I don't see the need for drilled or grooved disks for road use, or maybe I'm too old & slow

... and drive a diesel
the hill that leads into my town is big... I pop it into neutral on the moor & ride it down for two and a half twisty miles to sea level... large sections of it are an 12% gradient - top laugh on an empty road

- coming down off the moor on the way to work is dual carriageway - pop it into neutral at 60 mph at the top and come out the last corner and feed onto the motorway doing over 90mph still in neutral - man I LOVE gravity
I just have 238mm vented on the front & drums on the back with cheap pads - although the disks and the master cylinder etc are only a few months old at most.
even at the bottom when you can feel the heat radiating off the disks from like a foot away (& dumbass here actually licked his finger & touched the disk

ouch!) - no particular fade, still nice and responsive - the only thing I'm going to do is fit greenies & braided hoses. - it really does not need any more for road use IMHO.

mind you big brakes do look sexy, but i'm too tight to get anything that isn't functional & preferably cheap or secondhand :embarassed:
