KW Coilover Kits

To further enhance our chassis tuning packages above, for all serious fast road and track day use we recommend and upgrade to a KW coilover kit. 3 variant kits are available, which can be specified in place of direct replacement spring and damper kits included above. For the ultimate fast road set up our suggestion is the KW Variant 3 kit. For those into trackdays, you will find the ClubSport kit hard to beat. Further details of these kits and springs can be found >>>>> here. <<<<<

Rear Anti Roll Bar and Springs

Rear Adjustable Anti Roll Bar Kit Improving handling is not all about springs and/or dampers. There are other aspects of chassis tuning to consider, such as improving the car's ability corner. This can be hugely improved by fitting a rear anti-roll bar, thus stiffening up the rear end and greatly improving the car's rear end grip, and its road holding, eliminating the car's natural tendency to understeer. Any car fitted with an uprated rear anti-roll bar will feel more 'alive' and fun to drive with much better levels of grip, without compromising on ride comfort. Without doubt this is the best modification that can be done for an Astra chassis.
Rear Anti Roll Bar - Adjustable (ideal for changing settings for Summer and Winter use or for track days) £193.60 Our Price £183.00

Uprated Fast Road and Race Spec DAP Springs

Astra VXR 19" wheels on DAP Springs
Astra VXR on DAP Spec 1 Springs - Click to Enlarge
To improve the ride and road holding of the Astra VXR chassis, for fast road use we recommend the DAP road (Spec 1) springs as offering the ultimate in ride and road holding. These springs work well with the factory VXR damper. The car will benefit from a lowered and improved stance as these springs lower by approximately 25-30mm.

'Race Spec' versions of the DAP springs are also available. Spec 2 are slightly stiffer, sit approximately 10mm lower (about 40mm drop overall) and are further uprated over the road spec springs, designed for trackday use. A reduced weight option is also available for cars with rear trim and seats removed, to help drop the rear on trackday cars. Spec 3 will drop about 50mm all round, but are unsuitable for road use. DAP 'Race Spec' springs are designed to work with a matched uprated damper such as Bilstein B8s. Race Spec springs available to Special Order. £225.00

Eibach Pro Kit Springs

As an alternative to the DAP road springs we offer the Eibach Pro Kit springs. The Eibach Spring Kit lowers by approximately 10-15mm. £161.00 Buy Now Click Here! Eibach Spring Kit

Bilstein Dampers

To enhance the chassis futher a set of B8 dampers are an ideal fast road upgrade especially when matched with a lowered spring set such as DAP Road springs. They will offer improved road holding with good ride comfort from a lowered sports chassis. DAP Race spec springs will need B8 dampers for road and trackday use.

Strut Top Retaining Clips

Strut Top Retaining Clips On Astra H the front damper has plastic Strut Top Retaining Clips (Damper Securing Rings) which snap on around the top of the damper to hold it in place in the suspension turret. These have to be removed when either fitting springs and or dampers. Being plastic they can be prone to snapping. Replacements are inexpensive and worth having around if these jobs are being attempted. 4 required per car (2 halves for each damper)

M32 Quaife ATB Limited Slip Differential

Quaife M32 ATB LSD Click for Full Size Image The Quaife ATB differential for M32 gearboxes. A direct replacement for the standard Vauxhall differential, the Quaife ATB differential transforms your car's performance, making getting the power down onto the road easier, for improved traction and driveability.

Unlike a conventional plate-style limited slip differential, the ATB diff relies on gears rather than clutch plates for its operation. That means it is much smoother in operation. Because of this, the ATB differential never locks harshly with a set pre-load of wheel slip across the driven axle, like a conventional LSD. Rather, the differential automatically biases the torque away from the spinning wheel across the axle, to a constantly varying degree, and never locks.
The Quaife ATB differential has many benefits over a standard open differential, including maximising traction and minimizing wheelspin, eliminating torque steer and snatching in front wheel drive cars compared to conventional LSD units, and a maintenance-free design which retains the standard oil lubrication.

Available for Astra VXR Z20LEH. Also available for Zafira VXR, Corsa VXR (Z16LER), Corsa D SRi 1.6 Turbo (Z16LEL), Astra 1.9 CDTi, Astra H 2.0 Turbo (Z20LEL/Z20LER), Astra H 1.6 Turbo (Z16LET).

Polyurethane Bushes - Road

Attention to the factory rubber bushes is beneficial. They are made to be flexible to some extent to absorb harshness, but as they age the original rubber loses its 'tone' and gets slacker. This allows the suspension system to move relative to the chassis so the car's handling and response become less sharp. The grade of polyurethane used in our uprated bushes is not so hard as to cause undue harshness, however they provide a big improvement over standard and they keep their 'tone' much longer than the original rubber, so the effect lasts longer.
Kits are available as Front and Rear axle sets, or as individual bushes if required.

Unlike the original bushes, Polyurethane Bushes require no special tools to fit and are therefore a relatively easy DIY proposition - or we can fit them for you if you prefer.

Purple Bushes are for road use and have a material shore A harness of 80

Engine Bed/Subframe Bushes

An engineered a solution to replace the factory engine bed/subframe bushes in Astra G/H and Zafria A/B which can be prone to failure and contribute to vague handling. These stiffer engine bed bushes help improve the front end feel of the car especially during turn-in and cornering. By removing the flex in the subframe bushes the handling is improved giving a more positive feel to the front end.

These Front Subframe Bushes feature two polyurethane top-hat style bushes that makes for simple installation and durability. The bushes house a stainless steel sleeve and are supported by zinc coated steel washers at each end for increased support under load.

Poly bushes will be resistant to corrosion and the addition of a stainless steel sleeve should help prevent the bed bolts from seizing into the bushes, which can happen with the factory bushes.

These new bushes replace OE part numbers 90498689, 9223022, 9223023 and 13107328 used across the model ranges.

Suitable for Astra H All Models. 6 required per car.
