Installation reasonably straightforward - the accelerator pedal is wider at the base than original so you need to be mindful to leave enough room for the mat to slip under it.
I stuck them on with double-sided tape then used a 2.5mm to drill sighting hole - then a 4mm - which is slightly smaller than the imperial bolts provided, and they self-tap nicely into both the plastic clutch pedal and metal brake pedal faces. I put nuts on back of brake pedal anyway even tho the plate won't be going anywhere. Can't really get nuts on back of clutch pedal but not necessary as long as you don't overtighten.
Clutch and brake plates are very grippy and have a nice curve to them. A worthwhile improvement alone from a functional perspective - plus they look great. I have a black interior so a bit of bling also enhances it cosmetically.
