F6RD Donating Members 249 Member For: 16y 6m 5d Gender: Male Posted 07/09/10 11:01 AM Share Posted 07/09/10 11:01 AM I need to replace my rotors for my 4 pot brembo fronts and was seeing if anyone else had gone for DBA 5000 2 piece rotors.And whats the difference between crossed drilled\slotted and just slotted.Cause on the site they reckon that slotted are more suited to racing over slotted and crossed drilled.I would have thought they other way.The price of DBA is $1100 and brembos about $750. But when replacing DBA's again they are cheaper because you dont have to buy the top hat.Any feed back would be good Cheers. Link to comment Share on other sites More sharing options...

But when replacing DBA's again they are cheaper because you dont have to buy the top hat.Any feed back would be good Cheers.I have 4 pot Brembos at the front of my FGXR6T and am onto a set of slotted DBA5000's. Last set were slotted DBA4000's. They lasted 5 track days and about 60,000kms which I was happy with as the SBS race pads I use at the track are quite abrasive. Standard Brembo pads were used on the street and were fine apart from dust which doesn't worry me.The drilled and slotted rotors are more show than go in my opinion. The slots are not as long or deep as the slotted (only) rotors which help the hot gases escape more effectively under repeated, heavy braking I.e. circuit use.I would only go the 2 piece 5000's if you need to reduce the unsprung weight of the car for track use though. The alloy hub does make a difference (especially when used in combo with lightweight wheels) and ofcourse if you go through rotors as quickly as I do, when you need a new set you only have to replace the rotor itself and not the attached hub like in the 1 piece 4000's. Saves a bit of $$ long term as you mentioned. Link to comment Share on other sites More sharing options...

I'd agree with that.Cheers for the support Worm. Link to comment Share on other sites More sharing options...
BCR01 Member 152 Member For: 14y 6m 21d Posted 08/09/10 02:48 AM Share Posted 08/09/10 02:48 AM I agree with the statment. I have Brembo discs of F1 Cars (prior to carbon fibre rotors) and you can see that the cross drilled holes all have cracks starting in them. This is not a problem becuse they get thrown out (or sold to rave fans for paper weights) after each race. I dont reccomend cross drilled for street or race use. I Like the idea of Dimpled and cross drilled, more for a visual affect. I have not seen any data that says cross drilled is better than slots only. THe other factor is, how many V8 Supercars, still have cross drilled rotors, I may be wrong, but I think it is 0!If it was me I would buy DBA's over Brembos, for a few reasons, one of them is that DBA is an Aussie Company and they have been designed for Aussie Roads!

HIRO F6 Member 1,817 Member For: 16y 1m 18d Gender: Male Location: Brisbane, QLD Posted 08/09/10 03:00 AM Share Posted 08/09/10 03:00 AM Your right BCR. The V8 Supercars used to run a cross drilled rotor and now all use the control slotted rotor. This was done for cost cutting reasons as it became too expensive to throw out a set of rotors after each race. Link to comment Share on other sites More sharing options...

Will be going slotted next time & definitly different pads to the Brembo ones. I can clean the wheels & in 2-3 days they are black again. Link to comment Share on other sites More sharing options...

The Cost for the Brembos are also a lot more than alternatives. Link to comment Share on other sites More sharing options...

You would be surprised what a difference lighter wheels and brake rotors make, and in my opinion defintely worth the money if you demand high perfornamce components.
