I’m often asked for accurate F1 steering wheel Dimensions. So I have drawn an accurate PDF drawing of a early 2000’s F1 Steering wheel. Based on some silicone moulds I aquired, taken from the original tooling. Although in the drawing, I’ve amended the wheel to have the mandatory MES dash module fitted. This dash module is detailed on the McLaren Electronic Systems Website (http://www.mclarenelectronics.com/mes_pdf/Unit_DI_PCU-6D.pdf). The PDF of the wheel is drawn at 100% scale, and fits onto a single A4 sheet, the wheel being some 291mm wide.
If you make a replica of the wheel, then please send me pictures of your finished work.
