Noodle :hiwelcome: Mate, most kits will void your waranty on engine and driveline components, so if in doubt , dont mod your car. In terms of insurance , some will cover you , but there are a lot that wont. Try AAMI , I found them really good to deal with , and mods are no problem as long as you include them on the policy. You must let your insurer know of any mods, as if they are discovered subsequent to a claim and they are not on the policy you wont be covered. Anyway do a search on these topics as there is plenty of info avaliable. BTW whatcha drivin ? Welcome to the site and enjoy the community WhiteTee
