Friendly Engineers - Need Permits

[Blinky101]

Heya everyone

I recently copped a yellow for my ride height. Subsequently there is an old guy who works at Welshpool pits who made the list stupidly long.

Now I need and engineer who is happy to look the other way on a couple of safe but not quite legal mods.

PM me if you have heard of any.

Doesn't quite work that way unfortunately mate... Even if you can find an engineer willing to put his job on the line to sign you off on some non-compliant modifications; permits still aren't a 'get away with anything you like' card. If you take it back to the pits with the permits and the inspector still calls you out on those mods then the permits count for nothing and were a waste of money.

Does depend on the modifications of course. Also I realize I'm not answering your question, so please don't take offense. It's just amazing the number of people you see on here who think getting permits for illegal mods will be the end of all their problems.

I must have got the same guy at Welshpool.

My car is too low. ie the exhaust sits below the 100mm height limit. Even the standard front pipe.

Does anyone know if I get coilovers:

1. will I be able to raise it to a legal height? , and

2. will I need/be able to get a permit for them?

If the coilovers are adjustable you should be able to raise it over the 100mm ground clearance. I have Tein adjustables and when I had to go over the pits after bringing my car to the country I failed cause the exhaust was sitting at 65mm, I drove to the back of the line and raised it up to the right height while waiting and then I passed and got my mod permit. The mod permit says I have adjustable suspension and that the car must maintain 100mm ground clearance.

1) as long as it fulfills the requirements regarding ground clearance (>100mm), front and back arrival/departure angles, you do not decrease the damper stroke length by more then 1/3 travel and its not riding on the bump stops then you will be fine - to be safe, raise it to an amount greater then 100mm ground clearance - say 120mm for safety sake

2) no you do NOT need a permit for coilover suspension modifications AS LONG AS the suspension replacement parts were designed FOR THE CAR YOU ARE PUTTING THEM ON (ie retro fitting honda parts to put on your nissan is a no-no, technically so is putting silvia parts on your skyline or vice-versa, but putting coilovers designed FOR your model skyline on your skyline is fine)

if you want to get more info then read the National Code of Practice documents, VSB 14: NCOP11_Section_LS_Tyres_Suspension_Steering

As Hanaldo said, this is a big misconception when it comes to engineering certificates. The purpose of an engineering certificate is to confirm that a car is safe if you have done a none factory modification. For example, if you put an LS1 into your R33, you should have a engineering certificate to say that the car can handle that engine including brakes, suspension, chassis etc.

Illegal modifications are illegal no matter what. If your car is below 100mm, then it is an illegal ride height. No engineer will sign that off as it is against regulations.
