We have ran the triangulated setup on a 10 second car, running it through a trans brake, with 11 inch slicks with no problems. What I DON'T DO is tighten the lock down bolts after the final instalation this way the threads with a little lubrication will pivot a little, and help with the rubber bushing wear, and there is no way they can come unscrewed. W e have alot of hard runs on the hemi car, and even around town to a lot of shows.
