Lotus Elan

New UK MOT regulations

PostPost by: Elanman99 » Thu May 10, 2018 9:33 pm

Are coming into force on the 20th May 2018, Cars over 40 years from registration do not have to be tested unless they have been 'Substantially Altered'. Most of the alterations mentioned are not likely to be problematical but one area that it seems might catch some owners out is the Spyder twin wishbone rear suspension.

The new rules include this statement,
Axles and running gear – alteration of the type and/or method of suspension or steering constitutes a substantial change

Chassis change is fine, but I'm not sure about changes to geometry.

If you read further down the advisory document you will see the following

The following are considered acceptable (not substantial) changes if they fall into these specific categories:

• changes that are made to preserve a vehicle, which in all cases must be when original type parts are no longer reasonably available;

• changes of a type, that can be demonstrated to have been made when vehicles of the type were in production or in general use (within ten years of the end of production);

• in respect of axles and running gear changes made to improve efficiency, safety or environmental performance;

• in respect of vehicles that have been commercial vehicles, changes which can be demonstrated were being made when they were used commercially.

I think that covers any Spyder suspension conversions, although it may start a lively “discussion” regarding efficiency, safety and environmental performance of Lotus vs Spyder suspension :mrgreen:
Kindest regards

You could argue a Zetec conversion qualifies, because it improves efficiency and emissions.

In other words, Alan, I think you're in luck. :D
