seat advice
blakep82 - 11/2/10 at 03:23 PM

i bought some cobra monaco pro seats last year, not entirely happy with them, as they're very tall once the side mounts are on, and the seat belt mounts are all out of place.

race trucks use Kirkey seats. nice, but very expensive and not many

considering GRP, but not entirely sold on them yet....

how are kirkey seats fitted? do they bolt striaght to the floor? my chassis has 2 strips 5mm thick for seats to be bolted to, which are about 25mm above the floor. can't really work out how to get my hands around to bolt them in lol

are GRP seats the same as kirkey in terms of fitting?

i seem to remember somewhere, drawings for making your own ali seats. rorty was it?

Yes.. There are some others that have made similar on here, search might bring them up.

just measured up, and without measuring to the exact mm, the rorty are a better fit than the ones i've got. the top harness holes line up perfect with tube across the back of the seats. looks like these cobra seats will find themselves for sale soon...

i'l have a search, thanks

Hi Blake,

If you send me your dimensions I have a drawing for an Ali seat that could be adapted to fit whatever sizes you need for harness holes and obviously bum width

cheers

ah, cool! cutting on the water jet should be easy enough, but i can't weld aluminium. but if you can, or know someone who can...

have to say, still very much in the 'thinking about it' stage

been looking at ths drawing
http://www.rorty-design.com/files/Rorty%20Basic%20Aluminium%20Seat%20Pattern.pdf

which look about right. top harness holes are almost perfect i think. will need to work out all the sizes properly and get back to you.

I used a similar method of strips 25mm above floor.
I made a seat subframe so it slides into a tab (inacessible side) , then secured using 3 bolts.

Kirkey seats in race cars in North America are bolted to the roll cage, no adjustment, if the truck gets upside down you want more than a production style adjustment system keeping you inside the cage.

so yeah, they would be bolted right to the chassis. no adjustment, not sliders ets. they only movement would be perhaps a thick rubber washer to take away some vibration.

do you know where i might find some photos or drawings of how they're fitted? bolt sizes, washers etc?

kirky seats have one bracket either side of seat and one centre rear. these are bolted to floor then seat screws direct to them. by the way, demon theves have special offer on kirky, check website

Arh but ali seats are flat and not bum friendly...whereas the Triton jobbies are seriously bum friendly....lots of happy rears out there to

they would be once they've got some lovely foam stuck to them

as i said, still trying to decide, but how are GRP ones bolted in? have you got any clear photos of the bottom of them? just to help with fitting and deciding what to go with.

ali seats have flat bottoms, and can be bolted easily. they can also have expanding foam squirted in a bag to make a nicely moulded seat.

grp seats come a little more 'moulded' to shape. but with that look a bit more difficult to fit. they do look comfier though once foam is added

Triton seats are a doddle to fit as have 4 x 8mm steel inserts bonded into the base/second skin...Ed and Em are working on a padding set as well as a complete cover in leather so drop them an email..


alistairolsen - 16/2/10 at 03:12 PM

I wonder what scope there is for cutting down the thickness. Rorty used 2.5mm sheet whereas Kirkey use 2mm.

I suspect the kirkey seats gain what they lose in the material stiffness back in the pressings and rollings. Looking back at some of their earlier seats they are much simpler.

My GRP seats have a flat base with 4 captive nuts - so very easy to mount.

They're also much more comfy than they look.

If you lived near buy id let you come over and sit in mine!

Em and Ed will be at Stoneliegh with the seats on display so folk can try for size and even buy at the show.....

awesome, thanks everyone! a little way off buying any seats at the minute, but i'll have a good think
