I think a much bigger downside would be its effect on the price of your insurance. I can't speak for any other country but in the UK insurers have a reputation for being petty about modifications. Even something as minor as a DIY heated seat switch would have to be declared to your insurer who could refuse to cover you or charge a silly premium for cover.

That's a U(k) problem not a me problem. Here people put their cheap base model pick up truck on the highest, cheapest, Chinese lift kit that money can buy with no real effect on the price of their premium. You only pay more when you want to insure the cost of the replacement of your modified parts, which very few people are going to bother doing.
