Starting to think about buying and mounting the harnesses..

Use:

Street and DE's

no cage or roll bar for now.

Lap belt bolts in no problem.

Shoulder harness....

Through rear firewall with reinforcement...

Clip ins or bolt in???? If bolt in then get the slightly bent ones for a little clearance .

What's the down fall on the clip in???? Use with the eyelets.

Been a while so I thought I'd check in....

I've always used clip-in, mainly just for the reduced time/hassle to remove/replace. You will need something to support the shoulder harnesses though. Do you have a harness bar, or something else in mind?

Yes , I do, but I was just reading and wondering about still using?.. Sounds like that's a yes then !

Cool , the snap ins are easier and neater in the long run ,,, thanks

Also note you should cotter pin or safety wire the clip-in latches. This is in most rules I've seen. And just a good idea anyway.
