well im sure someone has done this and there is a thread on this but has anyone installed unaversal racing harnesses in there mini cooper s? i have an 02 S and was wonder what might be some mounting point option?

 

Here ya go - Schroth 4pt

IMO the factory 3pt seat belts are adequate for an occasional DE. If the track bug bites you hard, then there's no scrimping on safety - do it right with a properly mounted FIA fixed back seat, roll bar, and either a 5 or 6pt harness.

<edit> You might consider lurking the Racing & Competition section. I'm sure there's a wealth of information on this subject there. - Good luck

 

These are the only alternative unless you go for a harness bar and new seats.
