OK. I've done a few driving schools in the past twelve months; mostly autocross related. When I go around a very short oval course (to practice hairpin turns repetively) in one direction for any length of time, my oil pressure light comes on. (I think it comes on only when I'm making repetitive left turns.) So, I need an oil pan baffle. BMP Design sells one for the E30 M3. Where can I find one for my E28 M5? Thanks.
