Maybe not making it clear enough. Its a full track car, no interior or airbags and decated etc.
Other than the decat, the other stuff shouldn’t matter.
I had my fully roll caged, no airbags, ABS removed, supercharged clio MOT’d at a Vauxhall main dealer for 3 years 😂
If the question is, I have a non-road legal car, that I want road legal, then the answer is make the mods fit with the DVSA regs and talk section 13 of this through with the MOT station in advance;
Definitions, vehicle classes, reasons to refuse to test a vehicle, narrow track vehicles, historic vehicles and inspection procedures for car and passenger vehicle MOT tests.

If the MOT station doesn’t really understand the above, and seems hesitant to talk through your needs, ring some more until you find one that has experience of MOT’ing track vehicles.
If the question is, can someone steer me to a hooky MOT place, then asking on a public forum probably not the wisest move.
