i want to fit my front splitters myself and was wondering wat tools il need. are they held on by screws or by tiger seal etc? any help greatly appreciated

Depends on the splitter you get.

My old 'indy' one was held on with screws at both ends in the wheel arch and tiger seal all the way around the front to the original bumper.

My new one is a full bumper and just uses original screw fittings
