New To The Site - Harness Question

[jaym]

Hi All. I'm new to the site.

I have a 03 Boxster that I'm using for street and autocross. One thing I'm finding is that I just can't seem to keep my butt in the seat. I'm fighting hard to just keep myself stable in the car. So I'm looking to figure out a good way to put a 4 point harness in the car for relatively cheap. But I also want to be able to put it in easily and take it out when not going to an event. Any ideas would be awesome.

I'm also in the process of building a trailer hitch for the car so I can pull the tire trailer I just finished putting together. I'll post pictures of the project as I make some progress.

Anyway, any info on the a 4 point harness would be much appreciated and I look forward to joining the discussions around here, Thanks!
