I have a set of fiberglass bumpers available, due to an abandoned project. They are for 930/turbo flares and are in the style of the RS 3.0/IROC cars.
Front bumper is used, but in good condition. This is the style with an integrated splitter running along the bottom, which I think gives a more purposeful/race look than the stock RS/IROC design. It has a slit for a tow hook (I think the style which uses the front bumper shock mount). It also has a hole under a signal housing socket, which needs to be patched. It comes with a metal grille over the oil cooler inlet. Not sure who the manufacturer is, but someone suggested Getty.
Rear bumper is new and has been in storage for a few years (made by Better Bodies). It is in primer.
$600 for the pair, collected in San Diego.
The red car below (by Paul Rodelo) was the inspiration for the bumper choices (the front bumper looks identical).
