79-85 Racing Suspension

Camber/Caster Upper Spring Perch
	These racing camber/caster assemblies allow maximum negative camber adjustability within the stock strut tower of the chassis. Minor cutting required to allow the maximum camber range of the adjustment slots. Caster adjustability is also featured. Torrington style bearings with hardened thrust washers are utilized in the upper spring perch-to-plate contact areas. Designed to use the 2 1/2" I.D. springs as listed below. Note: The upper bearing is 5/8" id. Some shocks/struts (including stock) require modifying the top to fit in the bearing. For racing 81-85 front struts, use Tokico BZ 1086's found later in this section. These do not require modifying.
Fits all 79-92 RX7's Pair is part number R-CAMBER-RX7

2 1/2" I.D. RACING SPRINGS
	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 --- (These MUST be used with the perches and camber/caster plates listed above.)
Part Number is RACESPRING-1F (Front, 2 required)

	TOKICO "Improved Touring" Adjustable Front Struts (81-85)
	These struts are recommended for 79-85 ITA, ITS, Pro7, RX, and similar cars. (The 79-80's need to be updated to (81-85). The upper shaft diameter fits the spherical bearing of the camber/caster plates without any modification - just please remember to request the plates with the extra bushing. They are also stiffer than the BZ1069's found in the suspension section. Note: these will NOT fit original equipment strut tops - they are specifically for the camber/caster plate applications.
	Part Number H-BZ1086 (two required)

Rear Springs for 79-85
	These springs are specially designed to fit the rear of 79-85 RX7's. The outside and inside diameters are the same as the original springs, which allows them to fit the stock upper (chassis) and lower (on axle housing) spring perches. The bottom coils are "Dead-Wound", which means they do not affect the spring rate. This allows cutting off however many you don't need, in order to bring the ride height down as necessary.

WHEEL STUDS for 79-85 (12A)
			These "screw-in" studs are 2 1/4" long, with approximately 1 3/4" available for wheel bolting, with the correct 12x1.50 thread. They are needed when using various after-market wheels, or replacing the stock lug nuts that have integral studs. We do not supply nuts to fit them, as there are far too many styles needed to fit all the different wheels.

79-85 Rear Lower Suspension Links
We have found that the rear suspension on these cars needs to have soft rubber bushings in order to move properly. Replacing the bushings in these links with urethane or heim joints is not functional. In addition, as the rubber in these stock links ages, it becomes harder. If you are trying to make the car handle consistently, we recommend replacing all four links with new Mazda links. The other problem area, especially on race cars, is the watts link pivot bracket. The studs welded into the bracket have a tendency to break off. We have developed a bracket that puts the studs in double shear and greatly reduces this type of failure.

Heavy Duty Replacement Idler Arm
	The idler arm bushings are prone to failure on 79-85 RX7's due in part to the extream exhaust heat which passes very close to the idler arm. This problem is exaggerated in racing applications. These replacement idler arms solve this problem by using ball joints rather than bushings.

Polyurethane Bushings
Polyurethane bushings are an improvemant up from original equipment rubber bushings due to their firmness. They do not require nearly as much compression, compared to stock bushings, before they let the actual suspension begin to function.
