  1. What kind of proof would I need. These are machined in Canada, and claim to be "Precision CNC machined from 6061-T6 and 7075-T6 Billet Aluminum" Would I need some kind of formal documentation? Its a small company who should be able to provide whatever is necessary.
  2. Any ideas why this isn't certifiable? https://www.redlineperformance.co.nz/product/hardrace-to-suit-altezza-aristo-rear-upper-adjustable-arm/ Is it because we just dont allow this type of arm, or the rod end, or just because China? I would have thought at least these upper arms would be okay with multi link rears since there would be negligible load? Looking at picking these up https://www.serialnine.com/product-page/is300-jzs161-jzx110-billet-serial999-rear-upper-control-arm but thats waaaaaaay too much money for something that is also unable to be made legal here. No welding to be turned away with these. (Hopefully image isnt too big here) Ideally lower arms like these would be the go instead (cheaper). But i think other people have been turned down with the equivalent hardrace, due to design rather than poor quality? https://www.serialnine.com/product-page/jzs161-is300-jzx110-rear-lower-control-arms
  3. Increasing steering angle. I get quite fuzzy with the terms thrown around in the standards. Specifically toyota lower ball joints as pictured below. You can get cast items, not cut and welded that increase steering angle. (And i'd assume quicken up steering?) Is this something that is legal? Assuming there were no other issues caused, so rubbing of guards, frame rails or contact with control arms, is there any reason these cant be certified. I'm guessing they change ackerman but thats over my head at this point.
  4. That’s kind of what I’m getting at. The Bilstein struts and coilovers would have the same steering arm attached in the same way right? The replacement struts are fine for wof, but should I try to cert the car for something else they fail due to the construction?
  5. Not oldschool but I've never actually seen confirmation on this. DC5 Integra / EP3 Civic front shocks. I know these chassis suffer from serious bumpsteer when lowered, but that shouldn't apply when retaining the stock height. They have a pickup for the tie rods on the shock itself as seen here. (Not a great pic) I've read that this is the issue with aftermarket coilovers. However i'm not sure why, is it to do with materials, angles, both? A few companies still make shocks & full adjustable coilovers for them, and while I can kinda understand why the usual Taiwanese suspects aren't given a pass, surely a company like Bilstein can be trusted to build something to a standard at least as good as the OEM? Their offering seen here. Would something like Bilstein or KW actually fail to meet the requirements, or is it a matter of everyone wanting cheap & cheerful? As a side note, Tein, Bilstein & historically others have made OE replacement shocks for these chassis. Am I correct in assuming that these will pass a legit wof because they are OE level replacements? And that the issue comes in at cert time due to an LVVTA rule? Surely something from any of these reputable brands would be better off than the generic £80 replacements I've found out of the UK which I also believe would be perfectly legal here? I'm looking at picking up a civic and I've noticed that front shocks have been discontinued by Honda so I don't want to find myself in a position where I'm caught out with blown shocks and no real upgrade path.
  6. What the go with cutting down the footplate of an auto brake pedal during a manual conversion? In case the manual pedal I've found doesnt actually work, I'll be looking at cutting down the auto brake pedal on my crown. Cant find any real info about this in the car construction manual. I'd be using another toyota manual rubber pad as a template, however i'd ideally like it offset as far to the gas pedal as possible. Is there a rule of thumb in this situation, eg at least x% of the footpad must remain on each side?
  7. Its a valid question. You can get the details up with just the number on the tag and the vin. If they have cell but not internet I imagine they could call and get someone at their home station to look. Whether or not they'd bother is up in the air. I think I'll save the details page as a pdf on my phone for if this situation arises and hope for the best.
  8. It was for me when getting 215/45R15 Toyos certified on a 15x8 as they're smaller than the required 225width. Showed the certifier the details on the Toyo UK website as the NZ site was useless. He was all good with it.
  9. This seems to be an interesting byproduct of the new tags over plates. Say you went through cert to with quality coilovers that have nobody in NZ willing to rebuild them. 5-10 years down the line of daily driving on our shit chipseal roads and they're due for a rebuild. Unaffordable to send offshore for a rebuild, and say the product line was discontinued. You now can't just get another set of BCs for example, as you'll fail the next wof if they go by the book? I get that it has probably always been the case, but without any more detail on a plate than "Adj Suspn" its never been an issue.
  10. Out of interest for coilover manufacturers. What about Japanese brands that aren't well known here? I've got some KTS coilovers which seems to be somewhat common in Japan, but a tier below the name brands, ie HKS, Apexi, Tein etc. Would a quick google from the certifier be enough to see that its not a shit chinese brand, or will i run into issues as its likely they'd have never had them presented for cert previously?
  11. Did you have to use a 3/4″ master cylinder? I've seen this recommended for the Quartermaster release bearing. I'm looking at using a ORC or OS Giken clutch with their movement kit to turn it from a pull to push clutch. But the hydraulic bearing would make life easier (and cheaper).
  12. I've bought a fresh import Mark II that has been registered as a "Chaser Mark 2". I've planned to go to the compliance centre to get them to submit a LANDATA correction form, however the cert plate also says Chaser. If i get the registration changed to a Mark II, am I just able to contact the certifier to get a new plate with the correct model? Note that the dealership did the cert not me.
  13. Ahh sorry about that. The 100mm measurement was the ID using my aliexpress spec measuring calipers. As for the measurements on the silencers, guess only way know would be to measure by hand.
  14. I've bought a new money pit thats exhaust is to loud for extended driving so I'm looking at throwing a silencer in the tip but I'm a bit unsure on sizing. Its a 100mm tip, and there are 100mm silencers out there, however they dont seem to reduce the volume that much. AdrenalinR do ones that drop the volume further (and NZ made) but the closest size in 98mm. Is this going to be a problem with it rattling or too much airflow escaping around the silencer?
  15. A fellow hairdresser has offered the use of his syncrometer so I'll pick that up whenever i can. Currently running with 16v throttles although I have a set of blacktops in storage. Seems like the adjustment will be much the same. Not looking forward to doing that on the car though. The map sensor i had hooked up as I was going to try run the megasqsuirt "ITB" mode, which uses speed density close to idle, then has a changover point for alpha-n. Based on the quick drive around the block I did before noticing the misfire, its probably not needed as it felt drivable down low as is. And yes I can use the exisitng map sensor for baro correection. I'll cap off the vacuum on the fuel pressure reg. Its not something i thought about but what you say makes sense. Cheers for the advice, hopefully can have it sorted soon enough.
