my car also has lip
installed by myself this afternoon. took me about 2 hours, bro was too busy pushing out the ZZZZZZs on the lounge so had to do everything myself. would have been a lot easier if i had ramps so it would have been easier to drill holes and see what i was doing. only used a drill, screwdriver, black marker and the jack from the back of the car. ended up being pretty straightforward to install, was just very fiddly holding the lip and lining up where i had to drill. a big thanks to Mick (PHATGT) for getting me the lip.
