Pettit Racing 'Trak Pro' Coilover Suspension

We wanted the Best possible suspension for the RX.  So we made it.

Stage II is well suited for daily driving, spirited driving and most motorsport events as well as occasional track use. They provide a major improvement in stability, handling and cornering grip, but with damper valving precisely matched to spring rates a comfortable quality ride for street and highway driving is retained. They use a 10kg and 8kg (front/rear) spring set (RX7 rates) and have 24 dampening adjustment positions providing ample adjustment range for optimizing grip with different road conditions. Ride quality with Stage II is adjustable, at full soft damping force is less (softer) than stock!!! and since the adjustments are accessible from the top changes to suit conditions and passengers are quick and easy. 

Stage III provides a 20% increase in spring rates over Stages II but is still a good choice for street use and a better choice than Stages II for track use with race tires. 24 dampening adjustment positions provide ample adjustment range for optimizing grip under most any condition and since the adjustments are assessable from the top changes to suit conditions are quick and easy. All Stages feature ride height adjustment from 1” (25.4mm) above stock to 2 (50.8mm) below. All Stages use lightweight billet aluminum for weight savings and CNC machining for precision fit of the main body, threaded adjustment tubes, spring seats and lock nuts as well as the position adjuster locks, Trak Pro Kits are lighter, operate cooler and provide more consistent damping than many popular brands. 

For the ultimate in shock performance, our Trak Pro stage 'Competition' coilovers give incredible track performance with a 15kg / 12kg spring rate (RX7), gas & oil re-fillable chambers for consistent optimal performance combined with ultra fast depressurisation valves give proven track performance.

In order to maintain proper damper stroke with low ride height settings, Trak Pro damper position is adjustable in relation to the lower mount point and this adjustment can be made without removing the unit from the car.  

Our special top mount design places the upper shaft attachment point below the spring seat, this and special hyper rubber bushings eliminate shaft binding caused by angular change as the lower mount moves through its range of travel, also the top mount compliance is adjustable, with higher spring rates there is less range of  travel so the top mounts can be tightened to reduce compliance and improve response.

Pillow ball type mounts common on race cars and most coilover kits have a short life span and are known to loosen in only a few thousand  miles or less transmitting road and tire noise directly into the chassis.  With our hyper rubber mount bushings, compliance is minimized with out the harsh transmission of road and tire noise, so you can expect many years of smooth and quiet performance from Trak Pro dampers.  With no gas to seep from the coilovers,  and as
Trak Pro dampers are rebuildable, this means they will be the last set to purchase for your RX7 or RX8

Trak Pro's high quality materials and superb workmanship is comparable to high end brands costing  fa more, so don't be fooled by low prices, buying direct from Pettit Racing is how you save (no middlemen).
