Very interesting document this is above. As of the 3rd November a revision was made to light vehicle modifications. Outline of this document states what can pass through with or without a certificate on the mods done to your car.

* Engine
* Performance
* Suspension & Handling

OR even just cosmetic additions

Worth a read.
