many people dont believe in BBR because of their camshaft claims. there was a big internet war with them and members of other forums about the cams. they made claims, could not readily back them up. lost trust with many. they installed the cams in jonnyz's car (or something like that, different name on all forums). after a bunch of conflicting posts from jonny and BBR, and the comments from the internet world, BBR bought the car fron jonny to presumably stop the negative attention. MONTHS later, no hardcore proof.
sorry, if you want one link PM me. i wont post it in the forum openly.
