Hi all, I am looking for a pair of 4 pot calipers to upgrade the brakes on a car i am building for track and hill climbing, I understand that there are modern ones that have the same footprint as TR6 ones can anyone help with the type make etc. Or does anyone have any to sell. I am looking to pay around 100 pounds for a pair i don't mind if they need refurb. I understand the cost of new ones are high which is why i'm looking for ones to refurb. Cheers in advance Andy.
