i would totally agree with Ronnie on this, go with the std book spec uprights & if fitting discs then use an adapter plate to alter the angle of dangle so to speak,
Tho i would like to say that the Roadster behaves perfectly well brake balanced with drums on the rear, Spud69,s car has drum rear brakes & the braking is superb, we went on a track day & i couldn,t believe how late Spud was braking
, totally safe & controlled,
& i,m an ex bike racer who is used to late braking on the track, for my own build i,m sticking with drums, as thats what i have from my donor.
cheers
