Hi guys.
I open a thread some time ago at pistonheads, but they recommend me to come here.
I'm building my own race car, a motorcycle engined single seater, and I would like to make it road legal and I have some questions about how do it in the easy and cheapest way possible.
I must say that I'm not from UK, but I will be there probably in a little bit more than a year there, I hope, with my car finished.
My idea is to take form a motorbike: the mirrors, horn, engine, and lights, so I will be close to be "road legal" with all of this things.
I will use some things from commercial vehicles, like the transmission shafts, and the differential.
I was reading the regulations about the IVA, but I have some doubts about:
My problem, is that i don't know what kind of homologation is the best to me, so i would like to ask you about that.
I think because of some reasons the best one is "Vehicles manufactured using parts of a registered vehicle".



Maybe its easier, and less restrictive, OK, but it sais that I need at least, one of the following components: "chassis-body-suspension-transmission-steering assembly- and alxe, or the engine".
Lets say, I build my car, and I have my transmission shafts from a comercial vehicle, is this enough or i need to have the whole "component".
How can I tell them that this parts are from a comercial vehicle, and I'm not cheating? May I present any kind of documentation about the engine or the parts from the vehicle?



Kind regards, and thanks beforehand.

Unless you are a company, it will be an amateur built car.

amateur built car

In the UK you are very free to make your own car using a mixture of commercial or home made parts, the components are effectively free provided you meet the safety criteria, sharp edges, position of mirrors and lights, steering action, braking and lights.

If it's made from mostly brand new parts, there is a scoring system you can get an age related registration (restrictive on emissions) or it will be awarded a 'Q' plate which indicates which is a lot easier to achieve a pass on however the plates is not transferable and stays with the vehicle.

The car then does not need to be recognisable as a standard car, an Aerial Atom clone for example is fine, we are lucky to still be able to do this

You do not need to worry about using standard components, some parts such as lights have to be correctly marked however with the relevant EU numbers.

Thank you a lot for the fast replies!

Mark, where could I find this score system? I tried to find it, but i couldn't.

I think I would be interested in these kind of age related registration, for sure, It will be easy so pass the emissions.

Yes, I know that i need the EU number on them, but If I'm going to use parts from cars for this, I hope don't have any problem.

Thank you Guys!
