With that type of seat, can you still use regular seat belt or you must go to harness?

Harness and roll bar is a minimum in my mind with a one piece bucket seat.

you will still be able to use regular seat belts with out a problem. they may not pass through the bottom hole but they will fit around the seat no issue. if you are looking to just put bucket seats in to replace your current seats and not for racing, you dont need harnesses if you do put them in i am interested to know which ones you used and how hard it was, as i am looking to do the same thing.

Those seats are designed to keep you very vertical in an accident compared to stock seats. I'd want some additional roll over protection if I'm being kept more upright in an accident, hence my suggestion to run a roll bar. Its all about personal risk tolerance. I run one piece buckets with 6 point harnesses and a roll bar. If I was to take any item out of that equation, I'd be more comfortable with the stock setup.

And buckling in takes about 15 seconds when you have done it hundreds of times, it isn't even a concern.

you can probably run the stock seat belts if you wanted to. The new 911 with the optional one piece seats run standard seat belts. The stock seat belt is run through the openings if that makes sense. You would have to unbolt the seat belt at the floor, put it through the opening and bolt it back in place. Same with the female seat belt part. Hope this makes sense, otherwise I will find pics for you. I have seen this in excellence mags.

But I do agree with Chrenan about the seat+harness=good

If your not looking at buckets for competition use, you might want to consider a Schroth 4 pt harness vs. a 5 or 6 pt.

http://www.schrothracing.com/store/Tuning/rallye/rallye-cross

They are DOT approved 4 pt harness systems with little expansion joints that work like a factory shoulder belt eliminating the need for the between the legs anti-sub belt.

The danger with a 5pt in a street car is that you might get lazy and not clip the anti-submarining belt, which makes the harness very likely to hurt you in the event of an impact.

I had some time to find a pic to better explain what I was talking about.

Depending on how aggresive the shoulder area is on the seat you could do this.....


I still think you shoud do a roll bar/cage and harnesses or get a non-fixed bucket seat. Also the roll bar option looks badass!!!

i tried some of the cheaper steel fram seats, its not something i recomend, not at all. Add some bucks and buy a fiber glass chair. I found that Cobra Imola S suited me really nice. I did mountings according to the racing regulations and put it on the stock sliding mounts, really neat. It really adds a new dimension to driving, at least if you drive at the track or auto cross. After i added a OMP lower back pillow it worked nice even for longer trips. If you choose a seat that isnt that extreme, with other words has lower sides it works ok with stock belt.

Why not adda picture of my setup

I put a Sparco Sprint seat in my 924. Coming from a race car background I couldn't stand a standard seat for performance driving. The car is also slowly being converted into a track/race car so I figured I might as well enjoy a nice seat in the meantime. I have one for the passenger side too whenever I get a chance to install it.

Replacing my stock seat for the Sparco...


Modified the factory sliders to mount to the Sparco, then aluminum brackets to bolt it to the floor. This is temporary until I get my real adapters/sliders.



This is how it looks installed in the car... very comfortable although a pain in the ass to get in and out of. Luckily I am 17 years old and 140 lbs so I'm fairly agile.









Seating position...



The seatbelt can and should go through the side harness hole in the seat behind the handbrake, like Porsche does factory in their GT2's/GT3's etc. I am getting a cage and harnesses put in soon so I'm not too concerned for the time being. Hope this helps and let me know if you have any questions.

Use a Schroth harness Rallye-cross harness and a harness bar.

That harness is DOT legal since it allows you to move around a little in the case of a roll-over, etc.

Besides they are slightly easier to put on/off.

Just keep in mind that some sanctioning bodies may not like harnesses without a substrap.
