I've been using these wheel spacers for the last two years with no issues. For the first 6 months i would periodically retorque the lugs and found no changes.
My real concern was they would loosen, but that fear is gone now. And i love how the rear wheels fit now. Just my experience.
I was planning to convert to rear disk on my burb as part of upgrading the brakes, but a few months ago i installed the wilwood d52 duel piston calipers and a set of rotors from summit racing on the fronts. And holy crap the burb stops so good now I'm leaving the rears alone.
Just throwing it...
Wow Thanks man its nice of you to say that. There's alot of beautiful rigs on this site.
I Spent Two years of nights and weekends In the garage working on it. So a compliment like that feels great.
