Working with Simon McBeath, aerodynamicist, author of the Haynes published "Competition Car Aerodynamics" and the "Aerobytes" column writer for Racecar Engineering magazine, ADR spent a day at the MIRA full scale wind tunnel on Friday 21 January 2011.
You will be able to read a full report of the MIRA testing in Simon's column in www.racecar-engineering.com Magazine which is scheduled to run from April 2011 to July 2011.
With a lot of work and forward planning from Nick and Ben at www.carbonweezel.co.uk , prototype parts were produced which enabled a series of 50 test runs over this very hectic day. The emphasis was to achieve aerodynamic downforce figures to a near 50/50 split front and rear at around 90MPH.
Obviously we could have looked for the highest downforce figures at 150MPH, but took the decision that the average cornering speed is where this force is required.
After 37 runs and various changes we achieved a split of 47.4% front and 52.6% rear,and an L/D of -1.887,which we are all very pleased with.

Following these successful tests we are pleased to announce that from the end of February 2011, we can offer a full Aero update kit to all existing ADR3 customers and as a 2011 promotional offer, the first 3 cars of any model ordered before 28 February 2011 will be fully updated and receive full MIRA data sheets at the 2010 price.
