Okay, need some advise from yall.I know a guy who I can get a good deal on a roll bar from, but at 6'2'' it looks as if it will impair my comfort quit a bit while not at the track. what do you think about just getting the harness bar. I really need a 5 point harness, but don't want to be uncomfortable when not at the track.

Thanks in advance for your advice.Matt

Honestly, it's going to depend on how much you track the car vs how much you daily it.

Track more: I would honestly get a cage. It'll give you WAY more protection in a roll-over or even a "shiny-side-up" crash.

Daily more: Definately Roll bar. A Harness bar isn't going to do anything more than hold your harnesses down and give you a little more structural rigidity. A roll bar or even a "rear-cage" where only the rear of the car is caged would be ideal.

Just get the roll bar and harness. A full roll cage is a must for strictly a track car but will greatly inhibit your entry and exit for a street car. The 5 point harness can be tucked away when street driving and you can still use the oem set up. Have the harness professionally installed to the floor/frame at the correct points.

I may only be 19, but I've grown up around cars and motorsports lol

Do NOT install your harnesses to the floor! DO NOT! Harnesses need to be at less than a 45* angle to your body.

The harness bracket piece between your legs and the ones on each side of your seats are bolted to the SHEET METAL UNDER THE FLOOR just as in my race car and is approved by the SCCA. (Guess whos going to chime in next!)

I have seen many a cars roll/crash out at the race track. Some with roll bars, some with just the roll hoop. Actually there was a miata that just had a roll hoop in it and crushed the passenger side of the car. Thank GOD there was no passenger and the driver was dazed, white as a sheet, and otherwise ok.

With that being said if you're into serious tracking, I would invest in a roll cage, 6 or 5 point harness, a good race seat with a halo, hans device, and a helmet that will last you a few years. Of course that just depends on how much you are into it.

Funny thing on the miata driver, after rolling the car, he had the rescue crews right the car, and drove the car back to paddock.... he had a garden growing on the inside though

Sorry for getting your panties in a bunch, I was referring to the shoulder harnesses; I guess I should've been a little more specific

OK, well I think most of the people that posted in this are concerned for his safety. If you mount those below a certain degree point, you will compress the discs in your back, and this is how most serious spinal injuries happen. I know sparco sells a harness bar, but still depending on your skill level, it might be worth saving his money up and gettin a roll cage.

I think that's what all of us are concerned for, safety. Roll cages aren't an accessory that you decorate with, they're serious business.

Also, if you're still going to daily your car, and don't like to wear a helmet every day, I seriously reccommend only caging the rear. If yours or a passenger's head hits one of the bars without a helmet, it'll split open like an egg.

But again the problem remains. I am to tall to sit in the front seat, even with the roll bar, and not the full cage. It makes the seat not go all the way back. Anyone have any other suggestions?

Yes, you can get more head room by removeing the oem seat track and bolt the seat directly to the frame under the floor. You may have to have custom brackets made if a seat lowering kit is not available for the oem Z drivers seat. The best way to go though for greater support and safety on the track is to install a racing seat with a fixed position for YOUR height and leg room. The seat is lower without the sliding mechanism and also lighter than stock. You obviously give up the feature of moving the seat back and fourth. A performance shop can mount it to fit you to a tee, unless your really tall!! There are also seats made as a "street and track" version that are easier to get into on a daily basis vs. a track only seat.

, thanks for your help! Now I just need to find a shop in Charleston sc that does that sort of thing. Unfortunately they are all specialty here, i.e. porsche, European in genera, mitsubishi, subaru ect. I have yet to find a place that works on z's, or just Nissan's in general. And you all being Nissan owners already know what our service at the Nissan dealerships is like.
