This is a new car, and I'm trying to figure out the best harness arangement.

I have a Kirkey Road Race Intermediate seat and Simpson Camlock pull-up belts. The seat is about two inches from the package shelf wall.

When I test fit the belts, it appears that the buckles are right at the holes in the seat. The buckle tabs are pressing on the top side of the hole in the seat. When I try to tighten the lap belts, the slight preasure on the buckle tabs prevents the belts from tighenting.

I think that I can enlarge the holes in the seat by about 1/2-3/4" and the buckle tabs will no longer be pressed by the seat. But I'm hesitant to cut into a brand new $300 seat ...

Does anyone have any experience with this situation? Is it a bad idea to cut the seat? With pull-up belts, where should the buckle be, inside the seat, outside the seat, or right in the holes?

When I manually make sure that the tabs on the buckles stay outside the seat, I can really get the belts nice and tight.

Thoughts? Also, with all due respect, I'd like to hear from experience, not theory.

Thanks!
