Hi guys,

I'd really like to upgrade my front rotors to something a little lighter and more track-worthy. Is there a vendor willing to step up and make a replacement? I'd even be happy to be the guinea pig, although I do live in Australia. I tried calling DBA, and they wouldn't have a bar of it. Disappointing, seeing as though they are a good brake rotor company.

Kind Regards
Elie

 

Recently I have been in contact with AP Racing and I can tell you that they have developed a 2 piece disk brake kit with 4pot calipers to fit the JCW stock wheels. These kits were manufactured for the Japanese market due to high demand. The kit has 4pot calipers, aluminium bells, 315x22 rotors with 4 grooves at each face, adaptors, pads, bolts etc.
This kit is not on their site as they have sent the whole production to their agent in Japan and they expect to have the next batch in mid December.

Now I have taken careful measurements of the JCW Brembo brake kit to see if AP's 2 piece disk will fit our JCW setup.

Guess what?

IT DOESN'T...

So, as per a two piece disk for the Brembo setup, sadly it seems that there isn't one. And at Nitrac UK, when I requested one they were concerned about the 22mm thick rotor. They could produce one, but with 26mm or over. That would mean converting pads to fit the thicker rotors and the standard width of the Brembo caliper, which is a little unorthodox but still doable.

If you or anyone has anything new to add to this thread, please do so.

 

I've explored this numerous times at many requests over the years...the issue is not so much that it cannot be done but rather than nobody wants to pay what it costs.

A decent pair of hats and rotors (assuming you'd want something other then the lightest cheap casting available) will run you about $550. And reality is that the benefits are marginal here...they won't really improve braking. Add some ss hoses and better pads...you're spending $750 pretty quickly.

For the final cost here vs a complete front brake kit it just makes more sense (and dollars) to move onto that and get it all in one. For stock brake track day guys the disposable rotor format is also cheaper compared to $125ea replacement 'rings' later.

 

When my new rotors get worn, I'll go for your two-piece rotors Todd. In Aus, replacement JCW rotors are 600+

 

When you're ready let me know. Figure I'm a few weeks out on production to do them.

 

Definitely. No rush, as I bought the rotors not too long ago
