(not trying to hide anything its mint) I just re registered a Falcon, inspection cost $400. I had already undersealed the bottom as it had spotty surface rust. 1 Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted November 3, 2019 Share Posted November 3, 2019 If they spot any rust they'll ram their cock so far up your wallets arse, itl be able to floss with their banjo string. Any rust (or evidence of previous rust repairs) will require a repair cert. I've heard horror stories of people having to remove new paint jobs to get repair cert. 1 1 Quote Link to comment Share on other sites More sharing options...
linearentropy Posted November 3, 2019 Share Posted November 3, 2019 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.

I can drag it out for a look/send it to you if you like.. That would be awesome. The chassis that I bought only had the steering as far as the box wasn't aware of that. Got the engine and gearbox in the hole for the first time and realised I can keep the OG column as far as the firewall, so will mean I only need an intermediate shaft to adapt the collapsible Saf part to the Datsun column, which is significantly easier than what I was expecting.

I will see if I can find it this weekend, it will be pretty buried in the container. 1 Quote Link to comment Share on other sites More sharing options...
Shakotom Posted November 7, 2019 Share Posted November 7, 2019 For cert How much clearance is enough clearance between a wheel and inner guard at full lock? understand it’s subjective etc can I beat inner guard with a hammer to gain clearance?

KKtrips Posted November 7, 2019 Share Posted November 7, 2019 It can't touch the body at any point. But probably 5mm is enough clearance. 1 Quote Link to comment Share on other sites More sharing options...
Esky_addict Posted November 11, 2019 Share Posted November 11, 2019 Any regulations regarding suspension travel for a cert like is there a minimum travel requirement before bump stop contact Quote Link to comment Share on other sites More sharing options...
cletus Posted November 11, 2019 Share Posted November 11, 2019 40mm bump 40mm droop from ride height. Depending on the car and suspension and bumpstop type, can include some bumpstop compression in that figure 3 1 Quote Link to comment Share on other sites More sharing options...
Bling Posted November 14, 2019 Share Posted November 14, 2019 So that is 40mm minimum from bumpstop if said bumpstop can not be part of the compression? Have been doing some maths with my springs and in theory i'm in for a fun time come cert time. Not even running silly (IMO) spring rates, shits going to be tight like a tiger. I better put my thinking cap on, good to know what numbers i'm working too though thanks. Quote Link to comment Share on other sites More sharing options...
ajg193 Posted November 14, 2019 Share Posted November 14, 2019 I'd assume 40 mm of wheel travel from bump stop, not 40 mm of gap between bumpstop and suspension as there are big lever ratios and whatnot. Ie the hilux has maybe 15 mm of clearance between arm and bumpstop. Quote Link to comment Share on other sites More sharing options...
Bling Posted November 14, 2019 Share Posted November 14, 2019 Yeah that would be correct. In my case the bumpstops are within the coils, so not much lever ratio going on, unless I am misunderstanding it. Quote Link to comment Share on other sites More sharing options...
KKtrips Posted November 15, 2019 Share Posted November 15, 2019 Running adjustable coil overs? Keeper springs might be your saving grace. Quote Link to comment Share on other sites More sharing options...
Bling Posted November 15, 2019 Share Posted November 15, 2019 Yeah will be running adjustable coil overs. Was speaking to someone running higher spring rates and keeper springs is what they had to go with. Different chassis though so I guess i'll just have to put them in and see. 1 Quote Link to comment Share on other sites More sharing options...
KKtrips Posted November 15, 2019 Share Posted November 15, 2019 Unless you have short and super hard springs then 40mm of compression should be easy otherwise you are going to need lighter springs. Droop should be manageable too, just takes some braining to figure out the best way to adjust your adjustables to get it. 1 Quote Link to comment Share on other sites More sharing options...
Bling Posted November 15, 2019 Share Posted November 15, 2019 Springs are F-6KG/R-4.7KG, fronts are easy with keeper springs if required, rears not so much. Rears i'm going with OEM setup so I don't need to worry about shifting the car weight to the factory shock location. What that does mean however is that the rear springs are factory(ish) diameter, so doubt keeper springs will exist. I think the spring rates should be suitable for a road car. At a kerb weight of around 950kg, my downfall is the lack of weight in the rear of the car to create the droop. Will of course discuss all of this with my certifier when he inspects my parts soon, but always good to do homework now and come up with solutions. In theory I need 190kg in each rear corner to net 40mm droop. I the front I need 240kg in each corner. Tallied up I get 860kg, I imagine any extra weight I can actually use will be in the front, with the diff and wheels bringing in the rest of the total. Brain is melting at this point. Maybe a towbar made from girders is the solution. Quote Link to comment Share on other sites More sharing options...

A typical coilover with a foam type bump stop can compress quite a lot so you could include 10-20mm of bump stop compression IMO Depends on suspension though and the application so by no means is that set in stone and a different certifier might have a different opinion Also IMO, keeper springs to fix droop issues is a bit of a band aid 'box tick' fix as the whole idea of a minimum amount of droop was to make sure the spring rate was ok for a road car 1 1 Quote Link to comment Share on other sites More sharing options...

It stops cars from picking up inside wheels around corners and keeps wheels on the ground over big dips and bumps. @Bling - are the springs you’re using on an adjustable perch, or are they at a set height? If you can’t fit keepers and don’t get enough droop then adding weight at cert time is the only option (full tank of gas, couple of duffel bags full of concrete etc). 2 Quote Link to comment Share on other sites More sharing options...
mjrstar Posted November 15, 2019 Share Posted November 15, 2019 I don't have a lot if time for a flimsy 5 or 10 lb keeper, but a heavyweight second spring (80lb plus) can be quite an improvement.. I was able to give my honda an extra 30mm droop, as its light in the rear spring selection was a bit tricky.. Even with perch and lower body adjustment.. / goes good now. 5 Quote Link to comment Share on other sites More sharing options...

Their website says they are progressive to soak up bumps etc, which might mean that you'll get extra droop when compared to a linear 4.7kg/mm spring. https://shop.battlegarage-rs.com/products/bgrs-x-swift-ae86-springs-rear-coilover-type 1 Quote Link to comment Share on other sites More sharing options...
