hi all the time as come to replace the front discs and pads on my car at the moment it is standard 288mm discs i was thinking of upgrading to the 312mm discs i know its the same calipers and pads but what i need is the larger caliper carriers do any of you know where i can buy these from and roughly how much i can expect to pay . also as anyone done this upgrade and is it worth it i have already got 17" wheels on so there is no issue with clearance so i thought as i have to buy discs and pads it would be a good time to do it your thoughts would be very much appreciated
