i have a 94 4 door sidekick and am lifting it i might be going with the rocky steady 4.5"  lift.  anything bad about these?  Or what will be better?

Nothings really bad bout them...just most people will say go wit calmini. Me personally i would go wit the rock steady only cause im on a cheap budget like you cant believe 

from what ive heard, the Rocksteady kit is pretty good. ive got the 3" Calmini lift, and i love it. the ride is a little rough, but its tolerable. the OME kit is also a great product, but i havent seen a kit offering more than a 2" lift. or you could always make your own lift.

I find it pricy for what it is, there are other kits out there that don't use coil spacers as part of the lift, and comparable pricing and ride. Look into the OME 2"; BDS Suspension 2"; Boondox 2.5". Combine any of those with a 2" or 3" body lift from BDS, Sky, RRO, Calmini or home made 3".  I think the best is a mixture of a few of them rather than a kit, if the money is there then OME struts and shocks would be at the top of my list.  For my personal taste, I'd like to do the boondox 2.5" springs & diff lowering brackets, with OME struts and shocks, and a BDS 2" body lift(BDS has the most complete 2" body lift kit, and is great if you're using stock bumpers)
