Book locost chassis and tall driver.
My old man is around 6'3 and Im 5'8 so we need to mount the drivers seat on runners. I have some from a nova which are only an inch
thick.
Ive been looking at triton fibreglass seats.
due to the number of mods away from the book this is a long term project and I dont want to buy seats just now just to have them lying for 18 months,
but I do need to know where the pedals are going so i can mock up the engine mountings etc.
At the moment Im thinking of going either top hinged and with vertical cylinders under the scuttle, or floor hinged and master cyls thru into the
bottom of the engine bay.
if the seat is fitted so its touching the back panel int he cockpit, will there be enough room for dads legs and then the pedals?
Cheers

More than enough. I was suprised at how much room i have behind my seat (im 5'8), there is loads 
How long can i resist the temptation to drop a V8 in?

I'm 6' 2" and the only way I could drive my book locost was with no seat at all.
It really does depend on where your height is.
Seabass has seats in his and he's taller than me, so it really does depend on more than your height.
The sylva I am more comfortable with, but that has an extended pedal box on the driver's side.

I am 6'3" and there is NOT loads of room 
I am using a obp floor mounted pedal box and baby cub seats and just find it ok.
I have bought and sold a few sets of seat and found the fiber glass ones tend to lay back at more of an angle than others thus robbing leg room.
at 6'3" he will need every inch he can get.
I have a bigger problem and thats the size 12 and a bit feet in the bottom of the tunnel.

I'm 6ft4 and had to get Kirkey Prodrag seats which almost exactly follow the angle of the back panel (they are also very shallow) to maximise
the amount of room available. Just about works Then again the majority of my height is in my legs....
I'm not sure runners will be possible but heyho!!

Really best to mock up the whole thing, as some tall people are going to have a problem, and some aren't. I used to be 6'4", and
just thinking about trying to get in a standard locost sets off my claustrophobia

I win....! I'm 6' 6", with size 12s and a 37" inside leg! I find it a tight fit in my ST (with a combo of the Sierra steering
wheel and the seat edges restricting where my legs can sit). I have fibre glass seats (from GTS) and they are on seat runners. It is certainly snug,
but more than drivable. A change to smaller wheel is going to make it much better. I have floor mounted brake/clutch, and top mounted accelerator.
When I tried sitting in cars at Stoneleigh, I found that floor mounted pedals seem to make a real difference to the leg room available.

Hi
The standard Book ( I assume we are talking Ron rather than the later Haynes version ) chassis is more than capable of accommodating drivers over 6Ft.
There's 2-3 well over the 6Ft mark who are racing with no issues regarding fitment.
Although there are different ways of achieving that height. Some have longer legs some have a longer upper body. Some just wear high heels. . But
the point is that what becomes the more difficult part of the problem is getting the steering wheel and pedals in relationship to each other right.
Something that many of the manufacturers dont realy take into consideration. But to be fair they are not building bespoke cars. So that is where to
focus your attention. All the manufacturers use simalar type fitment pedals but it's where the pivots are ( Assuming we are talking floor
mounted ) distance wise from the bulkhead. Best bet is to make the pedal tops adjustable foward and back so that a final location can be made to suit
you both once your at the stage when the seats etc are all fitted.
Can not see any reason why you would want to go top mount etc when floor mount will provide the most compact and rigidly mounted setup. Unless of
course you are thinking of having a whole top mount setup with sliding adjustment as a complete unit.
HTH cheers Matt

according to uncle rons book the top edge of the rear panel is 119mm further back than the rear edge of the floor and this occurs over a height of
533mm giving a 12.6 degree back angle for the seat to maximise legroom.
thes seat runner will bolt to tabs welded tot he chassis tubes and sit on the floor between the chassis rails, so the seat bottom will mount as if to
tops of the chassis rails, or a transverse seat mount bar.
Dads only a 34 inch inside leg and size 11 feet, so better off than some of you guys!
Looking like a floor mount pedalbox is the way to go.....

Are the racers allowed to use floor mounted pedal boxes?
What seats do they tend to use, as most of the grp ones for kitcars arent fia approved....

Hi.
To create more space I sheeted the end of the foot well with a piece of metal that had a large square hole in it.
Cut / folded / welded up a box that I drilled to take the master cylinders and bolted this in the hole.
The pedals I mounted on the bottom cross member so that when depressed they go into the recess of the box.
This effectively lengthens the foot well by about 60mm.
The pics below may explain this better than I can with words.

That looks excellent!
Time will tell if it is required, looks a tad short on room for going with twin brake cylinders and a hydraulic clutch unfortunately!
Guess I just need to get him int he car with some cushions

Yup, that's a Cortina M/C with a fwd Escort cap for the electrics.
Please don't mention cushions. The wife will be fitting pink fluffy ones if she reads this.

Is it too late to just put some extra length in the cockpit section? easy enough to do and doesn't mess up anything else.

I'm 6'3" and if i'm sat on the steel floor i'm too low and too far back. I need to be an couple of inches closer
forward.
Why not get boat foam like the racers, put it onto velcro and make two sets - one for you and one for your dad. Then swap them from the left to the
right as you change seats - just like le mans racers etc. Cheaper / Easier (ish) and guarenteed good fit for you both.

yeah, chassis was bought complete so it would be quite a lot of work to revise now.
Foam seats are a good idea, would be nice if it was universal enough that mates could drive it and stuff,at the expense of the ultimate support
offered by the foam pour seats.
