Still tight, it touchs door

 

I'm interested if it lowers the seat and allows the proper tilt (with the butt lower than the knee). Pro2000 fitment would be nice.

 

Before the wheel is reinvented these might be worth a look...

sais they fit Recaro SPG/ SPG3, Sparco Corsa-Rev2, Bride

 

Those bracket look to be as high as the stock ones, but it is hard to tell without measurements.

This is a great thread. I was thinking about having the seat recovered to stock specifications but was quoted $1100 for the pair. For $1100 I would prefer aftermarket seats....

 

Or we can pursue a group buy on the Nielex Intruder: http://www.nielex.jp/page/intruder.html

They look interesting from the point of design.
However, I would think that cross bracing between the two sides are essential in preventing flex of the rail as well as the seat.

 

FIA approved brackets do not have cross rails, but in general they seem to be beefier brackets

 

Now that you mention it, they(Sparco, for example) do not have cross bracing.

 

Just one word on each of these designs: Crash forces are VERY high, racing seats are designed for 30 plus g's (that is 4500 lbs for a typical driver).

IMO, ones life is hanging on a very small piece of steel. In the case of the nielex, a 1/4" steel tab to prevent forward movement and clamping friction of four bolts to prevent vertical and forward movement. In the case of BFGRX7's proposal, clamping friction and the strength of a metal tab cantilevered from one end only.

 

Hello,

Sorry for the delay, my buddy happens to be out of town on family business making it impossible for me to get to the equipment needed to complete this project, but something awesome is happening for him, so I'm really happy for him. I will keep everyone updated.

I'm really liking the Nielex rails for the Rev, unfortunately there isn't an easier way of adjusting the seat other than to unbolt the rear seat anchors. There's also about a .6 of an inch difference in seat width between the Rev 2s and the Pro2000s, though that can be offset by shims.

Julian, I can somewhat see your concern with the concept. If you were sitting in the racing seat and the seat belts were physically attached to the rails, you would have a huge problem. Fortunately, your seat belts are anchored to a harden point on the chassis, with the capability of dispersing most of the energy that your body creates in a head on crash.

My design is not new, rather just a new rendition of a tried and true method of making an adjustable seat a reality. The seat belt plays a major part in this particular design working. With the seatbelt holding your weight in the seat as opposed to letting it fly forward into the windscreen, the seat cannot move forward- the angle of the notching dictates that. Again, my desire is first and foremost a low sitting seat. With that being said, the rails were to be made out of a heavy gauge steel as it is the best (read cheapest) material to handle shearing forces.

If there is to be any design change I would most likely add notching to the forward bolts so as to disperse more of the forward (and somewhat downward) weight transfer that the reinforced seat bolts would endure. I think if that were to change, that would help set your mind at ease.

keep us updated. are you planning on making these for the EVO? will one bracket fit all the sparco side mounted seats?

 

this may save you hassle of making these....

think they would work in our cars? they seems pretty trick:

I'm 6'2". It's like mission impossible to find a seat rail that low enough and fit bigger bucket seat..................

 

No, not really.
You would still have to weld these to the stock rails.

 

but can they be bolted to the floor directly if you wanted to not use a slider?

 

Whatever happened with this? I'd take a set of rails if this project was real ...

 

I would be very interested also...

 

Does anybody have a set of sparco 2000 seats in their FD. Is the fitment the same as the Corsa? I have a seat that I've had over a year and still haven't been able to install.

Somebody out there has to have one.

Thanks

In the same boat as you, I am going to order a set of bride rails (after doing a bit or research) and hope they work, if not sell my pro 2000 and get recaro spg's.
