Adjustable Rear Upper Control Arms - NA/NB Miata

These rear upper control arms are a bolt-in replacement for the stock arms, and can accept factory rubber bushings or poly bushing like the ones available as an option here.  These proven arms are nearly as light as the factory arms, but also offer easy, incremental camber adjustment independent of the factory eccentric bolts.  This is very beneficial, since those eccentric bolt adjustments also affect toe and thrust angle.  Small tweaks can be made to dial in your setup without affecting other settings.  These arms are also great if you have installed one of our lift kits and need to correct your camber, and/or eliminate the inside of tires rubbing springs.  There's over 8 degrees of adjustment possible in BOTH DIRECTIONS.  Screw the adjustment yoke in and this will move the top of the tires inboard, so if you’re trying to maximize your fender clearance these will help. Each 180 degree turn will change camber by 0.25 degrees, making it easy to make precise, consistent adjustments. There’s also no chance of the setting slipping under load.   Unlike other aftermarket control arms, these are properly contoured to clear the rear subframe. There is no limitation to compression travel.  Stronger than required by a substantial margin.  For 1990-05 Miatas. Sold in pairs.  Available here: RUCA Instructions
