Yeah ive heard many road racers use drums on the rear. unfortuanely mine comes with disks on the rear
My wheels are amongst the lightest ( 8.6lbs ) for 15" x 6.5" isnt bad eh
although they probably arent the " cleanest " regarding aero
aerdynamics will be the next step - however i want to avoid using rear wheel skirts, although a full undertray would be great ( but not at the moment as im still sorting out suspension + welding a few bits and bobs )
Id also love to do a " race " mirror conversion / motorbike mirrors but i park on te street and im afraid someone would " borrow " these for their car.
As i said i plan on deleting the rear wiper and wing ( although still uncertain whether or not the spoiler helps aero )
Chances are i may do a 1/2 rad block as ive seen a lot of these cars running half size rads anyway.
