Ownership of the CC&AR system moves to XCS Designs

Following talks with the inventor of the patented CC&AR suspension system (ex-Ford Motor Company engineer, Peter Walker) XCS Designs Ltd are pleased to announce that they are now the new owners of CC&AR, its Intellectual Property (IP) and all associated manufacturing rights.

MD Harvey Rice - “My fellow director, Peter Holm, and I often talk about the first time we drove a CC&AR-equipped car", said Harvey Rice, XCS Designs Ltd’s Engineering Director. "The first thing we noticed was the system's characteristically roll-free and compliant ride - but as the miles went by, it was the amount of grip and predictability we had on tap that totally blew us away. The system's secret is its ability to uniquely keep the tyres in flat contact with the road so that all loads are distributed uniformly across the entire footprint which can then work to maximum effect. It's undoubtedly a remarkable invention and we're delighted to have been able to secure its IP and to welcome the system to its new home at XCS Designs".

The CC&AR system is used on all versions of the XCS 427 but there are significant differences. A bespoke embodiment of the system, which includes purpose-designed billet aluminium suspension uprights, is used at both the front & rear of the top-of-the-range, ‘XCS 427 round-tube’ whereas a different embodiment, which utilises Jaguar XJ40/X300 uprights, is used at the front only of the basic box-section ‘XCS 427 de Dion’.

Camber Compensation & Anti-Roll is an innovative update of the double wishbone suspension system that cleverly avoids the major camber (and footprint) compromises normally found in such systems to provide a number of significant advantages including greater grip. At the heart of the system is a straightforward linkage assembly that constantly maintains the best possible contact between tyre and road during all grip-critical modes of operation (accelerating/braking and/or cornering).

This contrasts sharply with a conventional double-wishbone system where the geometry will at best provide optimum contact in only one such mode – i.e. in cornering or in accelerating/braking – but never in both.

Other benefits of CC&AR include reduced roll, much improved composure/predictability, a higher roll centre (without incurring jacking force issues) and the ability to retain a supple ride, both for road and track.  More detailed information can be found on the 'How It Works' page.

The very first track car to benefit from the patented CC&AR system was the Rover V8 powered DAX Rush of Andy Sterling. Andy's Rush had been built as a road-going car and could sometimes be seen in and around his home town of Brockenhurst, Hampshire. But its main purpose was to allow Andy to compete in the highly-competitive Class 'A' of the 750 Motor Club championship.

The car had started life as a normal IRS Rush but about halfway through the season, Andy decided to have it fully converted to CC&AR, front and rear. From that moment on, Andy and the DAX formed an uncommonly successful partnership.


Andy gained eight pole positions out of eight and won six of the remaining (eight) races of the season, only narrowly missing out on the championship title due to two incidents with another competitor – on both occasions when in the lead. In the following year the Sterling-Rush partnership returned to make a clean sweep of the board, winning every race to take both the Class 'A' and overall 750 Motor Club titles. Even more impressively, after a 3-year break, Andy returned in 2005 to do it again!

Keeping it in the family, Andy's brother Charles then borrowed the DAX for the 2006 and 2007 seasons. While still getting to know the car in 2006, Charles exceeded his highest expectations and took the Class 'A' title at his very first attempt. He was again at the top of the leaderboard in 2007 when an unfortunate accident sadly saw the car destroyed by fire – fortunately without injury to Charles.

When asked about what it was like to drive with CC&AR, Andy said, "The effect of adding the CC&AR system to both front and rear was staggering. At Cadwell short circuit on the same tyres that I'd used 8 months previously, my lap times fell by 4 seconds! The ability to brake later than cars of 510 kg, as opposed to my 720 kg, was primarily down to the car's capacity for braking hard through turn to apex." he continued, "This allowed me to brake anything up to 20 metres later and the balance was so good that the car could be abused and always come back."


Following the success of the CC&AR system on their DAX Rush model, DJ Sportscars International Ltd extended their under-license use to the front end of their market-leading Cobra replica, the DAX Tojeiro.
