The front spring rating is 350lbs/inch, the rear are 200. This setup allows for very quick spring changes and home alignments. The front stabilizer bar is located directly above the steering rack and rated at 200 ft/lbs. |

For $100 I obtained 1993 RX7 front brakes/rotors, spindles and axles. The lower control arms are 3/4" square tube steel mounted with adjustable 5/8" heim joints. Custom spindles were fabricated from the '93 Mazda parts that allowed me to keep the 4 piston brake calipers and wheel speed sensors. |

The only original Triumph suspension piece used didn't hold up very well with this setup. The lower control arm broke twice and made us rebuild the front suspension setup again. Fortunately it broke both times at low speed. |

The rack is from a '97 Camaro Z-28, and is the right length to correct for bump-steer. Its got a high ratio rack & pinion, which should make steering fun. |

The rear suspension consists of the original 1987 RX7 rear end subassembly. It has 11" disk brakes, limited slip diff, and is fully independent with coil over Konis in back. The original sway bar was used, and the vertical chassis link was made 'length-adjustable' for rear camber adjustment. The hubs will be replaced by a set with wheel speed sensors, and Delrin bushes will be used. |
