Build pitfalls

[sambo]

Turnips, so long as your lights are "E-marked" they should be OK. The changes to seat height took effect half way through last year so any new cars need to comply. If your seat manufacturer provides the correct paperwork you should be fine. Eg, evidence of having passed the relevant ADR test - your engineer will clarify.

Depending on which kit you purchase and the state where you engineer it, you may need to provide evidence of twist and bend tests. For high volume kits such as Harrison, CR, G-Force etc, most engineers will accept evidence of testing on an early chassis provided the design has remained the same. Again, seek clarification.

Brake and/or lane change tests, your engineer may accept evidence of testing another kit from the same manufacturer, however it varies state to state. If when they drive your car it's not properly wheel aligned or your brake bias is incorrect you may trigger alarm bells so make sure that's all sorted before they jump in.

If you present for engineering with evidence of a soft top or hardtop being fitted you may need to meet additional ADRs - I believe an effective windscreen demister is required.

In the past, some states required 3 windscreen wipers but I think it has been relaxed so long as a minimum swept area is met. Again, see your engineer.

Brightwork is another one. Shiny chrome steering wheels, reflective mirrors and such - may be seen as distracting to the driver. Rear vision and side mirrors need to be ADR compliant, correct dash padding needs to be fitted.

Please don't take what I've said for gospel. I think it shows that when added together, lots of little requirements can amount to a big headache and many people don't realise this when they start the build. Develop a good trusting relationship with your engineer and it goes a long way.
