alright lets see if i can answer all these at 1 time the kit is from belltech its a 4 inch drop 2inch spindles 2 inch springs 6 in the back flip kit i read the faq on the pinion angle and thought that might have something to do with the wheel hop and loss of power. i didnt shim anything and trust i DESTROYED my flowmaster with my driveshaft i think shes prolly about an inch wide in 1 spot and its supposed to be 2.5 haha not to mention on my 3.5 hour ride back from connecticut with my t-56 the exhaust decided to fall out so i had to hold it up with tow straps all the way home! very annoying sound and on top of that some dick trooper gave me a ticket for 180$ for going like 16 over what a bad day between gas and the ticket i cuda just shipped the frigen tranny and not wasted a whole day! what is the best way to change my angle obviously loosen up the u bolts and move the rear end up or down? what is used to measure it and whats the correct degree for it to be at? thanks guys im really tired of hopping lol oh and i will be putting in an eaton lsd with some 4.56s aswell
