DBA worth it or not?

Anyone who markets slotted rotors wants you to buy them, so of course they will tell you why you should have them.

As MRT say, the slotted rotors scrape off the surface of your brake pads to remove the glazing (as I said in a previous post).

If you are not glazing your pads (and with the size of those rotors and the weight of the car I can't imagine that you are), all you will do is scrape off perfectly good brake material everytime you use your brakes.

Why do race cars have slotted rotors? Because race cars spend 100% of their time racing, are likely to glaze their pads and don't have a problem with replacing brake pads like you and I change underwear.

Yes Peter i understand where you are coming from. But everyone who has tracked the polo on standard rotors and pads has stated that they fade pretty badly. Now i know different pads and fluid help alot. But when you are changing the rotors what else do you use to get rid of the heat and maybe gas. You could just get dimpled i think. Personally i will track mine to see what i think first, but i have been looking along the same lines to replace standard ones.

I agree with Peter here, the vr6 came with slotted rotors as stock

They feel heaps better than drilled. I have seen rotors that have been drilled aftermarket and have hair line fractures showing from them. Slotted get rid of that slice of crap brake pad and do the trick helps on the vr thats for sure

Steve, Peter is saying you dont need slotted rotors. Interesting though that the VR6 came with them. And you will notice i said dimpled not drilled, dimpled dont go all the way through the rotor so the rotot shouldnt crack..

Well, a cheap (free) quick and effective way is to simply remove the backing plates.

[shaneth]

hmmm why were they there in the first place? any pics or DIY As i would be interested to know.

[DubSteve]

True, True on the dimples I think that slotted are fantastic I certainly think that they are worth it.

I know that my vr6 came with it not sure about others though

What do those backing plates do anyway, a cruise through the megalong valley last week and a r32 got a rock stuck in it, made a terrible sound lucky we were able to get it out.

Shaneth, I agree - I'm sure standard brakes would fade with track work, but remember that we are talking about 312mm Audi rotors and calipers here not standard Polo stuff. The only reason you would get slotted rotors is if you are constanly glazing your pads due to the rotors being unbale to dissapate the heat. I'd be going for better pads with the ability to take higher temps before slotted rotors. But again, here we are talking about 312mm rotors and (Iwould imagine) better than standard pads.

Slotted rotors are very, very noisy and destroy your pads very quickly for what would be, in this case, I believe, little or no benefit.

[DubSteve]

I agree slotted are noisy they squeak all the time getting rid of the hot air when breaking.

Interesting to hear opinions guys. Ok i am running textar pads and martini brake fluid.
After 6 hard lasps still had a little fade.
I have a set of ADR aproved braided brake lines to go on so looking at rotors at the same time may aswell go the whole hog. Only looking at slotted not drilled. I have the opinion if i am going to upgrade my brakes i would like to do it proberly and not by half.
Also loooking at a Froedo DS 2500 pad to complete the upgared.
P.S backing plates already gone.
