4 pt. Harness

I want to get Sparcos for my car, and will most likely get the sprint seat. My question is: Will four point harnesses such as Sparco or SRR be floor mountable? I don't have a cage, and would rather not get one so I figure the only alternative would be floor mounting. Are they long enough? Thanks.

yes, they will be fine in your car :)

My Sparco 4pts came with big screws, two fit in the back under the back seat (easier if you take your back seats out). I put one waist strap bolt under the oem seat belt clip on the side, and the other one under the rear seat mount on the front seat. Here's a horrible drawing, but hopefully it helps.
