i just bought a 91 mr2. the guy i bought it from told me it had brakes from a turbo model. so i bought rotors for a turbo model and the calipers didnt fit, the rotor interfered with the fit. now that i dont know what i have i need to ask will the turbo spindle assembly on the non turbo car? will the turbo calipers fit the non turbo spindle assembly? the calipers that are on the car are two piston calipers, i need to know how to tell the difference between the two different calipers for the turbo and nonturbo models. i figure if i already have the rotors for an upgrade i might as well upgrade. thanks for any help
