Going for a cert soon...

authentic · Post by **authentic** » Thu Jun 13, 2013 12:29 pm

So I'm planning to go in for a cert for the new wheels and coilovers. The wheels are 15x8 with 195/45 tires streched on which are legal according to the manufacture's spec sheet, and the car currently sits at roughly 100mm (give or take maybe 10mm) from its lowest structural point.

What sort of documentation do I have to provide when I take it to the certifier? I've been told that I will need to take the alignment sheet in, which makes sense for the camber etc. Will I need to provide proof that the tires are allowed on this wheel width also? And is there anything else that I will need to take?

And regarding camber, has anyone had any luck with or heard of certifiers allowing camber specs that are (slightly) outside 'the book'? If I could provide proof from a reputable source that whatever camber value is fine to run or possibly even recommended to run on our cars, would that sway the certifiers decision or would I still be fighting an uphill battle?

Hey man, when you go for it get an alignment done the day before hand and bring the piece of paper

I was slightly out, explain the modifications, explain that you can't actually bring it down anymore.

You SHOULD be okay.

Good luck

I'm just hoping that the guy is reasonable and will allow me to explain things. I don't want to deal with someone who is stubborn or tries to push his weight because he's the 'older' and 'wiser' one.

Dress nicely (I know weird) Show respect and you should be sweet.

If your chassis rails are 100mm from the ground you shouldn't have any problem getting the alignment to factory tolerance anyway

last car i got certed the chassis rails were like 30-40mm from the ground the front was ok but the rear needed some offset bushes to take some of the camber out

Even Im at 90mm! Also you should post pics of your car(From the outside in cert spec)

if i can get this certed then you shouldnt have any trouble at your height

authentic · Post by **authentic** » Thu Jun 13, 2013 7:35 pm

Ok so I just measured again and its more like 60-70mm at the frame rails

. The 100mm was my assumption that the pinch weld and the frame rails were about the same height. They are not.

The subcard is for scale against the smooth floor as you can't tell shit from the pictures without it.

^^this^^

Dressing to a tidy & professional standard and speaking politely and in an articulate manner always helps.

It gives the impression that one knows what one is talking about and that work has been done to a high standard and not done by a munter.

I was about that height and couldn't get less than about 3.5 degrees of camber on the rear.

You will probably either need to raise it or get offset bushes

Hey mate, this wing, where did you find it? My race car is in need of a wing and that style will go well with the matt black.

authentic · Post by **authentic** » Thu Jun 13, 2013 9:26 pm

Where is the best/cheapest place to get some offset bushings if I need them?

sprsta · Post by **sprsta** » Thu Jun 13, 2013 10:39 pm

isc racing for the Bushes You will only need the rear ones
Spoiler is r speed, I didn't find it, its not my car, I just attached it

Heads up for anyone who cares. You can certify a splitter and diffuser provided the splitter has at least a 5mm rounded facing edge and doesn't extend forward of the vehicle. Diffuser can extend rearward, no wider than wheels and any forward facing parts must have rounded edges. Stoked.

Me too

Got a WoF due in about 2 months so I don't have much time. I've only got adjustable struts, at a sensible ride height. Seems a massive waste of money for such a minor mod. I'd like to do a rollbar, and seat(s) in future, but I'm not sure if that would require another LVV cert.

Snapfrozen · Post by **Snapfrozen** » Fri Jun 14, 2013 4:19 pm

Depending on rollbar design it shouldn't. As you aren't invading the "foward passenger compartment" of the vehicle. Seats shouldn't if you use factory rails or a well reputed brand.

marcellarius · Post by **marcellarius** » Fri Jun 14, 2013 4:27 pm

But the rollbar needs to be behind a plane going upwards from the back of the seat backrest, which seemed like it may not be the case for an effective rollbar with the standard seats.

EDIT: to add a question, do roll-bar people on here have any issue with the standard seats going under the main hoop?

Snapfrozen · Post by **Snapfrozen** » Fri Jun 14, 2013 5:27 pm

Get new seats

You'll need to know the height of them for your harness bar anyway (unless its for baller points?)

marcellarius · Post by **marcellarius** » Fri Jun 14, 2013 6:12 pm

I would definitely want to get a driver's seat, I was thinking more about the passenger seat, which I'd avoid doing if possible because $$ etc.

Not going for baller points in the slightest. Just want something safe (-er) that will work for trackdays and hopefully clubsport events.

The stupid thing about the camber changes to certification guidelines is that it has certifiers feeling like they're being held by the balls, but in fact it allows certifiers to exercise their discretion when cars do not meet the stated guidelines.

chris · Post by **chris** » Mon Jun 17, 2013 2:49 pm

Correct ^ However, the certifiers don't want that liability on their shoulders (understandably)

Give it a year or so and I think that they will soften up a bit

I need someone to build me a driveshaft hoop.......anyone out there that can help?

To some extent, yes. But considering that they certainly used to take that liability on their shoulders and certify obviously retardedly cambered wheel settings, it's stupid that suddenly they won't at all, even if they're just outside the guidelines and are obviously safe and/or for a specific purpose.

I'd be hopeful that they soften up with time, but I don't plan on sacking any car of mine again so probably not relevant to me

Going for a cert soon...
