Hey, I wonder what would be the best way to upgrade my BB1's Front Brakes!
I could get ATR ones fo 60 bucks and i guess mtec would make the 300mm 4x114 discs for a cheap price. What do i need to do to fit them? Or is a EP§ brake the better choice however? Or any other suggestions?!

For budget, I would just stick with OEM grooved/slotted disc with good pads (Ferodo DS2500).

After that I would step up to ATR callipers/carriers so that I could use 300mm Discs with OEM pads..

And after that I would get Performance ATR brakes/pads.

I think Liam on here, got Ep3 brake set up on his car but not sure if it was cheap.

mtec 300 mm discs and either Atr calipers and carriers or ep3 type r calipers
