Greetings!
I purchased the L&N Engineering .5 quart sump extension kit and installed it on my 2001 Boxster 'S', which I use for the occasional autocross. Not too difficult a job for the extra peace of mind. Instructions are straightforward and workmanship and quality of the part is excellent. Helps to have a Dremel or similar tool to enlarge the oil sump baffle openings. Once installed, oil pan does not protrude far enough to worry about damage from normal size curbs or driveways. Hopefully, the oil pump won't suck any air while I'm tossing my car around on the course.
