This is a complete setup for the Geartronics paddleshift system

• Geartronics director, Neil Wallace, in his flying Sunbeam during the Jim Clark rally many years ago!
• A typical paddleshift wiring harness - this one was made for Quaife's Caterham demonstrator car. We can also build looms to full MIL specification using Raychem 'system 25' sleeving, spec55 wire and Deutsch connectors
• The Geartronics sponsored Darrian of John Harland
• CR1 sportscar from Denmark, fitted with Geartronics paddleshift
• Another view of an Aquila CR1. This car goes every bit as good as its fantastic looks!
• Keith Cowie's fearsome 1200+bhp Nissan Skyline drag car featuring Geartronics automatic shift system on an OSgiken gearbox. The car has completed the 1/4 mile in an ET of 8.4s at a terminal speed of 169mph
• The Durango Lola B02/50 formula 3000 car fitted with Geartronics paddleshift. The driver is Omar Leal, winner of the 2008 Italian F3000 championship
• Geartronics director Neil Wallace and the futuristic Citroen GT concept car, we can't say too much about this one!
• A P1-2-3 for the Geartronics paddleshift at Mugello
• A Gould GR55 hillclimb car undergoing paddleshift wiring loom installation
• The famous Zytek KVF3000 450bhp engine as fitted to the Formula3000 B02/50 Lola's
• James Hoseason's awesome Darrian uses Geartronics paddleshift.
• A paddleshift installation on a Honda Fireblade gearbox fitted to the Reynard Inverter. Note the gear position sensor fitted externally on the gearbox - an absolutely essential addition if any paddleshift system is to work!
• 'Wallace Menzies' DJ Firestorm hillclimb car. This car uses a Cosworth XD engine revving to almost 15000rpm! The Lola LT1 gearbox is of course operated by the Geartronics paddleshift system
• Geartronics pressure accumulator for the pneumatic paddleshift system
• Display unit of the Paddleshift system
• A very neat installation of the compressor, accumulator and valves by Tolman Motorsport in a V8 Star racer
• A sample data log from an F3000 car using the Geartronics paddleshift system. Note the linear acceleration trace is almost uninterrupted during up shifts. You can also see 4 down shifts in less than 1 second.
• The bespoke actuator mounted on the Lola LT1A gearbox in an F3000 car
• The OMS hillclimb car of Trevor Willis. This unique car uses a combination of a Powertec V8 Hayabusa based engine and a Hewland JFR gearbox. Needless to say, the box is operated by the Geartronics shift system.
• Rear view of a Penny & Giles barrel potentiometer. We can also supply equivalent sensors from Novotechnik, Active Sensors and Contelec
• Here are the Geartronics carbon-fibre paddles installed in a V8 Star Britcar racer
• The Paddleshift GCU - designed in-house by Geartronics. The board uses 4-layer surface mount technology
• Paddle assembly with optional carbon fibre mounting bracket
• The Geartronics stand at the 2008 Autosports exhibition
• Paddleshift installation on a Sadev SL75 transaxle
• Paddleshift installation on a Hewland FTR transaxle fitted to a Jade3
• A Hewland gear and dog ring
• The Pilbeam hillclimb car of Oliver & Sandra Tomlin. This car uses a Judd V8 engine and a Ricardo 500Nm gearbox (same as World Series cars). We had to write some specific software for this box due to the unusual gear order.
• The fearsome Porsche racer of Richard Chamberlain. Control of the Holinger transaxle is taken care of by the Geartronics paddleshift system.
• A typical paddle installation on a sports prototype steering wheel. We can supply various brackets and flippers to suit most wheels of any size.
• Some of the Geartronics paddleshift components including the all-important intelligent gearbox control unit (GCU). The GCU is designed in-house by Geartronics and runs what we believe to be one of the most sophisticated control strategies found on any aftermarket shift system.
• A special adapter designed by Geartronics to replace the unreliable Sadev sensor with a 'proper' motorsport potentiometer or hall-effect sensor. This modification is essential for anyone contemplating running paddleshift on a Sadev gearbox.
• An actuator installation on a Sadev ST90 front wheel drive gearbox fitted to a rallycar.
• James Hoseason setting a fastest stage time on his way to 3rd overall on the Manx Trophy Rally. The car is a Darrian GTR which uses a Millington engine & Hewland NMT gearbox operated by Geartronics paddleshift.
• The Reynard Inverter owned by Generation Motorsport. The Honda Fireblade gearbox is operated by the Geartronics paddleshift.
• Chiron CN class sports racer.
• Nick Algar on his record breaking lap at Mallory park.
• Peter Kukainis leading the way to a class win in the 2009 speed championship using the Geartronics paddleshift system on his Quaife 60G gearbox.
• The spectacular Puch of Austria’s Georg Pacher. Despite it’s similarity to the Fiat500 this car uses a full space-frame chassis and is powered by a Powertec V8 engine producing more than 400bhp!
