Wondering if I need LCA and the brackets for my setup. The car leaves soft right now (vortech and stock gear/converter) but spins when it shifts at the strip and spins a lot on the street when the boost comes in (4500). I'm running a 275/50/15 MT ET Street S/S, BMR UCA and mount with poly diff bushing and a whiteline rear sway bar. The car is lowered 1 inch as well. Just looking to get it to hook up on the street better. Any input is appreciated.
