From the factory subframes are installed quickly so as not to slow down the production line. This is done with ill fitting bolts that leaves an inconsistent mating surface between vital components. Mazda RX-7 [FD3S] Subframe Collars install between the subframe and the chassis and take up the slack left by these undersized bolts. The result is improved handling, more consistent camber settings, less vibration and improved braking.
- Front & Rear Set
- Easy Install Requires Lowering of Subframe (NOT Removal)
