i got mine installed.. lowered about 3-3.5 inches and the rear is only neg 0.2deg on both sides.. so it worked out perfect.

the front is maxed out and its sitting at neg 1.2 deg

cant complain !! better than the neg 3.5-4deg i was running before.. the kit will save me 3 tyre swaps a year for the cost of 1 tyre swap
