Wait... I saw some vert guys have 5 point harness and they have slightly different setup with roll cages IIRC. I would wait until get roll cage. Several vert guys have roll cages, so feel free to drop by vert forum and ask questions. I know it's not a coupe or hatchback, but they can give you some basic idea.

4/5/6/7 point harnesses should only be used with a roll bar/roll cage.

Reason#1 is --in the event of a rollover your body cannot slide out of the way--as it can with a 3 pt Factory harness.

I guess it all depends how you will use your car and how safety conscious you are.

Reason #2You want to wrap the harness aroiund the roll bar right behind your seat. The longer the strap ( if you get long ones and bolt to the floor/rear etc) is the straps will stretch in an impact.

reason #3You do not want to mount the shoulder straps to the floor --the angle will be wrong and can result in additional injuries according to the belt manufacturers.

Also --harnesses on the street are not all that "easy" to drive with --unless you like being tightly strapped into the seat ( forget changing the radio station. If you leave the belts loose--you defeat the safety of the harness--there is not a tensioner on the 4/5/6/7 pt harnesses.

hes right about them not being safe without a cage, so i would wait on that.

unless your doing autox and want to be held in better, get a c pillar bar or something and mount the back straps to that, but dont drive it on the street

Good suggestion

Also What you can do for AutoX is install the 5 pts and leave the Factory 3 pt in as well. Then you just wear the 5 pts for AutoX and the Factory stuff for street or track.

YES DO NOT MOUNT ANY LOWER THAN 4" BELOW YOUR SHOULDER LINE!!!!!!!!!!

Could result in spine compression in an accident. Very bad. Get a cage.
