Editing Brake discs (section)

===Vauxhall VX220/Opel Speedster===

VX/Speedster discs are also 288mm as on the S2, but there are some differences:

* hubs are 5 stud
* use a bigger center bore
* use a slightly different offset (about 1 to 2mm) because the VX220 uses a different bearing pack. (uprights are identical to the S2 though)
* are almost the same thickness as S2 discs (25mm vs. 26mm), but have a much thicker surface and as a result a much smaller air-gap between the disc surfaces.

The last point makes the VX220 discs significantly heavier than S2 discs (around 750G to 1 Kg each).

The thicker surface should give them a little more heat capacity, but also makes it more difficult for them to shed the heat again.

VX220 discs are actually taken from existing GM cars (Vauxhall/SAAB), eg. Vauxhall Vectra V6 2.5 front discs, and as such they can be obtain from many regular car-parts stores are very low prices.
