lol .Thanks for your valuable suggestion sir. Yeaahh i am also thinking to pick one of them.Too wide, I wouldn't risk any modifications to ruin a perfectly fine 8th gen mugen spoiler.
I hope you know mugen spoilers to begin with are very expensive, let alone almost anything mugen.
The best spoiler IMO is either the m3 trunk lip or the 96-98 OEM spoiler because it also has a functional brake light and isn't a high-flying wing to make you improve your aerodynamics and gain 50HP and pick up all the ladies.
