Race Car Vehicle Dynamics  



"I was sceptical that Nigel could

improve a car as my Lotus 18 but the

car was two seconds a lap faster at

Snetterton and muchmore positive

to drive."


- John Hutchison   



Martin Stretton - Lola T70 Mk 3B and many other cars

"Nigel's work has repeatedly provided a huge cost saving with chassis development when his recommendations have been applied to cars I have tested. The correlation between Nigel's analysis and what I feel the car actually doing on the track is quite remarkable. In addition, the CFD work James (Ayari) carried out on alternative aero configurations enabled us to maximise performance in a very short space of time"

Lola Mk5A Formula Junior – James Murray


For over two years we have struggled with power oversteer and poor traction, which meant that our Lola was unpleasant to drive – and was not the front runner we thought it should be. GSD RaceDyn conducted a full computer based engineering analysis in early 2010, supplying a detailed 7 page report and recommendations, for £985. We implemented all GSD’s recommendations and GSD attended a test day at Cadwell Park in April. Traction and handling balance were vastly improved. The car lapped 3.7 secs faster than we had previously achieved. Business pressures limit our programme, but the car has been a consistent frontrunner in FJHRA and a winner in FIA Lurani Trophy events.

1982 Arrows A4 Formula One – Steve Hartley


We race a pair of ground effect Arrows A4 F1 cars in the Grand Prix Masters and FIA Historic F1 series. Competition is becoming increasingly stiff and we felt that we weren’t extracting all the potential from the cars. Nigel Rees (GSD RaceDyn) undertook a full engineering analysis and ran simple, low cost - but effective - aerodynamic tests on an airfield. GSD gave detailed recommendations. The cars are now substantially faster and much nicer to drive. The improvement in high speed corners is awesome. Against heavyweight competition, our 2010 -12 results included an outright win at the 2010 Silverstone Classic, a win at the 2012 British Grand Prix FIA Historic F1 support race, a win at the Nurburgring and pole at Donington and podiums at Spa and Nurburgring. GSD also run simulations for us before every race, which means that wing settings, suspension settings and ratios are optimised in advance – very important because we are generally unable to test to buy the best cheap replica designer handbags.

Malcolm Paul - Lotus 10, Elva Mk5, TVR Grantura, Chevron B8

Implementing recommendations from Nigel and GSD RaceDyn has resulted in significant performance improvements on cars as diverse as my Lotus 10, Elva Mk 5, TVR Grantura and Chevron B8. All have achieved wins and the cars are now much more pleasant to drive.
