Tubular seat rail installation

I don't think it's CC, since they're 25mm dia in the Demon Tweeks catalogue. IIRC, CC tend to be thicker.

I bought 1 metre of 38mm OD CDS from Merlin Motorsport in the summer for 17.85 incl VAT. It's more than likely you'd need 2 metres though (I got two half metre offcuts), so you can double that - 34.89, and that still excludes the tags and the effort to make them. Makes 40 ready to weld in, with end plates seem cheap tbh.

Quite a nice product though - saves a fair bit of time buying them like that with the tags on already.

 

still rather make my own at that money

 

it's a time v money thing on those premade ones. a lot less hassle to buy some ready mades if your paying someone to do it. you could have them profiled and welded in the car within an hour.

 

mine are all in now had the seats in and bolted down today which was cool the floor is gonna be painted next week so the red oxide will go .

 

are there welded plates on the sills and tunnel that that box section connects to?

 

there is on the drivers sill as it was in need of it but not on the tunnel

 

I used spreader plates on both sides. Much stronger in my opinion.

 

we talked about doing that but decided that there was no point

 

I did go a bit over kill but decided better safe than sorry!

I also used box section 2"x1".

Where did you mount your crotch strap eye bolts?

 

im only using 4 points so no crotch strap . my lap belts are mounted on the std seatbelt mounts on the outside and on the inner i have 2 holes just fwd of the aft bar that has a nutplate behind . not fitted in the pics as the floor needs painting

 

How hard was it to get the right seating position for you legs?

Do you have a row of holes on the seat mounts for forward / backward adjustment when fitting or is it a matter of measure twice drill once?

 

Sorry I meant lap belts. I couldn't see them from the pics so thought you hadn't made them yet.

What I was going to say was if you're mounting a plate and captive nut (FIA spec ones are about 1.50) then becareful when you're drilling the tunnel. You probably know anyway but its doubled skinned, so try not to drill through the second skin. Will help prevent rust between the skins developing.

 

bit of both mike i figured out where i wanted the seat and then put the rails 262 mm centre to centre apart . as the side mounts have 5 positions (262mm centre to centre) so i can move mine fwd and aft

i am however going to buy a dished steering wheel sometime so i can have relaxed arms if you get me ?

 

holes were put in by the previous owner but no rott coming threw there .....................yet !!!!!!!!!!

 

Is it true that in a good seating position if you hold your arms out straight pointing your fingers your wrists will rest on the top centre of the steering wheel?

 

that is the way i did mine . but tbh its all depending if you feel cumfy i guess ! im goona fit a dished steering wheel to relax my arms a bit also .

are you going to the gmvw rr day at tsr mike ? im aiming to have the car there . it won't be banging out massive power as the engine is std (for now : )

 

what day is that? could meet up & have a look at your work.
should see some big things happening in the next few weeks/months with mine also.



edit: to post below....added it to my calender mate

 

5th of april mike . it should be teady by then

 

finished item looks loads better now i can get on with fitting things back in
