A sticky end
Having previously raced his 3.2 BMW M3 E46 in the UK’s Kumho BMW Championship and the CSCC New Millennium series, after sampling a Britcar Sprint race late in 2018 Piers Reid has now moved into the Britcar Dunlop Endurance series. We took the car to the MIRA full-scale wind tunnel to optimise its aerodynamic package.
As ever, the first runs in our session were illuminating. Planning, however, had allowed for most likely eventualities and a raft of modifications were made. The owner’s primary objectives were to reduce the drag and also improve the aerodynamic balance. By the session’s end we had achieved high downforce and low illustrates. Wing angle reduction and splitter end fences played key roles in early runs, as we highlighted in last month’s issue, and from there we examined further front end changes to modify the aerodynamic balance.
