johnd-mkiv Posted March 21, 2016 Share Posted March 21, 2016 (edited) Been looking at harnesses for my supra but having the problem of mounting them in the rear, a standard harness bar is no good for me as my seat is touching the rears and reclined a fair amount. Been messing about with designs in between work and finally finished this one which I'm happy with. The brace Picks up off original seat belt mounts with two sweeping bends that sit the bar further back and two adjusterble rose jointed tie rod ends mount to a fixed bracket on the rear middle seat belt point for added brace. If enough interest and ok with mods I'll consider making more as a group buy. Edited March 21, 2016 by johnd-mkiv (see edit history) Quote Link to comment Share on other sites More sharing options...
ripped_fear Posted March 21, 2016 Share Posted March 21, 2016 That looks like you have made a lovely job of it. Quote Link to comment Share on other sites More sharing options...
ashloys Posted March 21, 2016 Share Posted March 21, 2016 That looks fantastic, I'd definitely be interested depending on price and if I've got bucket seats by the time they're available! Have a pair of Takata harnesses here from my 180SX.. lol Quote Link to comment Share on other sites More sharing options...
Parm_93 Posted March 21, 2016 Share Posted March 21, 2016 Any chance you can get one made like the Sparco ones? I'm after one but they are discontinued . Quote Link to comment Share on other sites More sharing options...
johnd-mkiv Posted March 21, 2016 Author Share Posted March 21, 2016 (edited) I wanted to do the tie bars like the sparco ones but my seats won't allow this if you can see by the picture, but I can make two jigs as its the same amount of work Edited March 21, 2016 by johnd-mkiv (see edit history) Quote Link to comment Share on other sites More sharing options...
Parm_93 Posted March 21, 2016 Share Posted March 21, 2016 So you could make a direct replica of the Sparco? What kind of price we looking at for these? Quote Link to comment Share on other sites More sharing options...
johnd-mkiv Posted March 22, 2016 Author Share Posted March 22, 2016 Yes no problem these will be £250 plus postage Quote Link to comment Share on other sites More sharing options...

TheTurtleshead Posted March 22, 2016 Share Posted March 22, 2016 The fabrication looks of excellent quality, as has all your other work you have previously posted. However, and I'm not trying to piss on your parade, but I'm unsure aluminium is the right material for such a safety critical component? That would certainly not be allowed in a race car where harnesses are mandatory. Think of the force that the mass of two big blokes would exert on that in the event of a sudden stop. As said I'm not here just to piss on your parade, but if you sell this to someone and it doesn't do it's job, someone could get badly hurt. Maybe an idea to get one tested?

(Sorry if you already have, in that case please dis-regard this post) Understand your concern, this is a thick wall ally tube that I'm using, having read up on safety regulations for competitive use all ally roll cages are prohibited. I'm a coded welder to a 6g standard I can make these bars from mild steel and stainless but will look into having some testing done, just emailed a couple of companies that are involved with this and a local firm we use to certify all our lifting gear.

wattwatt Posted March 22, 2016 Share Posted March 22, 2016 I'd certainly be interested in one of these John, the sparco setup using the lower seatbelt points would be ideal as I'm fitting a full rear seat delete sub box. Quote Link to comment Share on other sites More sharing options...
skippyboyo1 Posted March 22, 2016 Share Posted March 22, 2016 ive had johns products before, great quality. i also know he can supply steel products if the ally is in question so no problem im sure. Quote Link to comment Share on other sites More sharing options...

johnd-mkiv Posted March 23, 2016 Author Share Posted March 23, 2016 I can get these powder coated in basic colours £40 a set the only red he does is Ral 3020 Not had any response from safety people yet, the only test certification you will have with these are with the welding, due to the concerns of using ally mild steel or stainless will be advised but I'm confident in my design to keep in my car. Of a mod will allow a group buy on these I'm happy to sort out a batch deal Regards John Quote Link to comment Share on other sites More sharing options...
ManwithSupra Posted March 23, 2016 Share Posted March 23, 2016 (edited) What are these made out of? Metal wise... Sorry just seen.. Alloy.. Way to soft even despite it being thick wall. You need to use rollcage spec CDS or T45 for anything like this. Maybe also reinforce the top anchor points, there would be a lot of stress going through those in the event of an accident. Small gussets would help massively. I personally would never install a harness bar in a car without it being part of a roll cage. To protect yourself I would say that you should state for off road use only & have some sort of disclaimer in the event of an accident as they dont have the best saftey record. I am also not trying to pee on your parade, however standalone harness bars are simply not that safe. I am just saying make sure you protect yourself if you produce a product like this.
