Dudley 206 Posted June 15, 2020 Report Share Posted June 15, 2020 So I have a ke20 with a leaf spring rear. It has 50mm blocks and I’m going to reset the leafs so it will have 70mm drop over all. I will only have about 25mm travel between the diff and the bumpstop in the driveshaft tunnel. Will this fail cert? Quote Link to post Share on other sites
Beaver 8,666 Posted June 16, 2020 Report Share Posted June 16, 2020 Possibly not helpful, but I went through cert with reset leaves and blocks and general requirements (not saying this is explicit or holds true with all inspectors, but its what he told me he needed to see) was not on bumps with passengers in car, reasonable car to road clearance when on bumps (from memory he said 50mm), and not flat/cut down bumps (i.e. they needed to have some give). i was about 100 mm drop all up though. In the end I went from 2" to 1" blocks and some less cut down bump stops.. 1 Quote Link to post Share on other sites
Bling 21,084 Posted June 16, 2020 Report Share Posted June 16, 2020 To quote Clint Quote 40mm bump 40mm droop from ride height. Depending on the car and suspension and bumpstop type, can include some bumpstop compression in that figure So that is probably a good place to start. For context, start reading here: https://oldschool.co.nz/index.php?/topic/17433-for-questions-regarding-wofscertsnumber-plates/page/327/ While there are some rules with little leeway, your best bet is to touch base with the certifier too. Saves going down the wrong track. 1 Quote Link to post Share on other sites
MACKAZ 3,073 Posted July 3, 2020 Report Share Posted July 3, 2020 @cletus @KKtrips I heard/read/dreamt that engine mounts attached to chassis require a plate welded to chassis (larger that actual mount) then mount welded to that. Did I actually dream that? If so how thick does the plate need to be, and recommendation of wall thickness for the actual mount? With the Ford's mounts being further back than the Holden the mounts will be where the chassis bends, so will need to be made of formed plate. Or can I use a large round mount like so and have a flat plate mount Quote Link to post Share on other sites
cletus 39,266 Posted July 3, 2020 Report Share Posted July 3, 2020 A mount attached to the side of a chassis rail has to span the whole height of the rail So if your chassis is RHS you cant butt weld a flat plate to half way down the rail as it will cause cracks. So you could either make gussets that go full height of the rail, or weld a reinforcing plate on first which I'm picking is what you are talking about Quote Link to post Share on other sites
MACKAZ 3,073 Posted July 4, 2020 Report Share Posted July 4, 2020 @cletusThanks mate. I'm picking I will go with a 3mm reinforcing plate (if thick enough) then use a mount similar to pictured above. Sound above board? Reason I'm asking here is our certifier up here is super unhelpful. Just a dick to deal with.....

jono007 344 Posted July 4, 2020 Report Share Posted July 4, 2020 Has anyone here had any issues having Hardrace suspension bits certified? I have had them on the car for a while with no issues just want to get it all legal beagle. Quote Link to post Share on other sites

jono007 344 Posted July 4, 2020 Report Share Posted July 4, 2020 Yeah the rear lower arms are a spherical end and the front camber arms are just a hardened rubber. Quote Link to post Share on other sites

Popular Post cletus 39,266 Posted July 5, 2020 Popular Post Report Share Posted July 5, 2020 Rear lowers will be an issue if they have an adjuster on the inner bush end but it depends how far outboard the shock mount is, LVVTA does not allow any side loading on a threaded joint, sometimes if it is within the load rating of the joint we can pass it if we can do calculations to prove it's ok Fronts if its upper arms, have not done any hardrace altezza ones but the usual issue on that design of suspension is when the car is low enough to need camber arms = the upper ball joint hits the body before the bump stop limits the travel= the car has to be raised= then it doesnt need camber arms any more Also the adjustable arms are usually taller or longer or a different shape in the ball joint mount area so they make the problem worse than with the standard arms In general, hardrace stuff is ok, you do have to make sure the welding is good though as some is shit. The reseller here swears they are all welded by robot but I've seen a few where the robot forgot to turn the gas on, the robot missed the join, or the robot fucked up the weld, ground it down and had another go.

ul9601 802 Posted July 6, 2020 Report Share Posted July 6, 2020 A silly question - is there a reason why rego sticker is bottom left of the screen and wof top right? Or is it just random? The reason I ask is I want to put overlay on the top of the screen but if I do that the wof sticker will have to come further down from the top right corner. I'd rather have wof sticker out of line of sight, along the bottom corner of the screen etc. 1 Quote Link to post Share on other sites
tortron 64,375 Posted July 6, 2020 Report Share Posted July 6, 2020 I believe there's words to the effect of they must be mounted as close as practical to those corners. Splitscreen Morrie has always had wof at bottom right, they keep sticking it back on there without asking. Top right would be directly in your vision 2 Quote Link to post Share on other sites
AllTorque 41,757 Posted July 6, 2020 Report Share Posted July 6, 2020 WOF needs to be on the drivers side. It does not have to be at the top. Affixing the WoF label The WoF label must be affixed by the vehicle inspector or a delegated employee of the inspecting organisation in one of the following positions: a) if the vehicle is fitted with a windscreen: i. to the inside of the windscreen facing outwards on the same side as the steering wheel, and ii. as close as possible to the edge of the windscreen where it is clearly visible from the outside and is not obscured by an anti-glare band or sticker https://vehicleinspection.nzta.govt.nz/virms/in-service-wof-and-cof/introduction/inspection-and-certification-process/issuing-the-wof-or-cof-label-evidence-of-vehicle-inspection 3 Quote Link to post Share on other sites
M.H. 6,257 Posted July 7, 2020 Report Share Posted July 7, 2020 You would think with technology these days the stickers would be redundant. With bike wofs is it a requirement to have 2 rear view mirrors or do you just need a right side one? Quote Link to post Share on other sites
Bling 21,084 Posted July 7, 2020 Report Share Posted July 7, 2020 Google: virm motorbike mirrors Then go to the virm link which points to motorcycles, then on that link hit the legislation tab. You'd think with technology these days it would be easier to just do a quick google for such basic questions. 2 1 4 Quote Link to post Share on other sites
