Direct brake upgrade ?

Just looked at my front disc, 35is, bit worn, so rather than put my new EBC red in, think I’ll gets some new discs, they measure 28.25 thickness for reference.
But which discs as straight fit, would like something drilled/grooved. Also like the look of the aluminium hub of the OEM ones.
Any recommendations? ..... keeping the original callipers.
 
If you want OE products tap into Autodoc your details and they’ll offer a variety of suppliers in the correct sizes..some will be drilled, all will be vented for sure..

You can go into the Wild West of the many other suppliers on eBay etc...
 
Nothing catches my eye on there, very few grooved.

I remember someone here using DBA UK brakes from Oz. Price looks reasonable, compared to say EBC etc !

Sadly Mtec don't do front discs yet, I mailed them a few weeks back, might be available end of the year. I used them on my E85, were very good value.
