I have fitted the M performance rear spoiler and had it finished in gloss black to make it look a little different to every other one. It’s so small it’s borderline pointless but ithey are inexpensive and obviously fit perfect. I really liked the 3D design ones but at £600 + paint I couldn’t justify it but thinking about it the Ford RS spoiler I bought for my Capri back in the day probably cost more!
After a year of ownership I’m still enjoying the experience and still the performance impresses me.
