VX220 Tuning

Recently in for some fairly extensive modifications were this brace of VX220s.

The 2.2 underwent a Stage 1 supercharger conversion, an uprated fuel pump with 48L alloy fuel tank and rolling road set up.

The turbo model had a chargecooler system fitted, along with uprated fuel pump and uprated clutch, 80mm air flow meter and 495cc injectors, followed by a full rolling road mapping session, to complement the already fitted VXR turbo and full exhaust system.

KW Clubsport Coilover Kit for Astra H VXR

We have recently fitted a KW Clubsport Coilover kit to our Astra H VXR track car, which was running a Bilstein B8 set up with Courtenay DAP Race Spec springs.

The Clubsport kit is the prefered choice for a track biased suspension for a car that is used predominantly on track (more than it is on the road) and is the next step up from the excellent KW V3 coilover kit, which is an ideal fast road kit also suitable for light light trackday use.

Full stainless steel dampers, height adjustable springs with helper springs, solid top mounts on the front struts and 2 way damper adjustment on both the front and the rear dampers for compression and rebound adjustment to fine tune the set up.

A reminder, this is the kit as supplied:

KW Clubsport coilovers were developed for customers who demand a better handling car when participating in track day events, but also require a setup that is still acceptable for road use such as to and from trackdays. The Clubsport kit was specifically designed for the Nordschleife using track day tires. The independently adjustable rebound and compression damping technology allow the suspension setup according to the vehicle load, tire characteristics and different track conditions. KW Clubsport meets every demand regarding a coilover for on road use but more importantly track use.

Here are some pictures of the fitted kit:

We prepared a second subframe and fitted the uprated bushes to it prior to fitting it to one of our track day cars.
