These aren't mass-produced eBay specials. Born from track-day demands, our 1/4" gloss black end plates bridge the gap between showcar shine and track-ready durability. Unlike flimsy ABS or foggy tinted acrylic, these use UV-stabilized cast PMMA—the same material used in racecar windshields. The pre-drilled slots were tested on 7+ spoiler designs, from APR wings to eBay universals. No fitment guesswork—just bolt-on aggression.
