Brake Disc – With grooves instead of cooling holes
Discussion
It is my understanding the Factory have a purchase agreement with AP which resulted in the unique part numbers. AP will not sell to anyone but the factory. Makes perfect sense from the Factory perspective as it maintains their ongoing sales.
I'm sure a carefull study of the AP catalogue will find you a perfectly acceptable alternative particularly if you want to move away from the drilled version.

So here is what I’ve got.
So the answer is yes grooved discs are available from AP.
They would be 8 grooves on each face, the price would be £225.49+vat+shipping each, delivery time once the order has been received is 7 to 8 weeks (could be a bit less). The kicker would be that a minimum order of 10 pairs (20 discs or 5 car sets) is required. There MAY be also discount available, though we’ll have to see.
For comparison the standard cross drilled ones are £249+vat+shipping each which are either on stock or 2 week lead-time depending who you order them from.
The base part number that I’ve been given is CP3580-1048 & 1049 (the different dash numbers are for Right or Left), I also have drawing so if the person I got it from doesn’t mind I could post that as well. if it would help. We would need to triple check this number before we go any further (my car is not here for me to check).
In the end if there is sufficient interest an order could be made. I’m interested in 2 pairs (4 discs). Anyone else?
I guess the best way is to PM your interest (no promise), possible quantities and we can see if get enough for a “club” order.

Groves dont crack after heavy use. This is not a fault or problem but all drilled discs if used hard will eventually start showing cracks- ask any 911 turbo owner that has driven hard!
For Ultima owners this is not really a big problem unless you use your car on track a lot ot do very high speed braking.

Great we have 8 pairs so we would need 2 more pairs for the mimium (there is no maximum).
Yes it is just the disc/rotor not the including the bell/hat.
We do really need to double check the base part number to make sure we order the correct parts. Would anyone have some new ones lying around to double check the part number?
The non-cross drill discs don't crack and warp like cross drilled ones even with moderate use. They also have more surface area for more braking proformance. Cross drilling is a bit old fashion as most race cars on steel brakes have grooved discs.
