This January, MCR Met Racing is taking part in the ! 7 days, 7 photos of nothing but close-up parts of the car. This time we will be focusing on Fortuna, our FS2019 car that gained us 17th place in FSUK and 12th place at FSN. Take a look at our excellent designs, starting with our wheels, designed by Tom Morley
The centre-less wheel design used on the car is a part consolidation of the hub, lug nuts and wheel centre. The main reason for this design is to reduce the number of components and reduce the mass on the unsprung side of the vehicle. A reduction of 1 kg of unsprung mass is said to be equivalent to 4 kg of sprung mass, making it a desirable area to shed weight. Less mass on the suspension side of the vehicle improves the dynamic capabilities of the car.
The design resulted in a 22% and 19%, front and rear respectively, mass reduction and allowed for an increase in wheel diameter from 10” to 13”.
This year research into the use of 3D printing will be conducted to further reduce the mass of the wheels. The method of manufacturing will be Fused Filament Fabrication (FFF) with the aim to reduce infill density in areas where stress are less.
