Well yeah, OEM belt on the street. It would look pretty ridiculous to have a full harness when driving to the store for groceries. But you'll be wanting to buckle down at the track, right? I'm sure you're researching this.

Interesting idea- Thanks!

I have really not considered it. This seat should hold me in really well, but I might give it some thought if it is not working the way I want on track. You would be surprised how many people run race belts and even race seats in their daily driver. No thanks.

With re-wiring the side air bag, installing the seat, the new clutch pedal assembly and doing a full tear down and rebuild of my mountain bike, my plate is pretty full right now.

Right. What with your country's 500 anniversary to plan, your bride to murder and Guilder to blame for it... you're swamped.

I gained a full second at autocross just with adding the Schroth belt to my SE-R. I no longer had to think about tensing various parts of my body to hold me in the seat using the OE belts.

I was enlightened when racing LeMons at how well a race seat and a six-point harness held me fast. No flopping, no movement, just me intimately connected to the car. Bring on the G's!

Please I did all that last week while working 60 hours.

What's seats did you have in your SE-R that you added belts to?

My street SE-R used the OE seat.

The LeMons SE-R had a Sparco, I believe.

Glad to hear you finally have your seat on the way! I can confirm that the Bride brackets do indeed include mounts and hardware for the OEM front belt buckles. Keep in mind that if you decide to go with a 4 (or 5) point racing harness then you will still need to add anchor points behind the front seats for the shoulder harnesses... something like a bolt in roll/harness bar behind the front seats... Or you could use extended shoulder harnesses so you can reach the rear seat belt anchor points but this also makes the rear seats basically useless for rear passengers. So if you aren't tracking the car all the time then I would just stick with the OEM belts.

Wow. This is crazy. But if it's something you only clip into place when racing, why not?

Be careful of the angle. Shoulder harness must have less than 45 degree angle or it won't work as designed.

And neither the above nor the Rallye 3 would allowed anywhere near a track by a race organization. Track event and autocross, sure.

45 degrees, harness bar, or cage if you are going to have a harness. Without that the harness can cause unsafe spine compression in an accident, even at low speeds. Most will say against a bar because if you roll the car with a cage it helps prevent head injury (read: head being crushed) that the harness will not allow you to move away from, with a bar there is no protection. It's all about safety, not people being mean, just people trying to save lives when the worst happens. Harnesses are great at what they do, but a little to great and without the supporting mods it is a dangerous thing. My 2 cents.

And for the record, I have a harness bar in my B14 with a 5-point, so obviously I play with fire, but would recommend a cage for worst case scenarios.

I bet the harness made a huge difference in those stock seats, especially in an autocross. Hopefully, the Sparcos are snug enough for me as they are, but only a few track days will tell. Thanks for the idea if the new seat is not enough for me.

Looks like an Evo 8. Very close to 45 degrees on those belts, but not a chance I would want to take.

The seat is supposed to arrive today. I also found out today I have to come in on my day off for 3 hours of Nissan training in the afternoon- when I was planning to install the seat and clutch pedal. I do have Sun-Tue off though so I will probably do the install this weekend.

Yes, very good point... you definitely have to make sure the shoulder harness is at less than a 45° angle. Ideally they would be connected to a roll cage crossbar directly behind the front seats. From the angle of the photo the ones in that pic appear to be less than 45°, but its obviously tough to tell from a photo. I used to run a similar set-up to that pic in my old E36 M3 that I tracked on a regular basis. I ran it at Mid Ohio, Putnam, and IRP and none of those tracks had a problem with the shoulder harnesses being connected to the rear seat belt anchor points... Although that was almost 20 years ago, so things may have changed since then.

Hey look what just arrived! On first impressions the thigh bolsters are definitely snug- especially in the butt, but I think it will be better if I sit a bit more upright. Looking forward to getting this in the car.

2Gornot2g- Did you get 2 allen bolts or 4 with your Bride seat rails to mount the brackets to the seat? For some reason I only got 2 so I need to run to the hardware store to pick up two more. I also noticed that the holes in the front cross rail are too wide to mate up to the Sparco seat so I will need to re-drill one of them. (hole on the left without the shiny silver allen bolt) Oddly enough the holes in the rear cross rail seem to match up ok with the seat??




Quick Reply: Has anyone replaced the front seats in their sedan?
