Porsche 911/991, 991S, GTS, targa, GT3 Magnetic Stone Guards

from $125.00

Help protect your Porsche 991 from rock chips while giving it that classic retro style with MagnaFin “shark fin” magnetic stone guards. These are not your average easily scratchable black vinyl stone guards. MagnaFins are made from 30 mil High-Energy magnetic material with an additional clear layer of protection and a gloss backcoating on the magnet side to protect your paint or PPF. Goes over factory clear stone guards or paint protection film. Install or remove in seconds. Track tested at go-to-jail speeds. Sold in sets of 2, one driver’s side and one passenger’s side.

Please specify wide body or narrow body when ordering. The narrow body size fits great on the wide body, in fact Porsche only make one size clear stone guard for both. But we have a custom shape for the wide body cars that covers a bit more area.

Options:

Deep Black: A deep, rich black with a clear, matte, UV protective layer. Matches the OEM texture on 991 exterior black plastics like side skirts and the rear diffuser. $125

Printed Black (matte): Printed black on a white surface with a clear, matte, textured UV protective layer resulting in a matte black finish. With or without logos $175

Carbon Fiber: 3M carbon fiber provides an extra layer of protection $175

Note: This is a hobby/side hustle/labor of love. MagnaFins are usually made-to-order, with some inventory in stock. Please allow two weeks for out-of-stock or custom orders. Email to confirm availability and discuss custom orders.
