Bit harsh.
Did they say they would void your policy if you did this, or that the policy just wouldn't include your suspension?
Do they know about your alloys lol?
I'm pretty sure at least 80% of car owners that modify or alter their cars don't tell their respective insurance companies.
You could be naughty and do it anyway, and if you do have a situation where you need to make a claim, don't expect it to be a succesful claim
I wanna mod myself but don't think I realistically should, as I doubt my insurer [ASDA] would be too happy. I distinctly remember on the day I took it out that they asked is the car completely standard, to which I obviously replied yes... :boring:
