I want to get the seat rails moved back (bolted further back in the car) or leave them where they are, but extend the rails (weld extra lengths on) so the seat has more travel.

Does anyone know which option would be easier or more feasible? Who can perform this work? I imagine I will need to get it engineered?

This will be for the drivers seat. I've noticed in the R33 the front part of the rails is bolted to a raised section of floor, thus if you moved it back you would have to straighten this piece out. Are there any other things which come to mind?

Has anyone else done this to an R33?

Thanks in advance.

Nope I haven't ever tried this, but I can't see how you would extend the rails, it would have to be moving the rails backwards. Basically you need a good workshop to help you out I'm sure they can extend the mounts to give you an extra bit of room.

Maybe new rails could be fabricated that are longer. I don't know that you could do that at home though.

I'm also 6'5" (nearly 6'6") and I have no real problems with my R34. I need to lay the seat back a bit when wearing a helmet though.

Maybe you could get a race style seat (I think Ducan can get them :)) as this would sit you lower giving you more headroom.

Do those seats need new rails?

Headroom isn't really a problem for me, it's more legroom as most of my height is in my legs.

If my left foot is on the clutch fully depressed then my knee fits comfortably under the steering wheel, otherwise, with my foot just resting on the clutch, my knee does not fit under the wheel and has to sit to the side of the wheel. Obviously, the same applies to the right hand side.

Although a spacer or dished steering wheel could possibly free up some room for my knees, my arms are already close enough to the wheel, so I'd like to actually make the seat further away.

What are the mounts that the seat is bolted to? Are they special reinforced areas of the chassis such that you couldn't simply drill new holes to mount the seat further back?

Thanks for your help guys.

You can't just move the mounting points further backwards, you need to fabricate a mounting plate the rails will go to the plate and the plate will bolt to the seat, you can get a couple of inches here easilly without too much trouble but I wouldn't go past 15cm. You will need this engineered as well.

Yes the mounting points are specially reinforced and new mounting points would need to be as well. But its not that easy because the floow is nothing like flat so the rails need to take that into account.

I'd be careful and ensure that you get any seat mod engineered, I can see popo having a field day on this if you just do a back yard job. Esp. if you also do the passenger seat and are then involved in an accident - or sell the car and it is involved in an accident.

Mine have been moved back on bride rails but on r34 sunroof still no headroom at 6'2" but large build not skinny butt

I'm back about as far as legal you cant be passed a certain point on the B pillar or seatbelts wont work now i need monkey arms cause I have to lay the seats back still ( new seats as well)

Wilshire motor trimmers does seat mods and engineers them in adelaide but wanted to do serious mods to the floor pan mounts etc , 1400 to do 1 drivers seat , just regular mount passenger side and the customer service was lame so didnt use them , still not happy with seating location , going to look at dropping the seat inside the bride rails to gain 40mm or so

Sunroof cars loose 30mm headroom per sales manual , Damn jdm cars with no leg room lol

Funny thing is when I was in japan I saw some tall asians , like 6'5" only thin as a rail , wonder if they cuss the local cars too ?

I am 6 foot and there is around 10 inches clearance from the roof lining to my head, plenty of room, even to slide a helmet on in the car.

Sounds like you need to sell the 34 and upgrade to a V35 or M35 Stagea. :)

I'm 6'8" and actually don't find my 33 GTR too bad (relative to my Datsun 1200 Ute anyway!).

In Melbourne there is a business in Coburg (Franks Engineering) that perform seat modifications and engineers them.

I seem to remember them being pretty good price-wise.

Hmmmm NO

R35 2013 black edition modded to hell YES

My old dodge 4x4 v10 extended cab fit ok haha piece of crap

To fix the problem - ADR rules in bin and do it even better like a rollcage with backing plates thru the floor and add crossbracing for side impacts lol

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
