Supermiata Street Alignment

For most street driven Miatas, tire wear is the most important parameter. Excess toe in or out will usually cause more tire wear than somewhat aggressive camber will. The OEM alignment numbers with more rear camber than in front, are designed to induce a bit of understeer.[...] The actual suspension geometry is designed to require greater front than rear camber. The SuperMiata Street Alignment will generally result in no increase in tire wear over OEM and possibly a reduction in tire wear if you occasionally load the tires to maximum cornering forces. In general, this Street alignment is conservative and intended for cars that never slide their tires and spend almost no time at maximum conrnering loads.

NOTE: This alignment will require a slightly larger front sway bar. NB factory, FM or Racing Beat 1" solid bars will work. The RB 1.125 bar is to much for normal street tires (>240 treadwear). The Street Alignment may cause a 100% stock Miata to oversteer, or be too "loose".
