cletus Posted August 6, 2012 Share Posted August 6, 2012 all up to wof issuers discretion apart from bumpstops, if they are modified it needs a cert. however lots of cars still get wofs with mod b/stops because the wof issuer doesnt notice/care they have been modified. as far as travel goes i think the wording in the wof book is "must have adequate travel from unmodified bumpstops when laden" Quote Link to comment Share on other sites More sharing options...

M Night Shamalayan Posted August 7, 2012 Share Posted August 7, 2012 How legit is it for me to slot the mounting hole on the rear upper arm in my mx5 to dial out some of the negative camber? I noticed it was mentioned earlier about slotted mounting holes to dial out camber, but I was unsure whether this suggestion was srs.

kyteler Posted August 12, 2012 Share Posted August 12, 2012 Clint, my fine friend. I have been led to believe in the past that instances such as this are a definite no no... Could you clarify for me what the deal is with people cutting such holes? Quote Link to comment Share on other sites More sharing options...

Testament Posted August 12, 2012 Share Posted August 12, 2012 Regarding WOF's, is there a minimum suspension travel rule? Or a minimum gap between arm and bump stop measurment? Also, are you able to modify bump stops? Or is it all at the discretion of the WOF man?Cheers! ah you have been looking at/working on the lada. you are definitely going to have to cut those to get where you want to go. 124 sits about 10-15mm from the bumpstops as it is. the factory bumpstops are huge though (presuming the lada ones are similar), so there is quite a bit of scope.

Vintage Grumble Posted August 12, 2012 Share Posted August 12, 2012 ^ Indeed I have, the front end of these things do not lend themselves to lowering do they. Hence my next question for Mr cletus. I need to remove some steel from my front top suspension arms, and then weld in a new strip to box them up, like this: (^ except I would do them waaaaaaaay better/prettier/stronger) Am I able to get a cert after doing such things? What process would I have to go through? Have a ticketed welder weld them and then have them crack tested and so on?? Thank you very muchly kind sir. Regards, VG.

I noticed it was mentioned earlier about slotted mounting holes to dial out camber, but I was unsure whether this suggestion was srs. if you do it properly, i cant see why it couldnt be certified- have seen racecars with lower arm mounts slotted, then a heavy washer welded to the x-member when alignment correct so it cant move Quote Link to comment Share on other sites More sharing options...
cletus Posted August 12, 2012 Share Posted August 12, 2012 Could you clarify for me what the deal is with people cutting such holes? usually ok if its for a reason ie an intercooler pipe, if its not bigger than it needs to be, if it goes thru a part that doesnt contribute a lot of strength, (ie that part of the inner guard, theres often holes for washer bottles, factory ic pipes on nissans, etc) also it has to be done in a 'tradesmanlike manner', it amazes me how many of these i see that look like they were done with an angry dog or a hammer and chisel Quote Link to comment Share on other sites More sharing options...

Regards, VG. you are most certainly able to do that, hobby car manual states any modifications to a production front suspension must be tig welded and crack tested. how much are you chopping out?

Had a cunt of a WOF inspector years ago saying mine were cut too close to the chassis and tried to make me have the section of inner guard along with that section of chassis cut out for a panel beater to inspect then weld back in Quote Link to comment Share on other sites More sharing options...

Its only about 15mm of flat steel I think, and its not boxed to start with, so the arm should be waaaay stronger after its done. So I would need like a crack testing report to take to the cert man ayy? Whats a cert go for these days? Cheers heaps sir! Quote Link to comment Share on other sites More sharing options...

cletus Posted August 12, 2012 Share Posted August 12, 2012 Whats a cert go for these days?Cheers heaps sir! depends on the certifier and thier location/travel time- stuff like that but up here in high-roller auckland, we charge 460 incl gst retail as a basic cert, depending on the mods it goes up from that Quote Link to comment Share on other sites More sharing options...
Vintage Grumble Posted August 12, 2012 Share Posted August 12, 2012 I was just talking to a local engineer about the crack testing, does it have to be x rayed or is a std spray on crack test ok? Quote Link to comment Share on other sites More sharing options...
vivaspeed Posted August 13, 2012 Share Posted August 13, 2012 CBF trawling through lots of search results, so... I have bought another Viva 2 door which I received on the weekend and the front seats have a pivot arrangement at the front and just lift up to gain access to the rear (like a Mini IIRC). There is no clamp/restraint on the back so they just sit there on some plates. The seat has a release lever on the side and a clasp thing underneath, but there is nowhere for it to clasp onto (some had a small bar under the seat). No holes in the carpet, no holes in the floorpan, nothing that gives any hint it should hold on or that there was ever a bar there. Seems odd, seats are original (or original type with front pivot). WOF book suggest provided the original mountings are no broken it should be okay for WOF, but seems a bit too dodgy for me (car has had WOF in this state before). Opinions/Experiences?? I can install a small bar using 8-10mm rod under the seat so it has something to clasp onto and be 1,000x more robust, but then that would consitute a modification? Would anyone even notice?

SP450andLE Posted August 17, 2012 Share Posted August 17, 2012 If I was to cave in to my cravings and get an adjustable suspension kit for the Mini (http://www.minisport.com/mini-spare-par ... SKIT5.html), it would need a cert, yes? Or is it only certain types of adjusties need a cert? Quote Link to comment Share on other sites More sharing options...
