Porsche 911 Modified

Transmission

The original 915 gearbox has been completely rebuilt by Tuthill Porsche and fitted with a limited-slip differential at a cost of over £8,000 in 2014.

The car is also fitted with an M-Saver fuel cell.

Chassis, Suspension & Brakes

The suspension has been developed to match the engine specification and provides exceptional balance and precision.

Highlights include:

• Tuthill-supplied EXE-TC Classic Porsche Circuit dampers with matching springs (£6,300)
• RSR hollow front and rear anti-roll bars (£4000)
• Adjustable rear spring plates
• Refurbished front wishbones by Tuthill
• New lower ball joints
• AP Racing six-pot front and four-pot rear brake calipers
• New brake discs throughout

The result is a car that inspires confidence, changes direction beautifully and has braking performance to match its engine.

Body & Interior

Weight reduction formed a key part of the build.

The car features:

• Fully welded roll cage
• Lightweight resin front wings and front/rear bumpers
• Lightweight resin bonnet
• Lightweight rear engine lid with rear wing
• Polycarbonate side windows, rear quarters and rear screen
• New ST-style front seats
• New competition harnesses

The finished weight is approximately 980kg, giving the car an exceptional power-to-weight ratio.

Driving

This is an immensely capable analogue Porsche that feels alive from the moment you climb in. The engine is sharp, responsive and eager to rev, the rebuilt 915 gearbox works exactly as it should, and the chassis has a level of composure that reflects the quality of the components used throughout.

It is equally suited to fast road use, track days or historic competition (subject to any FIA eligibility requirements).

Documentation

The car comes with an extensive history file documenting the build, including invoices for major components and specialist work carried out over more than a decade.

Reason for Sale

The only reason for sale is a change in focus. My interests have moved towards early Lotus cars, and I have decided to concentrate on my Lotus Elite Super 95 project rather than Porsche ownership.

Finding another impact-bumper 911 built to this specification, with this level of documented investment and such limited mileage since completion, would be extremely difficult.
