Hella DynaBeam Headlights - Astra H.

Upgrade headlight set for Vauxhall Astra H (03/04 - ), with DynaBeam curve light. For RHD.

Dynabeam Lights - Astra H A technological breakthrough in terms of safe and dynamic driving through bends. A sensor patented by Hella takes but split seconds to measure the lateral acceleration and yaw rate, computes these readings, and actuates the DynaBeam headlight to output the right light for the right speed and direction. The entire headlight module assembly is able to swivel by up to 15 degrees.

The basis of the dynamic directional headlights is a 70mm Bi-halogen projection module which is equipped with a powerful H7 halogen bulb. Bi-halogen means low beam and high beam from a single projection module, such that the advantages of improved bend illumination are also available when driving using
high beam. They provide almost double the width of illumination of the bend compared to conventional lighting offering much better visibility, and they will remove the fried egg indicator appearance of the factory non Xenon light unit.

This headlamp works just like the Original Equipment AFL (Adaptive Forward Lighting) Factory Xenon lights with is swivel beams. It also incorporates the same reflector and projector  light units as the "OE" xenon light so if you where to then fit an after market xenon (HID) system you will get the same light intensity and focused & controlled beam pattern generated by the projector beam unit.

The kit is sourced for the UK Right Hand Drive market directly with Hella and includes: Both Right Hand Drive headlights and all bulbs, full plug and play wiring loom, headlight AFL ecu and fitting instructions. Upgrade Option - Silver Indicator Bulbs.

The retail price is of the kit is £1060, however we have negotiated a special price with Hella on the first 5 UK Right Hand Drive kits at £695 inc vat. Buy Now Click Here!

M32 Quaife ATB Limited Slip Differential

Quaife M32 ATB LSD Click for Full Size Image  Now available from Courtenay Sport, 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 now for Astra VXR (Z20LEH), Astra 1.9 CDTi, Astra H 2.0 Turbo (Z20LEL/Z20LER), Astra H 1.6 Turbo (Z16LET), Corsa VXR (Z16LER), Corsa D SRi 1.6 Turbo (Z16LEL)

Retail Price - £670 including VAT. Introductory Offers Available - Call for details. In House Fitting Also Available.

Stephan's Speedster Turbo breaks the 10 second barrier!

Stephan Klasen, our mapping engineer, set himself a target to build an Opel Speedster turbo capable of running a quarter of a mile in less than 10 seconds. He has come close before at a fraction over 10 seconds.

On Saturday the 1st of September he achieved his goal, after finding another 17 bhp from an already very powerful Z20LET engine. With some tweaks to the cam timing and increasing the air flow meter to a 100mm version, further mapping resulted in 602 BHP.

The 1/4 mile time was 9.969 seconds at 143.77 mph. He also recorded an 1/8 mile time of 6.58 seconds at 116.00 mph

See the video here.........

Congratulations Stephan. Keep up the good work.
