I reply to every thread Posted January 24, 2002 Share Posted January 24, 2002 I have: 2X Carbon Kevlar Tillets 1X Tillet static mounting set 1X Remains of sliding mounting set from leather seat (Pre "S" type) Caterham are all out of sliding mounting sets for Tillets & will be for a few weeks to come. Caterham parts dept were of the opinion that you could adapt the leather seat slider for the Tillet. They may well be right. Problem is that the distance between the mounting holes across the Tillet seat base, that is side to side rather than front to back is different to the leathers so the leather mounting points in the chassis cannot be used. The static set seems to be the same. Are Tillet mounts usually bolted straight through the floor rather than through the chassis. Seems a little precarious to me. Even with large washers wouldn't the mountings pull through the floor in the event of a shunt? Then again if you went in that hard you'd probably have plenty else to worry about! I'm pretty convinced that I can use the leather sliders by bolting through the floor but is that what others do or is there another solution?

julians Posted January 24, 2002 Share Posted January 24, 2002 The tillets are bolted straight through the floor, however caterham sell reinforcing channels that rivet to the underside of the floor to beef it up a bit. I think you'd probably be alright with a couple of big washers, as even in a shunt its not the seat taking any force, it'll be your harnesses which are bolted to the chassis (unless you go in backwards, even then I dont think that the reinforcing channels would stop the seat being up rooted).

New Barbie Posted January 24, 2002 Share Posted January 24, 2002 Matthew Managed to find another one then, well done. Just lose the heater and screen now and what's more, you'll be a man my son. The seats should have ally fixing brackets which bolt to the bottom and these are then bolted straight through the floor. There are large washers for the underside of the car. I don't have a re-inforcing strip for under the car, I don't think Phil Lee did either for his R500 as we were talking about it on Sunday. On the driver's side, you use large black spacing washers to get the height and angle required for the driving position and you actually need quite a few to get it right. The sliding runner to allow front to back changes is cheap and nasty and if the leather seat one can be fettled to do, I'd go with that. Make sure you get the harness fixed underneath before the seat is on if you have six point as it's awkward to adjust it with the seat in. Have both your seats got Tillet on them then ?

I reply to every thread Posted January 24, 2002 Author Share Posted January 24, 2002 Nope - Tillet were watertight on their trading agreement with Caterham - which is fair enough I 'spose. So one Caterham & one Tillet. I'll bolt to the floor then. Still a bit worried about ending up with an arse shaped dent in my floor pan though! The fact I have a heater is probably what allows me to have a Seven. Heater disapears - So does tolerance. 4 or 5 Kgs is a small price to pay.

New Barbie Posted January 24, 2002 Share Posted January 24, 2002 Fat Arnie has had his mounted on the floor and got away with it. His floor is carbon fibre so in any prang it would break along the weave and form nice serrated edges to cut up the poor unfortunate in the (knowing my luck) passenger seat.

John Posted January 24, 2002 Share Posted January 24, 2002 Why not brace the floor with some thin plywood (approx 3mm) in an area under the seat so remains unseen? Could always be painted black I suppose. John Link to comment Share on other sites More sharing options...

EFA Posted January 24, 2002 Share Posted January 24, 2002 Count, You do have reinforcing channels. If you had actually put some of your car together yourself you would know this. As your mechanic (but implying no subservancy, just sympathy) I feel qualified to state this......... Matthew, The pass seat in addition uses extruded ally square section supports, and the drivers seat uses runners to provide adjustment for the vertically challenged. You could bolt the seats direct to the floor, but the runners or ally extrusions spread your weight over a much larger area than a few large washers and the flat faces of the seat underside would. in the real world this is impractical as you need to lift the fornt of the seat using the plastic spacers to provide under thigh support. Without this your legs go numb after an hours driving and you get a small problem being able to find the pedals!! Particularly annoying if you are hurriedly looking for the brakes at the time..... If you bought a new seat it should come with runners or the ally extrusions. Fitting these seats is a bitch, but with the right bits they are the best option.

