6 Speed Manual

Simply put – Wavetrac is the only gear diff on the market that does not lose all drive when one axle is unloaded. Axles become unloaded in aggressive driving, track cornering, extremely slick surfaces, etc. It happens more than most people realise.

We won’t go into torque bias ratios or the concept of how torque biasing diffs work at this point. Let’s get to how the Wavetrac affects performance:

For example, you have a conventional gear diff (OEM, Quaife, MF, OBX, Truetrac, Torsen, etc.), you’re on a race track for a track day and during cornering your inside wheel bumps over the curbing. This is normal for track driving. The issue is that for the brief moments your inside tire becomes unloaded when bouncing over curbs, your other wheel is not getting drive – is not putting power down. Gear diffs need load on both axles in order to function. The result on a track (or during aggressive driving) is that there are many times when a normal gear diff supplies only intermittent power to the gripping wheel.

Now, same track with Wavetrac: the patented cam device in the Wavetrac prevents loss of drive when that inside wheel is unloaded. The device is able to generate a load inside the diff (to replace the lost load as it happens) that can then be biased to the gripping wheel – in the end making more consistent power delivery through a corner. That makes the car more predictable, and faster overall.

Other benefits:

• Patented Carbon Fibre Bias Plate for the pinions. All other gear type LSDs run the pinions on the housing, meaning the friction from 0 miles is different to 100 miles, thus effectiveness is reduced over the life of the diff. With the Wavetrac performance is consistent with the Carbon Fibre bias plates!
• Patented Wave Profile eliminates the effect of a near to and zero load condition drive ability issues found in all other gear type ATB LSDs.
• ARP Bolts used throughout for superior faster reliability.
• 9310 steel gears run in billet or forged steel bodies.
• Manufactured & Designed in the USA

WAVETRAC: Smooth is Fast

The beauty of the Wavetrac is that it is ideally suited to high performance road cars that see track use. It is very strong, yet transparent to both driver and traction control electronics during regular driving. On the track or in spirited road use, it provides drive to both wheels without the handling issues that traditional clutch type diffs create (there is no tendency to push/understeer with a Wavetrac).

The Wavetrac outperforms other gear type differentials because unlike them, it won’t lose drive when one axle is unloaded (which happens more often than you’d think).

Lastly, one of the most underrated benefits of the Wavetrac is its smooth delivery of power near the limit. Its patented design makes for a very predictable, smooth addition of power when you need it most – when things are at their limits: on the edge of traction mid-corner and using throttle to keep it there; or coming into a corner a little hot, but quickly back on it to maintain exit speed…

These situations are often subjective to the driver, but the benefit can be felt. The Wavetrac makes you faster because it lets you drive with confidence. Smooth is fast.

Lowering Levels:
Front: 5-25mm
Rear: 15mm

A KW Height Adjustable Coilover Conversion Spring Kit is the ideal solution if you want to keep your cars stock dampers but still enjoy the benefits of adjustable lowering like you would get with coilovers.

Whereas a normal spring kit generally offers a fixed amount of lowering, KW’s coilover spring kit comes with it’s own adjustable spring seats/perches which replace the fixed factory items allowing the lowering level of each to be finetuned individually.

Taking only a little more time to install than a lowering spring kit (perhaps an extra hour to finetune the lowering amount) this kit replaces the stock, non-adjustable spring seats/perches and generally includes springs precisely matched to the factory dampers, adjustable perches/seats, bump-stops and dust-covers.

Unlike conventional coilovers which replace the adaptive dampers or an expensive electronically adaptable coilover set-up this upgrade goes straight onto the factory adaptive dampers.

Many of the springs provided are progressive rate. Progressive rate springs are ideal for fast road use. The spring is softer in the middle so for small compressions (e.g. small bumps and imperfections in the road) they remain compliant but firms up as it compresses further to provide excellent body control and taut, predictable handling through corners. KW specifically select the best spring for each application on a kit-by-kit basis.

Each kit is carefully tuned to match the factory dampers on the car it is intended for. These are proving to be a popular upgrade on high-end performance models with adaptive damping from the factory.

As with anything KW make, these springs are manufactured to the highest standards. Each part number is individually TUV certified (copy of certificate can be supplied upon request by us or KW) for peace of mind and to meet local legal requirements. Springs are manufactured from Silicum Steel with a tough weather resistant coating.
