Mazda RX-7 Coilovers

The first thing to know is which generation you have: the first car from 1978, the FC, or the twin-turbo FD. That sorts our thirteen Mazda RX-7 coilovers into three groups. The FC is the surprise: its BC Racing kit comes in all seven BC series. Six brands make FD kits.

Call 1-800-460-9106 and tell us if you have a first generation car, an FC or an FD.

Animated illustration. It shows where coilovers sit on a car, not your exact kit. Depending on the car and the kit, coilovers can lean forward or back or stand straight up, and some cars use a separate spring and shock in the rear. Your ride height depends on the kit and how it is set up.

Seven BC series, and which RX-7 gets them

BR is on all three; the rest depend on the car.

BR on all three; DS on FC and FD

BR has one 30-click knob per coilover that sets compression and rebound together. DS adds a digressive piston.

ER and ZX on the two later cars

ER is BC's upright shock with an external oil reservoir. Compression and rebound each adjust on their own over 30 clicks. BC calls ZX "most track-tested".

RM, FC only

BC builds RM as an upside-down single-tube shock, mainly for MacPherson strut cars.

HM, FC only

HM combines RM and ER, so compression and rebound adjust separately. BC includes Swift Springs for most cars.

ZR, FC only

BC lists "30-click rebound, 15-click low-speed compression and 12-click high-speed compression". Swift Springs come with most of these kits too.

For Swift Springs on other BC series, use our Custom Build for BC Coilovers option. The first-generation kit name says "Swift Front Only".

Öhlins, TEIN, Fortune Auto, Feal and Ksport

Five more brands make RX-7 kits. Seven of their ten kits are FD RX-7 coilovers. Call 1-800-460-9106 to compare.

Öhlins

Öhlins has one Road & Track kit for the FD, 1993 to 1995.

Every RX-7 coilover kit, by generation

The FD comes first, then the FC, then the first car. The names on the cards come from each kit's product name.

Notes in BC kit names: "Swift Front Only" means the optional Swift spring upgrade is offered for the front springs only on that kit.

Before you buy: what RX-7 owners run into

What RX-7 owners report most often, from owner forums, recalls and service bulletins, and what each point means for your coilovers.

Worn rear pillow ball bushings
FD, 1993 to 1995 (US), 1992 to 2002 overall

FD owners say the six rear pillow ball bushings wear out and are a common cause of rear clunks. MotoIQ's FD project replaced them with genuine Mazda parts because the joints must move in several directions. A pillow ball clunk will survive new coilovers, and loose joints let alignment drift.

Before you install: Jack up each rear wheel and check for play before the install, and replace all six pillow balls together if any are worn.

DTSS rear toe steer
FC, 1986 to 1992

A rotary parts maker says the FC's DTSS rear suspension lets the outside rear wheel toe in up to about one degree in a turn. Grassroots Motorsports forum members chasing FC understeer often say to get rid of the rear steer first. Stiffer coilovers will not remove the joint that steers the rear.

Before you install: If the FC is for autocross or track, decide on a DTSS toe eliminator before the alignment, since it changes how the rear behaves.

The RX-7 story

Mazda's rotary sports car

Mazda USA says its management saw the Wankel rotary as "the most interesting and efficient way" to achieve swift performance.

  3. 1991
    FDIt was first shown in 1991, with two turbos arranged in sequence. Mazda calls it "a no-compromise sports car."

These are three different cars, and each has its own kits on this page.
