Trak Pro Coilover Kits
Stage I & II are well suited for daily driving, spirited driving and most motorsport events as well as occasional track use. Both provide a major improvement in stability, handling and cornering grip, but with damper valving precisely matched to spring rates (Stage I) a comfortable quality ride for street and highway driving is retained.
Stage II uses the same spring rates as Stage I but has 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 I & II but is still a good choice for street use and a better choice than Stages I or 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.
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.
Trak Pro's high quality materials and superb workmanship is comparable to high end brands costing more than double, so don't be fooled by low prices, buying direct from Japtrix is how you save (no middlemen).
