DBA 4000/5000 series brake rotors

[Reedy]

So my brakes are shot. Trackwork is producing too much heat and I have cracked my brake pads as a result. Looks like i've outgrown the A1RM, or at least erred in getting better pads without upgrading the rotors to match. Lesson learned there.

I'll shoot an email off to GSL Rallysport today to see what their prices are but for the sake of public knowlege, who can tell me the difference between the DBA4000's and 5000's? Performance/Cost wise? Tunehouse are recommending that I get the 4000's but if the 5000's are better and don't cost too much more then I might go for them.

Does anyone have any other recommended online retailers other than GSL? I want to shop around a bit.

There isnt a 5000 series made for the MPS mate.

The 4000 should be a good investement for track work though.

Are the gen1 rotors same as gen2?

Brakes are the same between models Luke.

i thought it wasnt possible to cook the A1RMs haha !

mine are just about stuffed aswell only this time i have replace the rotors and pads... ill be going down the DBA4000 Route aswell, its a real pity that DBA wont make a 2piece rotor for MPS as i would be one of the first to purchase as would many here.

sell the pads and get something better suited.

Quote from GSL is $198 each for fronts and $165 for rear Slotted DBA 4000's (DBA42962S/DBA42957S). Unfortunately not included in the sale... spewing.

I asked for a quote on the next step up from the A1RM's for the pads, Project Mu Club Racer: $350 for fronts, $325 for rears. Cost a lot more than the QFM's but they apparently last longer. In my case a lot longer, given that my A1RM's are dead despite still having 80% of their material remaining.

I have been hearing some mixed reviews of DBA rotors of late, cracking seems to be a bit of an issue.

[Reedy]

That depends a lot on what brake pads you use. Cross drilled rotors tend to crack a lot more as well but seeing blokes crack rotors at the track, they are all the ones that run super agressive pads and have glowing discs after 2 laps.

I'd get the DBA4000 over those RDA ones. The RDA are equivalent to the street series of the DBA. The 4000series have a higher carbon content from memory. T3_web

the new slot design look agressive I will take a photo of them with my new wheels

Im using the 4000series clubspec with Remsa pads. The initial bite isn't as good as stock, not too sure if its due to the pads and/or due to the harder steel of the rotors. unfortunately i can't test the limit of the brakes as the fluid is boiling. need to get it changed ...
