All steel construction except The Custom CNC bushing spacers and Brackets. These TC Rods allow for full on car adjustment of caster!
They work with stock lower control arms or our adjustable units. 22.5MM diameter center rods come Zink plated. 17MM diameter threads Can take High amounts of pressure while staying rigid. Teflon lined rod ends will keep noise to a minimum. Right and left hand threads to make on car adjustments easy. CNC bushing spacers made for the S30 allows easy bolt on installation. Much better than rubber bushing that flex and wear out. Aluminum bushings are totally quiet and never wear out! Designed to be able to withstand hard use by road, rally, and even drift cars. These Tc rods give the driver great handling feeling and response. Zero caster change under high pressure, and full adjustablity of caster. They will greatly improve handling on all S30 z cars especially if lowered.
Can be adjusted 1/2 inch shorter than stock, or 1/2 inch longer than stock TC rods.

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.
