cletus Posted March 3, 2022 Share Posted March 3, 2022 Technically only a certifier is allowed to remove or fit a cert plate You will end up with 4 holes to fill and paint too 1 Quote Link to comment Share on other sites More sharing options...

GARDRB Posted March 7, 2022 Share Posted March 7, 2022 @cletus how likely are these to fail cert on a scale of “this will show up in the fabrication foibles” thread? I'm picking they won't be looked upon favourably. (Rear shock in a Hyundai H1/Imax with separate coil.) Quote Link to comment Share on other sites More sharing options...
cletus Posted March 7, 2022 Share Posted March 7, 2022 Eeesh Never seen that before apart from in a "hey look at this dodgy shit" thread Looks like the eye would be under a lot of stress welded on the side like that especially if the bump stop is on the shock Would definitely need some input from LVVTA before certifying that 2 1 Quote Link to comment Share on other sites More sharing options...

Might be worth going to a traditional shock of the right length or moving the eye. We'll get them in and see what we're looking at Quote Link to comment Share on other sites More sharing options...
Bling Posted March 8, 2022 Share Posted March 8, 2022 Could add gussets full length of the sleeve? Quote Link to comment Share on other sites More sharing options...
cletus Posted March 8, 2022 Share Posted March 8, 2022 Yeah possibly. It probably looks worse than it actually is just because it's different There's 2 potential issues I can think of , one is as previously mentioned, the eye being stressed but like bling says a gusset would fix that The other thing is the loading on the shock shaft will be slightly off center. Which would be similar /less than the loads in a mcpherson strut type suspension So if the internals of the shock were the same spec as a mcpherson strut (they have a bigger shaft and bushings to handle more load) then its probably ok Quote Link to comment Share on other sites More sharing options...
Bling Posted March 8, 2022 Share Posted March 8, 2022 Ah yeah didn't think about that loading. Banana shock anyone? My rear shocks came with similar length sleeve which doesn't make sense (to me) when you have a shock with that much thread to make use of. I ended up swapping mine for sleeves twice as long. Eye is pressed into bottom of sleeve so different design in that area. Quote Link to comment Share on other sites More sharing options...

Would be a super simple job and the base is steel rather than alloy which is nice. Alternatively, it's actually longer than the factory shock, so the factory shock would fit in there (not valved for the springs, but our certifier up here is a pillock and wouldn't know shock valving and spring rates if they took a steaming giant shit on his chest). My cousin (vans owner) is an engineer and the suspension company has asked for feedback and installed pics so can probably go back and say "this is shit, send us a shorter shock insert and a base with an eye on the bottom rather than the side". 1 Quote Link to comment Share on other sites More sharing options...
cletus Posted March 9, 2022 Share Posted March 9, 2022 It's likely done that way so the manufacturer can get away with using a common length shock, I'd bet that most cheaper adjustable suspension companies have a few different length inserts and make top and bottom mounts to suit each vehicle, whereas more expensive high end setups will be made specifically for the car The fact it has that damper adjuster setup at the top adds a bit of length, if it was a shock designed for that application then it would probably be more expensive but the adjuster would be at the bottom on the body 1 Quote Link to comment Share on other sites More sharing options...

rusty360 Posted March 21, 2022 Share Posted March 21, 2022 Hey Mr Cletus, have you ever certed some seat belts in the back of a 105e anglia saloon? Quote Link to comment Share on other sites More sharing options...

Banga Posted March 27, 2022 Share Posted March 27, 2022 I know there are specific limits in terms of camber when going through a cert but is there anything similar for castor? I’ve gone from a steering box to rack and pinion and it’s increased the castor quite a bit - do I have to stay within factory specs? Quote Link to comment Share on other sites More sharing options...
bmxnz11 Posted March 27, 2022 Share Posted March 27, 2022 Slipping a bit of garden hose on the top and bottom coils of lowering springs to take up the tiniest bit of play when the struts are unloaded. Still fit securely into the bottom and top cups and are captive. Is this a problem come wof or cert time? 1 1 Quote Link to comment Share on other sites More sharing options...

There are suggested figures in the CCM In general= More positive caster = better On a lot of older cars, the factory caster settings are near zero or even negative in some cases. Which doesn't work with modern tyres, suspension and steering 3 Quote Link to comment Share on other sites More sharing options...
datlow Posted March 27, 2022 Share Posted March 27, 2022 @bmxnz11not sure on legalitys but these would be more legit looking https://www.repco.co.nz/en/parts-service/steering-suspension/suspension-bushes/pad-kit-coil-spring-upper-47322/p/A1045688?kwSearch=spring Or Find some skinnier ones of these (mercs have them in different thicknesses fo adjust ride height) https://www.adenstyres.co.nz/products/universal-spring-spacers-10-15mm 2 Quote Link to comment Share on other sites More sharing options...

There's probably nothing wrong with using garden hose and it will likely work fine but it might be the sort of thing that draws attention from someone who might be a bit fussy 3 Quote Link to comment Share on other sites More sharing options...
