Whiteline Black Box Handling Bias Modifier - GM/Opel Astra Mk4 TS 99-04

Unfortunately the system forces a particular handling or chassis control model on the driver and that generally means understeer, always understeer and sometimes in big amounts regardless of what you do with changing mechanical components. To make matters worse, the ideal “handling model” designed by the electronic boffins at the car company changes from make to make to model so it’s a moving target. Being a good innovation, its built in safety bias means it works with the ABS which makes it difficult to turn off. And don’t be fooled by the fitment of a DSC/ESP off switch on the dash, in most cases it doesn’t actually turn off the DSC, just dumbs it down. But apart from that, DSC/ESP can actually work for you even while racing so what if you could simply tune it........
Enter the Whiteline Blackbox. Our design lets you actually tune the factory DSC/ESP system. Use a simple knob to tune the understeer or overtseer bias in the cabin, program the amount of intervention or simply turn it off completely while leaving the ABS fully functional. This patented, world first is the only way we know to tune the factory stability control system to suit your preference, setup or motorsport event. You can see the system working on this YouTube clip.
