[QUOTE="SCGallo2, post: 15036421, member: 160791"] Yes, lowering the rear suspension changes your pinion angle and affects how your LCAs respond (squat) under hard acceleration. Without LCA relocation brackets, I suspect your LCAs are angled upwards towards the rear of the car. At a minimum, your LCAs should be parallel to the ground with your suspension loaded. For more straight-line traction, your LCAs should be angled slightly downwards towards the rear of the car which adds anti-squat and plants the weight of the car on your rear wheels. For reference, my rear LCA mounting points on the axle assembly are about one inch closer to the ground than the forward LCA mounting points on the body. Relocation brackets will correct the rear suspension geometry, but spring rate and shocks also play an important role in putting the power down. With a full poly bushing rear suspension, my pinion angle is set at -2.0 via an adjustable UCA. My combo works extremely well at my power level and is pretty unique utilizing H&R, BMR, and Maximum Motorsports components. My suspension was not thrown together with a prayer that it would work… I did lots of research and it paid off. [ATTACH]51753.vB[/ATTACH] [ATTACH]51754.vB[/ATTACH] [/QUOTE]
