If you look at a cross section between DBA and RDA, RDA rotors do not have the same heat dissipation as DBA.
Pair that with their sometimes sub par quality, it leads to warp and cracking. Not all of their rotors are like this though, when I was selling them I found there were particular models that were more prevalent to it - typically these were smaller thinner discs like youd see on Japanese/Korean cars or Euros.
I had a horror run with Astra rotors with them and their newer front rotors were actually quite big.
I would also avoid their cross drilled rotors like the plague. They have a nasty habit of cracking, like DBA's did in the early days. Unlike DBA though, RDA has not put in the R&D time to perfect them.
Their upper spec products though, really good. They do the EBC brakes as well as some really good big brake conversion kits.
Hmmm, got me thinking now.
I have a set of the RDA Dimpled rotor ready to go on, look like these, Dimpled Slotted Commodore VT VU VX VY VZ SV6 SV8 SS 97 06 Front Rotor SET RDA40D | eBay . Now you have me doubting them.
Also got a set of their molycarbide rears to go on the back too.
Hmmmm.
