drilled discs can sometimes crack.i was told for heavy track use grooved are a safer bet. as they should not crack.i suppose it depends on how well the dics is made.i have allways gone for the grooved myselfQuick question... why are grooved discs used on this conversion instead of the drilled ones that Porsche use?
If I remember correctly, that is right. It is not uncommon for vendors to use other vendors for parts and then stamp their name on them. In fact, the web spokes on the MINI are actually Ronal.are'nt the calipers technically Brembo as i think from memory Brembo make all of Porsches calipers. But yes they are porsche parts
Ahh I see. I've liked the idea of the Porsche brake upgrade ever since seeing Bhozars in the flesh but each day I park next to a Boxster S and with the cross drilled discs and they just look so darn good.
The liklehood of the drilled discs cracking is surely worth the risk though for the benefit of reducing the unsprung weight on each wheel by using cross drilled discs is it not?
After all, Brembo who make the Porsche calipers also make them for Ferrari and Maserati (MC12) which both use cross drilled discs and aren't exactly light cars so if they can hammer round a track all day surely a Mini can live with cross drilled discs?
Having swapped to TD 1.2's and AP Racing BBK I'm feeling the benefit of a reduction in unsprung weight on each corner, but I'm still hankering after the asthetics of the full Porsche kit of the calipers and cross drilled discs.

How about dimples Roland?Hi Guys, holes (even cast) always crack...hence why we use grooves...much better:smile:
