This unique camber and caster adjustable front lower control arm achieves massive angle clearance because of the S shaped caster arm. Track width is adjustable between 1 and 3 inches per side wider than the OEM FLCA while the caster arm maintains the same tire clearance at any track width because of the multiple mounting locations in the FLCA. The fixed length caster arm is caster adjustable using the spherical bearing side spacers. With this much adjustment in this very strong FLCA. the thin and unreliable slotted mazda subframe pickup points can be locked out and reinforced with the plate set we sell separately. Multiple mounting points for the coilover and sway bar link offer even more versatility. The bump stop is made specifically for our forged knuckle, and the (40mm width 18ID bearing side spacers included for this arm's) coilover mount side spacing is only for our pro coilover's 18id bearing, otherwise the 50mm bushing insert in most coilovers must get cut down 5mm on each side to fit.