The Stig Posted January 24, 2002 Share Posted January 24, 2002 The new style heater weighs 2.6kgs with water in it! The new runners looked remarkably like the old ones off the new leather seats when we fitted a friend GRP Tillet seat. Could the carbon and GRP ones be different?

I reply to every thread Posted January 24, 2002 Author Share Posted January 24, 2002 I did buy a new seat - it came with the suggestion that adjustable runners would be available at some point in the future. In fact the second hand seat came with the same indication. I'm just impatient. (I was also told that the existing sliding runners could be modified) I'm thinking of bolting the seats to the runners to the floor??? The only difference to the existing setup would be the absence of the two Fore-Aft flat steel sections that were previously bolted to the chassis below & seat runners above(and the presence of bolts attaching seats to runners rather than the ally rivets that were there before!) Well - what d'ya reckon? How high do you think you need the front of the seat base off the floor then? How much spacing has Count got? Link to comment Share on other sites More sharing options...
EFA Posted January 24, 2002 Share Posted January 24, 2002 Matthew, You need to get some 2" wide ally channels made up (same length as runners) and you'll be OK. Front of both seats needs to be raised 3/4 to 1 inch for someone of your inside leg measurement .....oerr.

Jon B Posted January 24, 2002 Share Posted January 24, 2002 Are we talking the composite high back seats ? Do these offer additional leg room over the leather seats, I’m seriously considering changing to the thinner seat to give my 6ft 4inch frame a little bit more leg room in my SLR Have already secured the current leather seat as far back as it will go by removing the base bar at the back of the seat, this has allowed the seat to go back another couple of cm or so without impacting on the strength of the seat Has anyone any idea on how much more room I’ll gain, also how much lower I’ll be even with the seat tilted? Also, where’s the best place to get this high back, thin style of racing seat I think they’re £260 odd through Dartford?

NickB7 Posted January 24, 2002 Share Posted January 24, 2002 by adding spacers to the front you can get very comfortable with these seats and give you a fair bit of space. my car did not have any channels under the floor so i have used large washers but my car does have honeycomb floor and this came with reinforcing tubes for the seat runner bolts to go through Link to comment Share on other sites More sharing options...
I reply to every thread Posted January 24, 2002 Author Share Posted January 24, 2002 Jon B - Carbon Kevlar are the thick end of £500 each with the VAT(& they're "only" wet lay up) There's a german guy that will sell you genuine vac formed carbon for £650+ each (I think - he gave me the price in eurines) Then there's Caterham glass fibre (same pattern) which is much cheaper.

EFA Posted January 24, 2002 Share Posted January 24, 2002 ...and not much heavier.....as the Carbon Kevlar seat has a GRP base.

I reply to every thread Posted January 30, 2002 Author Share Posted January 30, 2002 The leather runners can be made to be compatible with the Tillet seats. Takes quite a while though & doubles the weight of the seat unit as a whole! Link to comment Share on other sites More sharing options...
robmar Posted January 31, 2002 Share Posted January 31, 2002 Aves - I was surprised to read your comment "Caterham are all out of sliding mounting sets for Tillets & will be for a few weeks to come" as I bought a set from caterham last saturday, which was the 26th, and they look identical to the ones on my leather seat! I have had to drill some extra holes in them to fit my seat, but wasn;'t too much effort rob Link to comment Share on other sites More sharing options...
I reply to every thread Posted January 31, 2002 Author Share Posted January 31, 2002 Hmmmmmmmmm - Well mine hasn't arrived yet. Maybe I'll send a reminder to Jason. What is the slider made of? Steel or Ally? Link to comment Share on other sites More sharing options...
robmar Posted January 31, 2002 Share Posted January 31, 2002 steel i would guess , judging by the weight it was also quite tough to drill they do add about 500% extra weight when compared to just the seat rob Link to comment Share on other sites More sharing options...
