Review on 🚗 Jaronx BMW Pedal Covers - No Drill Anti-Slip Aluminum Gas Brake Pedal Cover Set (Compatible with BMW 3 5 6 7 X3 X4 X5 X6 Z4, E90 E91 E70 E71 F10 F11 F01 F25 E89) by Ryan Fuhrer

They really matter! I just installed them so can't comment on their durability but they look great and are very easy to install. All you have to do is install the throttle above the pedal. One for the brake. Be sure to remove the rubber grommet that was already installed. I see someone posted about how hard it was to put it on the brakes, they obviously didn't remove the rubber from the brake. I would give it 5 stars but I had a tiny gap in the accelerator pedal. You shouldn't send it back for a new one, it's almost invisible. Considering the price, I would still buy a new kit every few years.
