Seats For R33 Gtr - Experiences

[WRRR]

Guys

I am having real trouble finding a seat/rail combination that will fit my car and still leave me with some room for a helmet.

Std GTR seats - not enought support need to lay back a long way to get helmet clearance, SR3 Recaros - uncomfortably tight around the thighs, OMP recliners - almost need to lay down to get head clearance (ok with no helmet).

Can anyone enlighten me with seat/rail combos that actually fit and give you some head room. Would prefer to stay with some form of rail to allow for/aft adjustment but not sure if its possible. All suggestions/experiences appreciated.

Help!!!

Best bet is steering wheel spacer and jsut recline the seat back...its about the only thing you can do as the std GTR seats sit pretty damn low. Only other thing is getting rid of the rails and bolting to the floor, but again std GTR seats a good things for height

I had the same problem, being 6'5" there wasn't sufficient room for helmet. To fix the problem I fitted a Racetech fixed bucket seat with a Bride LowMax seat rail. Seating position was much better and enough headroom for helmet. I also had a Sparco steering wheel spacer and quick release to bring the steering wheel closer.

Hope that helps...

Thanks for the replies. Bride low max rail may be a good tip. I have been using either standard or RX rails and they have pushed me too high.

I think I must prefer a more upright driving position as I am only 6' (shite Jack how do you cope)

I have been looking at one of the new Works Bell spacer/tilt units as it may help with the wheel/leg balance.

I have been trying to avoid swapping seats for track to road but it is looking like it may be necessary.

Thanks so far guys. This forum has been really good to me and I do appreciate it - learning the hard way all the time is too painfull and expensive.

Cheers

HEADROOM ISSUES ON OUR TIME ATTACK CAR

We're having a similar problem with headroom on our time attack project car. We're lowering the roofline to cut down on frontal area, but of course that reduces headroom with the seat in a more upright position. The photos above are of the same short windscreen and roof which we'll be running.

The post with photos about our headroom issues with the lowered roofline is here ...

Lowering seats and custom seat mounts is definitely the kind of thing that needs to done by a professional engineer especially if it is going to be road registered. The seat mounting system needs to be absolutely rock solid.

So what we're looking at is reclining the seat (by using a side mount seat) and mounting it as low as possible, but with the side mounts attached to rails for fore and aft adjustment.

The seat we are looking at is the Recaro Pro Racer HANS SPA - full carbon kevlar jobs which only weigh 4.5kg.

We're looking at using some late 70's model 911 seat rails which are very very compact and almost flat in cross section, so they will allow us to get the seat very low since we don't have the added height of a thick seat rail to deal with. From memory they are less than 10 mm thick but i'd have to check the exact thickness. We have a trade account with Porsche if you want a set - as far as I know Porsche still have new stock of them.

The issue on our time attack car is the width between the stock mountings for the factory seats - we'd prefer not to cut them out, so we want a seat that can fit between the factory mountings so the bottom of the seat sits lower than the factory mounting points.

If you look at this photo of a 911 seat setup, you can see how there is quite a bit of height between where the seat rails attach and the floor - we're trying to get back some of that space ...

So our thinking is that we'll attach Porsche or Recaro low profile rails to the stock seat attachmentment points on the chassis, then get a U shaped cradle made up that bolts onto the top of those rails with the bottom of the U as close to the floor as possible. The seat's adjustable side mounts will then attach to the cradle, and then the seat attaches to the side mounts.

Or we may attach the runners to the U shaped cradle under the seat, but we think that by attaching the runners to the cradle then the seat on top the runners, the height of the seat would be higher since the runners move the seat upwards by the thickness of the runners - whereas if we attach the runners to the factory attachment points on the chassis, then attach the cradle to the runners and the seat to the cradle, then we can cancel out the thickness of the runners by designer a deeper U-shaped cradle - the depth of the cradle can then cancel out the height of the runners.

That way we end up with both fore and aft adjustment on the sliders, and angle adjustment of the racing seat on the side mounts, so we can tweak the seat position as much as we want, and get the bottom of the seat as close to the floor as we can safely get it.

Here's a photo of a Porsche seat rail ...

Or Recaro also do a nice low profile seat rail - here's a photo of one ...

Thanks for the comprehensive reply. I have been looking at the rapfix II (maybe I will win your promo - that would make it easy) but is there any feedback on legality for the road?

Reality is my car is it is not a pure track car and needs to stay road registered (and as close to fully legal as possible).

The floor plan on the GTR makes any flat mount difficult but I will compare your pics and see if a modded porca unit will work.

If you're 6' you should have no issues with headroom. Get some Bride low max seat rails and you'll be set. Just speak to a sponsor like RMS and ask them for the lowest Bride rails available for whichever seat you want (side or bottom mount). I'm as tall as Jack and I fit into my 180sx and his GT-R without an issue.

You'd have to check with your local authorities regarding the legality of using of quick releases on road cars on public roads.
