Come on let's please be sensible rather than black & white, I do openly confess it is a modification but I'm by no way drastically changing the vehicle.
It’s one of them really, some people like to make small or even large modifications to their cars and it never becomes a problem, until there is an issue with either a large warranty claim or especially in the case of a large insurance claim, like total loss.
You could be offering the opportunity for the claim to be rejected, straight on a plate.
With regards to insurance claims, I very much doubt that an owner would be penalised for fitting muds flaps to his / her car, but other mods that could potentially alter the steering geometry could be seen as a different matter.
I have had a slight tint done on the glass on our car from the “B” pillar back.
This could be regarded by some, as reducing the visibility through the glass, therefore I have declared it !.
When completing the insurance application form, you reach the section where it asks :-
“Has the vehicle receive ANY modifications or deviations from the factory supplied spec’s”.
You have to be 100% truthful here or having insurance that has NOT declaring these mod’s, is a complete waste of time & money.
If you have any mod’s, this is the time to be upfront and declare them !.
I was NOT charged an additional premium for adding the tint, but it is itemised on the policy.
Would you be happy to receive a refusal of a large warranty claim or a total loss claim on your almost £30,000 car for the sake of gaining 15mm increased width on your car, by installing wheel spacers ?.
I thought not !.
At the end of the day it’s your car, to do what you like with it.
The insurance issue can be resolved by declaring them on the policy, it’s the warranty issue that’s the risky one ?.
Would the dealer notice, would they even care - who know’s ??.
You could always remove them before it goes in for service or any warranty work I guess.
