Tillett B6 40 extra cut (Caterham Cut) seat

[Wayne Stambaugh]

I’m still fighting to find my ideal driver position in my 86 Caterham S3. I have had several people question the chassis length (cockpit length) and the original build paperwork show “standard chassis” . Based on the fact I’m 6’ tall and the word “standard” in the paperwork, this chassis has to be the shortest one available, otherwise you would need to be less than 5’  6” tall to drive it.

 

I am considering lowering the floor but only as a last resort. Before I do that I think I’d rather try a Tillett seat. I have talked to Tillett and have been advised to order a B6 40 extra cut (Caterham cut) seat, bottom mount. In researching this seat it appears that you can get the bottom of the seat almost making contact with the floor. I haven’t seen the seat in person but the seat shell doesn’t look like it could be any thicker than about 3/8”. Again, this seems to be as low as you can get without lowering the floor. 

 

Has anyone out there purchased this seat for there car? I know Caterham offers a Tillett seat on their website but my guess is that they probably mark it up and I couldn’t get any details about it anyway. Any information or advice anyone can offer will be appreciated.

There are a number of B6 Tillet seats in their range.  I use the B6 Screamer with edges cut in a few Caterhams.  I think I have purchased 6 over the years.  The difference to the regular B6 is one of FIA certification.  The Screamer has been FIA certified - its essentially stronger/thicker/heavier. 

 

I like it - very comfortable.  I use it with the seating pads to stop sliding me moving on the smooth composite surface.

 

I use the seat with the TBI brackets.

Looks like those have a 1.6 inch deep dome bottom.

 

How well do you fit without the seat? Foam squabs can offer more room versus cushion than any removable seat.

Wayne,  I agree with MV8, the first step is to figure out if the problem below, from your build thread, happens if you're sitting in the tub with no seat:

 

" ... I lift my left leg to put my foot on the clutch, my left leg, just above the knee hits the frame tube under the bottom edge of the dash. This restricts me from getting my foot on top of the clutch pedal."

 

If this problem still happens with no seat, them lowering the floor may help.

If you fit well in the bare tub, you might web search for Truckers Seat Cushion.  Open cell or memory foam, with finished edges and no cutting.

Or consider a poured seat as in many formula cars.  Super comfortable but take some skill to do well.  Look at Pegasus. If you don’t fit with no seat in????

I have the B6 Caterham cut seats in my S3. With the tunnel cover in my car, they were still a bit wide and I needed to grind a bit of additional material off of the sides for them to fit. I find them comfortable, but my wife and son not so much. Perhaps I have more built on padding. They will be a little lower in the car if you skip using the adjustable rails and bolt directly to the floor which I would recommend as moving them forward and back isn’t very easy anyway once the rails get any grit and stones in them and the actual range of movement isn’t much.
