Race seat selection for FD

Just to be clear, I'm not looking for sport seats (ala those with recline mechanism).

I want to be able to shoehorn the seats into another car and don't want to build/mount back supports for both.

I'm thinking to go with the FIA homologated shell type vs. metal frame + back support.

Driver is 6-foot plus an inch or two and weight is around 190 pounds.

I fit in the car with helmet, but just by a smidge.

In addition to the better support while cornering, I'd like to drop an inch or two so I'm well below the Kirk rollbar.
It sounds like custom mounting to the floorboards will be in order?

I know that one needs to take some measurements and that the base size as well as shoulder supports plays into if the seats will fit in the car.

It seems like nothing short of an actual test-fit of both driver to seat and seat to car will result in an ideal selection.

Does anyone have current info on a recent install and have some feedback?

I was looking at the Sparco Evo 2 (I don't fit in the regular Evo) or Corbeau FX1.

I'll also want something reasonably comfortable enough that I can drive the car the track (uh oh, comfortable race seat...oxymoron there, no?)

Oh, and for the "cherry on top" -- I'd like the seats to also fit in an M1 Miata.

Regards,

I have never seen a fd in real life, we dont get them here, but I will buy one next year once i am in the UK.

Sorry, can't offer help with an FIA seat. My Kirkey required cutting out the rear mounts for the seat, sectioning and straightening the trans tunnel to move the seat inboard (to clear my head from the A pillar bar).

Good luck though.

Seems like one of the weak areas for the 3rd Gen. Nobody seems to sell a race seats with mounting brackets for it (at least in the US). Most people seem to make their own. How about one of the 3rd gen shops stepping up and fab'ing some mounts for popular racing seats? Maybe David B. would do it through his widefoot business?

Corbeau Forza or Forza II. They aren't very expensive $220 per seat plus like $60 or $70 each for the seat brackets. Corbeau makes seat brackets for the FD specifically. This is what I am going to do if anyone would buy my tan seats. If anyone has these post some pics and fitment issues if there are any.

I bought some corbeau seat and their brackets for my miata. The fit was not very good. The FD is even more tight inside than a Miata. I wouldn't be surpised if their seats won't fit right even with their brackets.

Personally, I'd go for the stock '01 Spirit R racing seats.

Based on the info in this thread, I purchused the Corbeau Forza and their bracket. I'll let everyone know how it works.

I e-mailed Corbeau, and they say to use the Forza (I specified I wanted something that would fit in the FD and Miata, and would be SCCA legal/FIA homologated).

The FX1 is not yet FIA homologated, although it looks like it may be, come the end of the year.

Looks like I've got to put in a back brace to make it a proper installation in any circumstance.

Spirit R's look interesting, but I'm sure they are going to be costly, and probably not FIA homologated.

I'm still looking, and want to do a trial fit before I plunk down several hundred dollars.

It looks like a large part of the problem are the shoulder "wings" and interference with the door panels. That rules out any composite seats that won't fit because of this reason, although I understand that an AL seat can be modified (ala Kirkey).

New candidate is the Kirkey Road Race Intermediate (50% cheaper than the full road race version, at around $650 each seat with cover) in the $300 range.

You may want to check with Brad Barber. I think he is/was using a Kirkey in his 3rd gen.

I have the Corbeau Forza seats with the Corbeau Brackets in my Miata. They barely fit. I can't slide the seat forward and have too fit too for back for my tastes. If you have long legs this wouldn't be a problem.

Also, unless you are thin the normal size Forza seat is really uncomfortable. The wide model won't fit at all.

I havn't tried fitting the Forza in my '93 RX7 but I don't know... the RX7 is even more tight inside than the Miata.

Man that would stink. If it doesn't fit, I'm shipping it back. I'll give an update after I receive the seat.

Got it tonight. Hopefully I'll install it tomorrow. It has an extra bracket in addition to the replacement base. Hopefully its purpose will be clear when I remove the old seat.

I like my bride zieg IIs... I got a low position seat rail also. Bride themself do not sell the low position seat rail for left side (but for the right), so i had to buy the rail from "arena" (japanese site). I don't have the door panels so the Zieg fits well (actually tight fit). I think zeta IIs fit well with door panels but no low position rails. Bride is now coming out with there 3rd gen of seats.

I'm also about 6'1, so I need to do the same thing. I think a single shell seat bolted to the frame would be the best option, it'll also help with heel-towing!

hahahahah, you got money coming out fo your *** SleepR1? Seriously, those things are like $3000!

