Since I keep getting asked about size, here is the quote from Korman's website.... (yes, they provide more room than Alpina style and Turbo.)
"Lightweight Fiberglass Parts
Fiberglass provides several advantages: light weight for quicker acceleration and cornering, special shapes for customized appearance, and no rust. Our fiberglass is hand laid and carefully reinforced for stiffness. It is finished in a smooth gel coat and ready to wet sand and paint.
The Alpina Style Flares present a smooth rounded appearance. The Schnitzer Style is more angular and similar in appearance to the E30 M3 factory fender flares. Both types are wider, allowing the installation of larger tires and wheels. Depending on offset, ... 8.5"-9.0" rim width is possible with the Schnitzer Style Flares."
