I'm looking to replace the brake discs and pads all round on my 2006 A4 3.0 tdi quattro 233 (chipped to 294). Having priced up Brembo OE spec replacement parts, the whole lot comes to just shy of £300. Are there any other decent brands that are worth considering? Should I be looking to go for upgraded drilled or grooved discs? Thought I better ask on here as you lot will surely be in the know!
