Billet Aluminum Front Lower Control Arms for 240z 260z 280z LCA datsun s30

These arms allow for full adjustment of the suspension geometry without having to remove any parts. They allow for on car adjustment of LAC length (camber) and the pick-up points can be raised for better geometry. Length adjustable from .25" below factory to 1.5" over factory.Constructed of high grade T6061 aluminum. These control arms are extremely strong compared to factory parts. They will take the hard use of rally race and all aggressive driving conditions. Can be used with stock TC rod or our upgraded Adjustable TC rods.

Each arm weights 2.4 pounds. Techno toy tuning arms are 4 pounds each. Almost double the amount of unsprung weight compared to ours.

Based on our testing here are some suggested settings.

Caveat Emptor: These are starting points for you and your car. Be ready and willing to change them based on your preferences and local conditions. These alignment settings might be a bit tricky in the rain and even trickier in snow or ice. Your tires will wear a bit faster then the stock alignment settings.
