I have a 2022 Lexus IS300 2.0L RWD F sport, which has the exact same bumpers as the is350/is500, which means that this lip fits almost perfectly! It uses existing screw holes to hold it down in the centre. On the sides I assume you are supposed to drill into the bumper, my car is a lease so I chose to use double sided tape instead which actually worked quite well. The only reason that this did not get 5 stars was that there are no instructions (even though it’s pretty simple to figure out yourself), and the plastic it is made out of feels to be quite cheap. In daylight it appears to be dark grey, at night it looks more black. Personally I would give it 4.5/5 stars, and would highly recommend it to anyone who is looking to add a real lip to their car for a decent price! (Under $150). We’ll see if it can withstand a Canadian winter though. Time to scrape some curbs !
