depends alot on your planned usage of the car and your driving 'style'
you going to be doing any track days etc?
the good folks on here, recomended some pagid blue pads to fit the std 312mm discs, which by all accounts are great if you plan to go no further. or Nathans set on here that are also good value
But if you then decided they werent sufficient then its probably not a good investment.
going to R32 fronts (+ optional rears) , then up to proper big brake kits are steps up from that ....
I went for R32 fronts from DaveB on here, which performed faultlessly at Oulton Park.
the solution depends on your requirements
