groves vs drilled discs

I would opt for grooved, they offer slight pad cleaning advantages and the holes often crack on drilled disks.

Grooved also sound cool braking from high speeds :-p

 

^^^ Exactly this...

Although J hooks are better than grooves

Shameless plug.

 

Do you do these discs for the rear of a 250 as well as front??

 

Drilled look better if your not going near a track

 

Planning on release some in the next 4-6 weeks.

 

I thought the R26r grooved discs were prone to cracking not the r26 drilled?

 

Nope it's the holes in the drilled discs.

 

Well fred at BTM and Yoz always used to say the R26r discs were worse than the drilled ones on the R26, there were a few people who made warranty claims through Renault UK for replacements too.......

Looks like they've had issues with both. The R26 discs do this
