Cutting grooves in standard vented discs...

[jondee86]

Looking at a mild upgrade for the front brakes on an AE86. I have a set of new
OEM style front discs and remember someone telling me a few years back, that
there was an engineering firm somewhere in the Hutt Valley that could groove
discs. If anyone has a line on what company that was, I'd appreciate the info.

Gonna run Hawke HPS pads front and rear if it matters.

Cheers... jondee86
