are two different types of car modifications and both are likely
to have an effect on your car insurance premium.
An insurance company is likely to view any aftermarket change to
the car away from the standard (how it rolled out of the car assembly
factory) as a modification.
must make sure you declare and tell your car insurance company about
any modifications you make to your car as if you do not declare
them and you are involved in an accident you run the risk of having
your car insurance invalidated.
Cosmetic modifications include things such as alloy wheels, body
kits, spoilers, ICE (In Car Entertainment). Although not necessarily
making your car faster they may make it stand out and become more
"attractive" to thieves or vandals. This in turn means
there is a higher risk to car insurance companies to insure it.
Performance modifications are pretty straight forward. They are
any modification that is going to improve/increase the performance
of the vehicle. This includes things such as lowered on new springs/suspension,
exhaust, induction kits and any other engine tuning modifications.
The faster the car can go may increase the likelihood of an accident.
