Let's get DBA to make the best E30 Brake Discs!

I would LOVE!!! to support my antipodean brethren. I would consider it my Commonwealth duty (as an Englishman) but the US is an odd place for this car stuff and $165+ for rotors would not work for my race car.

Ironically it WOULD work for a track M3 or the blanks on my Wifes car for sure - no doubt, but the $17-$45 for Sino-sourced rotors works against this for racing SE30 - especially as slotted rotors are only marginally beneficial and to be honest, unnecessary for our purposes.

Sorry Mate

A smackdown from halfway around the world? That’s gotta be a SpecE30.com record!!

The rotors sound like tremendous pieces of engineering. Unfortunately, $200 is the price point that most of these guys want to pay for a junkyard engine.:laugh:[/quote]

Piss on you that’s no smackdown . That’s a simple gesture of respect from our Aussie brothers, the same guys that have been at our shoulder in every conflict worth mentioning in the last 100yrs.

Based on my varous brake pad experiments, I figure there’s merit in these high end rotors. IMO:

  1. The rotors would last longer because heat stress is reduced. As Robert mentioned, we don’t abrade away our rotors, it’s the combo of heat stress and mechanical stress that does them in. And if you are running brake ducts they usually crack on the outside because the inside gets some cooling from ducted air that didn’t make it into the rotor’s inlet.

  2. Your pads would last longer. Just like the outside rotor wears faster, the outside pad does too. More cooling equals more life.

  3. You’ll stop faster. We get used to applying the same amount of brake force in a given turn. As our brakes get hot and therefore less efficient, we often don’t adjust by pressing our pedal harder. In the absence of adjusting braking patterns, cooler brakes means shorter stopping distances.

The question remains, are the advantages worth the cost? That’s an individual decision. Folks in the fight for a podium position at Nationals are going to look at a couple hundred bucks for some spiffy rotors differently than somebody (me) who’s objective at CMP this month is not to humiliate himself by running novice lap times again.

I don’t see any way their could be a performance advantage from them. Putting on a new set of cheapo rotors everytime you change pads and bedding them in together will most likely give you the best performance and cost less.
