Product Details

Rennline's replacement front spoiler is a direct-fit upgrade for OEM part 91150305501, restoring your 911's original look and stance with modern durability. After decades in a high-impact area, factory spoilers often suffer from curb rash, cracking, sun fading, and brittle mounting tabs. Rennline solves these issues with UV-stable, impact-resistant materials for a longer-lasting fit and finish. Designed to install using factory hardware, this spoiler arrives ready for paint and brings your classic 911's front end back to life with factory-fresh precision.

    Nice replacement

    Just finished installing this on my 1988 911 (G-body) and am overall very pleased. You’ll need to take the front valance off, prepare to bust some knuckles, and probably use a little profanity. The bolt on the passenger side is especially difficult to access, but you will prevail eventually. I struggled a bit using the original hardware since the Rennline piece is much more rigid than the factory spoiler, but all the holes lined up correctly. I ended up using new M6 hardware with M6 fender washers on both sides of the mounting points. I did re-use the original barrel hardware that goes inside the spoiler holes, along with the original white “dog bone” pieces on the ends. Start in the middle and work outward. The end result looks fantastic and really cleans up the front profile. Like most jobs on an old 911, I could probably do it in a quarter of the time the second time around.
