- Available for the 2016 season...

For the first race for 2016 we have invited Tim Gray to drive our prototype PR3. Tim will be giving detailed feed back to see what further improvements we can build into cars number two and three which are currently in production.

Originally designed by John Kirby - the name behind the ultra successful JKS/Speads in the UK - the PR3 has been further developed by ProFormance Metals Ltd to pass the stringent MSA 2014 Roll Hoop Test on behalf of DSE.

Created with club level single seater motorsport in mind the PR3 has been built to take a variety of power units via a choice of rear chassis sections, yet the PR3 remains simple to maintain and most importantly, an intensely satisfying drive.


The PR3 was the first steel frame chassis to meet the new 2014 MSA / MIRA Testing Standards.


Because of it’s two piece chassis design the PR3 is able to accept a variety of both Bike and ‘conventional’ Car derived power units (up to 300BHP) when coupled through a sequential transaxle gearbox. The PR3’s flexibility makes this chassis suitable for a multitude of race of championships through-out the world, Monoposto in the UK, F1000 in both the USA and Australia. The PR3’s low drag/high levels of mechanical grip characteristics also make it an ideal Hillclimb or Sprint car for a variety of classes with either Bike or car based power units.


The PR3 rolling chassis is available from just £20,500 + vat (less if you want to build the car yourself) with complete ‘ready to race’ cars available with our favoured GSXR 1000cc engine, or a 1450 cc Hayabusa from just £26,000 + vat. Low Cost Maintenance – Although almost every part for the PR3 is bespoke and made from the finest quality materials the cost of spares has been kept to a minimum. The PR3 is simple to maintain and is supplied with a full maintenance manual.


The chassis’s neutral handling characteristics combined with high levels of mechanical grip ensure the car is both entertaining in experienced hands whilst remaining a safely predictable drive for novices.
