But remember...it's your brakes you are speaking about!
Cutting corners, buying scrapyard specials of unknown providence then lashing a set up together and expecting it to work, can be a short exercise in living.
If anyone genuinely wants a brake upgrade...they should do themselves and other road users a favour and buy a TUV approved (or similar) well proven, reliable, kit.
At least you know the calliper seals are good and it's unlikely to cost you your car or life.
I know £950+ isn't cheap...but what velue your car or life...if you 'need' better brakes?
Same goes for cheap-*** 'no name' maker std discs and pads...not for me.
I'd rather buy something from a proven manufacturer who's knowledge and expretise (and back up) will give me the results I want.
So you have to pay a few quid more...
But I'd rather live to pay a bit more, than suffer the consequences of fitting cheap, poorly designed, poor quality or miss-matched brake components to a 1400 Kg 150 MPH car.
