Beaver Posted September 25, 2014 Share Posted September 25, 2014 A dude over on nzdatsun got some DIY coilovers built by Howat in welly and they did the circlip steez n factory struts and said it would be sweet and his cert guy agreed as well. Although not sure in the benefit over welding the sleeves on. Quote Link to comment Share on other sites More sharing options...
cletus Posted September 25, 2014 Share Posted September 25, 2014 I was just browsing our steel store, and found some 8" pipe that has a 7mm wall. Was thinking of cutting 50mm wide bands, and then splitting them in half ad the desired height, and welding the flat to them. Be the easiest and tidiest way of doing it i think. i keep meaning to do exactly that and sell for MAX PROFITZ 2 Quote Link to comment Share on other sites More sharing options...

flyingbrick Posted September 26, 2014 Share Posted September 26, 2014 The whole cutting pipe thing is exactly how I did mine Unfortunately I have to pay for materials at work (Lol) and the four I made are already spoken for. But if you don't mind paying a small fee I can cut anyone else a hoop or two. The pipe I'm using is 4" ID and 1/4" wall. Pm me Quote Link to comment Share on other sites More sharing options...
Vintage Grumble Posted September 27, 2014 Share Posted September 27, 2014 I think I know the answer to this, but just to be sure, the size/width wheel that your vehicle is certified with, are you able to swap back to standard wheels after the cert, and everything is chur, or are you forever stuck with that size/width wheel to be legal?

Beaver Posted September 27, 2014 Share Posted September 27, 2014 AFAIK What ever cert plate says is what you must have. Quote Link to comment Share on other sites More sharing options...
Yowzer Posted September 27, 2014 Share Posted September 27, 2014 Yup, although I think you can have more than one set of wheels cert'd to the car / listed on the tag Quote Link to comment Share on other sites More sharing options...
J2Racing Posted September 27, 2014 Share Posted September 27, 2014 I have a project in planning that will require a lot of chassi mods. Basicly I'm wanting to turn a RWD into a Project a 4WD. The donor vehicle is also independent rear not solid . So the changers basicly are converting to independent rear and running drive shafts in the front. (If only it was that easy) My question is regarding doing chassi mods. I see on the LSTA web site this sort of work needs to be approved before starting. What is involved in getting sign off to start doing the work. I have photos of cars done the same overseas these I intend to use as a basic guide but what else is needed?

chees- Posted September 28, 2014 Share Posted September 28, 2014 What ever cert plate says is what you must have. i believe if you cert with stock wheels its labeled oe wheels, and you're allowed to go +/- 20% in width an +/- 1" in diameter. I've got the numbers skewed but i'm pretty sure thats right. Quote Link to comment Share on other sites More sharing options...
cletus Posted September 28, 2014 Share Posted September 28, 2014 like beaver said, once its certed, then you are stuck with what the plate says. so if it says oe wheels, thats what it has to have 1 Quote Link to comment Share on other sites More sharing options...
R100 Posted September 28, 2014 Share Posted September 28, 2014 Does the crack testing thing cover custom made rear suspension arms ? Like if you change your leefs to a 4 link ? Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted September 28, 2014 Share Posted September 28, 2014 You're probably looking at TAC design approval for shit like that. But I'd expect that crack testing would also be required too. Quote Link to comment Share on other sites More sharing options...
Beaver Posted September 28, 2014 Share Posted September 28, 2014 Hey Clint, whats the go with droop? Is there are rule of thumb for how much you need? Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted September 29, 2014 Share Posted September 29, 2014 Iv had a browse through the legislation and I can't see any concrete measurements just lots about how much load they should take. I'm mounting seats that do not use standard fixing points. The previous owner has got the bolts going g through ugly bits of flatbar under the floor. I'd like to replace these with a square plate for each bolt and tack them (and the nut) under the floor. Is there a size I should make these plates so that they go through cert without questions. Minimum thickness? Quote Link to comment Share on other sites More sharing options...
peteretep Posted September 29, 2014 Share Posted September 29, 2014 what were the rules for making your own pedal box again? 8mm plate for pedals, I will have to send the whole unit down to wellington to get checked out? I have it drawn up and it is ready to be made now Quote Link to comment Share on other sites More sharing options...
Nominal Posted September 29, 2014 Share Posted September 29, 2014 what were the rules for making your own pedal box again? 8mm plate for pedals, I will have to send the whole unit down to wellington to get checked out? I have it drawn up and it is ready to be made now " Material having a thickness of equal or greater strength than 8mm (5/16") mild steel" Also says that 5mm is acceptable for unusually short pedals like Lotus 7.
