Whats the best combination for heavy road use? I'm unlikely to do much track day use, so which would be the best combination? I prefer the look of just plain or grooved disks, what are the merits of getting drilled and grooved exactly?

cheers

Get grooved only, I have drilled and grooved, I like to use the brakes, hence my discs are covered with little cracks all over, Grooves clean the pads, the drillings just look good!

the drilling helps to cool the discs better.

i thought that would be the case; the ferrari disks i've seen are drilled only, i think grooved might be the better option plus i prefer the look

I fitted Diamond grooved discs to a previous Mondeo (don't laugh it was a V6), they were better than the standard, but very noisy!
They made a grinding noise whenever used, so I am wary of grooved discs for that reason.
Anyone else get noise with grooved discs?

No noise at all with the Scoobysport Grp N+ (Pagid) discs

Just grooved... I was told by Hi-spec that because the impreza is a heavyish car and really does hammer it's front brakes that X-drilled will be liable to crack, or warp dir to the problems with heat dissipation (apoligeez if spelt rong!!)

Ive got grooved Red Dot discs on my RA, brake hard from high speeds and it sounds like an underground train slowing down.
Doesnt bother me now though, i got used to it.

Mine are the 325mm Godspeed ones. I took advice from Ian, and since I don't do track days, have drilled and grooved, and no probs so far.
The only noise I get since I used the bits Ian gave me to cure rattly pads, and squeaky pads, is a sort of pattering noise from the grooves, certainly not invasive.
