Chris and Andy Osborne – the terrible twins – have been busy in Tuthill’s fabrication shop, fitting steel front wheel arches to this Porsche 911 RSR build.

Steel Front Wheel Arch/Front Wings 911

The most common front wing solution on widebody Porsche 911 RSR builds is using composite panels like the EB Motorsport Porsche 911 RSR front wings, which include the front wheel arch and are moulded in lightweight fibreglass. The main advantages of this approach are reasonable cost, very low weight and easily replaceable panels when things get bruised in competition.

For some of those building dream RSRs, the issue is less about cost and more about craft. Steel is solid, long standing and a rare commodity in arches for bespoke 911 builds. High-end Porsche aficionados like a complex metal wheel arch and the Tuthill Porsche fab shop is more than capable of fulfilling their wishes.

The Porsche 911 RSR build seen here is for street, circuit and rally use. It features a number of composite lightweight Porsche parts from EB Motorsport, but also a measure of old fashioned steel. It is true to classic Porsche, and to the owner, and will definitely turn a few heads when it’s finished.
