Adjustable Lower Spring Perch

These adjustable height lower spring perches simply drop over the strut or shock housing and rest on the original lower spring perch that is part of the strut/shock housing. SCCA "Improved Touring" Legal! This greatly simplifies adding ride-height adjustability to your RX7. These require the use of 2 ½" I.D. racing springs, the camber/caster plate assembly for the front, and the upper rear spring perch listed below.

2 ½" I.D. RACING SPRINGS

RACESPRING-2F Front 86-92 (2 required)

These RACING SPRINGS are the "best" starting rates for the applications listed. Other rates are available, but we recommend starting with the listed ones, and see if the car needs any changes -- remember that all suspension is inter-related. You can make the whole car stiffer (buy 4 or 8 more springs), soften the whole car (buy 4 or 8 more springs), change one end only (buy 2 more at least) almost indefinitely -- and then it's all different at the next track --------- Welcome to RACING ---

Rear Camber Adjusting for 86-92

The rear camber can be adjusted in different manners on the 86-92's. By pulling up or pushing down on the rear subframe where the original equipment vertical link is located, negative camber can be reduced or increased. This method changes both wheels an equal amount. Part #14008 has threads in the center of the assembly and requires removing the bolt from one end of the link to adjust the length. The subframe is then pushed or pulled to align with the new length and re-install the bolt. Part Number 04-7421-0000 allows adjustment without having to remove the link by incorporating heim joints, left and right-hand threads, with jam nuts. One link required per car.

Part Number: 14008

Part Number: 04-7421-0000

These are really trick pieces -They allow camber adjusting on EACH rear wheel.

These will take out about as much of the negative camber in the rear wheels as is "mechanically" possible. The only way to get more of it out requires a lot of cutting, grinding, and welding.
