Track Titan: 1975 Porsche 911S, RSR-Style Conversion and Vintage Racing Legend: This 1975 Porsche 911S, transformed into an IROC RSR-style race car, is a testament to dedicated track performance. Modified in the mid-1990s by Cox Racing and further refined in 2018 by Huffaker Engineering, this 911S boasts a comprehensive RSR conversion, including a fabricated strut tower structure, tubular steel roll cage, and a FuelSafe fuel cell. Refinished in a striking blue with Bobby Unser-inspired livery, this race car has participated in numerous PCA, SCCA, and HSR events, accruing approximately 121 on-track hours since its 2019 refurbishment. Featuring a rebuilt 3.0-liter flat-six engine and a recently rebuilt five-speed manual transaxle, this 911S is ready to dominate the track.
RSR-Inspired Transformation: Track-Ready Aesthetics: The IROC RSR-style conversion by Cox Racing and Huffaker Engineering has resulted in a visually stunning and aerodynamically efficient race car. The blue paint with Bobby Unser-inspired livery, applied by Motorsport Solutions, pays homage to racing history. Modifications include covered headlights, hood pins, Lexan windows, flared fenders, a “whale tail” spoiler, and a GT-style rear bumper. The car’s lightweight construction, approximately 2,100 lbs empty, enhances its track performance.
3.0-Liter Flat-Six Power: Track-Focused Performance: The rebuilt 3.0-liter flat-six engine, overhauled by Wayland Motorsports with Mahle pistons and a GT3R main bearing set, delivers robust power and reliability. Dual PMO carburetors, an Electromotive direct ignition system, and tubular headers contribute to the engine’s performance. The recently rebuilt five-speed 915 manual transaxle, with a cooler and Weldon 9200A differential pump, ensures optimal power delivery on the track.
Track-Tuned Suspension and Brakes: Precision Handling: A comprehensive suspension overhaul by Wayland Motorsports in 2021 included fabricating camber plates, installing an adjustable bump-steer kit, and fitting RSR front strut assemblies and Racing 934 rear shocks. The 16″ wheels, with BBS two-piece barrels and Fuchs centers, are fitted with Hoosier R7 racing slicks. Porsche-branded calipers over cross-drilled and ventilated discs provide exceptional stopping power, with adjustable brake bias.
Stripped Interior and Racing Equipment: Driver-Focused Cabin: The stripped interior features a welded roll cage, a Sparco racing seat with a Sabelt multi-point harness, and a FireSense fire-suppression system. A quick-release MOMO steering wheel and VDO instrumentation provide essential driver feedback. Auto Meter auxiliary gauges and vehicle control switches are mounted on the metal dashboard. A custom-made passenger seat with a Schroth Racing harness is also included.
