what to do
my '99 classic has OME medium springs with an additional 3/4 spacer up front, equalling about 2.5-2.75 lift all over. So far all ii have in is a 1 inch t-case drop. Here is the thing, Ii only get vibes above 80 and about 5% of the time i get decelleration cavitation. I want to go with another inch of spacer and add either 1 inch blocks(which i have, with centerpins) or shackles.......I NEED SOMEONE WHO UNDERSTANDS VIBES BETTER THAN I DO, WHICH IS NOT WELL.....when i lift it another ich, will i get vibes? if so should i shim, stick with the t-case drop, or go to SYE, which would be a last resort. I run canyons with 5.5 backspacing and want to get 31 ssr's on it.
