Caltrac Tuning Info LOOK HERE

Has anyone tried the
"ASSASSIN" TRACTION BARS
made by Smith Racecraft, I bought a set for my 1970 Dart 408 they are very similar to the Caltrac's but are way more tuneable, Just wondering if anyone has any advice for me ..... Thanks !
I own a set, I'm working on getting my minitubs and springs relocated. I'm highly doubtful I'll have anything to tell before you get yours on but yes, they're a quality part.
