well guy's, i'm glad the calvert stuff works for you, as for myself i returned it all to calvert for a refund. Put my factory 1974 stock springs w/ slapper bars & ce 3 way adjustable shocks back on and immediately went 1.50 60ft 1st pass off trailer. The car is right back to 1.47-1.49 60ft consistantly all day & night long! The et is also back where it started, and tires wearing even. We're still racing here as long as its 50 degrees, but once the temps drop i will be installing the ladder bars & be done with all the wasted time & money trying to make that crap work! To quote the chassis shop i spoke with "you should'nt have to build a new car to make them work!"
