Grooved Brake Discs

[Swiss_Toni]

Might anyone have a source for GROOVED break disc to replace the AP cross drilled ones?

I had thread ages ago where I could get some made but I couldn't find enough people for the minimum order.

Doesn't AP have any in their catalogue?

Be careful here, I have Hi-spec monster calipers and 360mm discs fitted and while the larger diameter disc has some obvious advantages, don't lose sight of the penalties in the un-sprung weight dep't. I think mine are about 1.5 Kilos per corner heavier than std. fitment AP!!
You won't get 360mm into a 17 inch wheel but just in case you were thinking of going bigger.

Just following up in case anyone else is looking for these.

Some one PM'ed me with a heads up for some from Schwarz Performance.

I've ordered them and have run them at Brand Hatch for a couple of days and found them to work well.

The only comment is that the bolt fixing kit wasn't as good as expected, but that probably me being fussy.

AP CP3581's are the best bet. We sue them in place of the cross drilled discs as they are a lot stronger and less prone to cracking