Bride makes special racing seats with less of a shoulder bolster on the side by the door just for FD's. While not as much as the custom recaros, they are also $$$!

Corbeau's seem to be the best bang for your buck, unless you feel inclined to source and ship some used racing seats out of a crashed car from Japan. I hear you can get them for like $80 or so over there!

Don't buy the Corbeau Forza. I installed it and it did not fit worth a crap. The bracket was a good fit, but the side of the seat keeps the door from closing unless you allow it to put serious pressure on the trim, and the recline angle offsets the lowered seat to actually give less headroom.

BTW: Corbeau told me this setup would not hit the doors. That is why they will be getting them back next week.

John,

Corbeau did quite a bit of testing for their rails on the 3rd Gen. I believe the final product fits very well (as long as you get a properly sized seat) for the car. I've heard slight complaints about height, but it was quickly remedied by adjusting the amount of washers used.

Granted, the following isn't a racing seat but it gives you an idea about the Corbeau rails:

Yep, rails fit great, but the Forza seat did not.

Updates and commentary on prior conversation I just read this morning:

Trial fitting a Forza
I borrowed a friend's uninstalled seat to try and see what the issues are with fitment.

The seat was a Corbeau Forza:
http://www.corbeau.com/brochure/forza.shtml

This is the same one that almost99 has, which he says doesn't fit.

Rant/Aside
I have yet to see a part for a car that doesn't require a BFH to get it in...what is this bolt-in nonsense??? I might as well EXPECT to engineer EVERYTHING myself, and if it does bolt-in, I'll call it a victory and pop open a beverage while relaxing and reveling in the money I've wasted for a perfectly fitting item and the time I saved

Looks like bolt-in seat brackets won't do the trick...
Continuing on...I didn't have the seat rails, but I'm pretty sire if you fabbed a custom mount bracket, then I believe they would fit. I basically dropped the seat on the floorboards and moved it back/forth and observed the changed dimensions of the seat.

Winged things...
I now see why the shoulder wings are such a problem. In my test-fitting, while seated in the car, the wings didn't rub, but that's not to say the seat was mounted corectly, nor was it at the final elevation above the floorboards (didn't really check to see how much raising the seat impacts this.

But they say it fits!
Cross-referencing to the other thread that Mahjik posted about Chuck Westbrook's A4 installation, I noticed the mention of Spencer Bond, who is the same guy from Corbeau that e-mailed me back when I asked. He told me in a one-line reply to my several paragraphs of requirements, to get the Forza. Mmmkay...

Making vroom-vroom noisesl
I wouldn't buy those seats for track usage. Perhaps it is my frame/size, but as I sat in them, they just don't feel as supportive as the Kirkey Intermediate Race seats, which are really deep, and hold me in much tighter. It was also really weird sitting down so low in the car, BUT, I gained the 2" I want from the top of the rollbar. I guess driving takes a little getting used to, but the good part is that my vision with my "chin up" was right out the center of the window, and the A-pillar mounted boost gauge is squarely in my line of sight.

Comparing seat dimensions
I believe that 22" width of shoulder wings is about the maximum you are going to be able to get into a FD. Any more, especially in a carbon/fiberglass shell-type seat, and you are S.O.L.

The base of the Forza is 20" across, and the seat width is about 16", which is the same as the Kirkey I sat in, but the Kirkey felt more supportive.

Back to the drawing board
I believe that my next move (since the car is now sitting on jackstands for other repairs, ARGH...) is to fabricate mounting structure for the floorboard from courtesy of Home Depot raciing supplies and instead of a "loose" fit of the Forza, attempt a "solid" fit.

I'm also thinking of unbolting the stock sliders and seeing about mounting to an intermediary support to determine if I can retain use of the sliders and retain the extra headroom I gained.

FYI (no pictures yet) - the mount points for the Forza and the stock FD seat are about maybe 1" wider than the FD seat, so you can't just unbolt them and mount them stock sliders to the race seat.

Regards,
--Ashraf

Best and easiest seat install is the Kirkey road race seat (http://www.kirkeyracing.com/page3a.html). Bolts right up to the stock sliders and clears the door panel (barely). Not the lightest seat in the world (~22 lbs) or the most attractive, but very comfortable for my 220 lb. frame.

I'll see if I can dig up some pics.

PICS Gene!!!

The Kirkey looks like the wings are big enough to fly with! If it drops right in the FD my buddy with the Prelude will **** a solid gold brick He wants one sooo bad.

I thought there was no way in Hell that seat would fit. Please note which width you're talking about. (though at 220 lb I hope you need a wider one than my 170)
