andaba Posted March 28, 2012 Share Posted March 28, 2012 Alright guys, I've got a bucket seat to put in my Bimmer, but i'm lanky and it's a bottom mount seat so i've got to get some custom brackets made up. Does anyone know any fabricators that would be able to knock them up for me?I have all the designs sorted, and they are only simple, but are a bit much for my tools/skills to handle. They are essentially 2 rectangles (15cmx55cm) of flat, fairly thick steel (5mm+) sheet with 6 holes in each. If anyone can help/knows anyone that can help me out, it'd be much appreciated. Cheers all. Link to comment Share on other sites More sharing options...

shawdreamer Posted March 28, 2012 Share Posted March 28, 2012 wouldn't box section frames be more advisable for your needs? flat plate even at that thickness is inherently weak under stresses seen in sudden impacts. Link to comment Share on other sites More sharing options...
andaba Posted March 28, 2012 Author Share Posted March 28, 2012 I'll improve my drawings a bit and upload them tomorrow. I was going for flat (pretty thick) plate as it requires no welding and keeps my head away from the ceiling! Link to comment Share on other sites More sharing options...

I was going for flat (pretty thick) plate as it requires no welding and keeps my head away from the ceiling! aye I can understand why you'd wanna minimize space taken up as Ive previously fitted Special Edition Rover Vitesse Recaros into a Mk5b and that was a thoroughbred squeeze (had to sacrifice the the pneumatic seat lifter and tilt to make em fit in the end) but Id at least look at "L" plate steel as a minimum alternative over flat as the flat can potentially just curl up like a limp piece of bacon fat in a smack and you'll be seeing the steering wheel coming ever closer very suddenly. "L" plate at least has more strength than flat if your dont wanna use box section....... you do realise that you wont need to use hefty box section to achieve a silly strong sub-frame dont ya?, 15mm cross-section stuff with a couple of bracing plates on diagonals across the frame will give you something silly strong to work with and doesnt raise the height to much if you work it round what ya need.

SteveB Posted March 29, 2012 Share Posted March 29, 2012 My son is building a bmw race car at the moment and had the same problem - 6ft 2. We couldn't use the existing mount as it makes the seat far too high, so that had to come out and he used an msa approved mounting kit which is basically 2 thick wall steel tubes which you weld low down across the footwell and 4 mount plates fitted to the tubes. You may need to consider doing the same. Link to comment Share on other sites More sharing options...

Danzetec Posted March 29, 2012 Share Posted March 29, 2012 I've got 150mm x 6mm flat bar in stock Or we can cut and bend 4mm sheet into angle, channel or Z if you want? You're also fairly local to you if you wanted any welding done? Link to comment Share on other sites More sharing options...
andaba Posted March 29, 2012 Author Share Posted March 29, 2012 (edited) OK, so basically here's a HD run through what i've got: I like the Cobra bracket I have for 2 reasons - they raise me just enough to not be uncomfortable, and also all the holes in them are already threaded. So good security there. Combined with the seat already having threaded holes in the bottom, I fortunately don't need any captive nuts etc. Here's a pic of what the Cobra bases look like - they go horizontally, much like SteveBs race car pics.http://i41.tinypic.com/xqgc9g.jpg I've got to sit fairly far back and low down due to my height/length, so I end up nowhere near the bolt holes. Here's my high tech paint.net drawing of what I need - hopefully this clears up the dimensions a bit more.

andaba Posted March 29, 2012 Author Share Posted March 29, 2012 Forgot to add - the blue bits are the brackets!! The light grey is the seat and the dark grey is the Cobra brackets. Link to comment Share on other sites More sharing options...
Danzetec Posted March 29, 2012 Share Posted March 29, 2012 Can the cobra brackets be turned around to reduce the offset? Looks like the length and width could be reduced too, have you got the final two dimensions (seat left/right)? Link to comment Share on other sites More sharing options...
andaba Posted March 29, 2012 Author Share Posted March 29, 2012 Unfortunately they can't be turned around - the E36 has a stupid shape floor. I wrote the 2 missing figures down at my lockup, but I can't remember what they are. I'll get them ASAP. Link to comment Share on other sites More sharing options...
