i bought some mtec grooved discs and mintex pads from them on ebay for my old astra gsi i had,
the discs themselves were fine but the pads were pants (i did have 305/36- ftlb's of power mind)
if you do go for aftermarket discs go for grooved..............the last couple of times ive used drilled brake discs they've always cracked................grooved discs have always been fine for me! ( my mtec discs came with mintex pads by the way )
for the odd bit of fast road use/normal everyday driving then the mtec disc's/mintex pad combo will be fine,
they wont peform any better or worse than oem parts.............
