on my Amazon site but I guess I jumped the gun before verifying I was getting all I needed. Thanks again!

Measured both front and rear bars per request. 26mm front and rear. Didn't get a chance to call Prothane today but I plan to call and get the brackets they offer for the front bar. I really appreciate you guys help!

FWIW I've gone through a few aftermarket front bars and simply re-used the factory bracket.

I found I had to go smaller in the rear and larger in the front.

PS when installing make sure the bar rotates freely in the bushings before attaching the end links.

Cheers,
- Jeff
