I have a 2006 RX8 PZ & the brakes appear to have warped. It's coming up to service time so I'm looking to replace them with upgraded disks & pads. Does anyone have experience of doing this? What would be a good setup to go for that isn't too expensive compared with an OE setup? Unfortunately I can't afford a full disk/pad & calliper upgrade, this will have to wait.*

 

If your willing to look to getting parts from the States, Rotorpros has some nice brake rotors for a reasonable price. http://www.rotorpros.net/. We also have a nice selection of vendors, that support the site, that you can find something appropriate from.
If you want to stay in the UK and Europe, we should move this to the regional forums where owners from there can answer your question.

 

They look good and had a speedy reply with a quote. $600 for disks, pads and braided lines allround delivered (minus import duty) seems quite good too. Has anyone else had experience of EBC, Racing Beat or Racing Brakes disks?

Cheers.

 

I have EBC Red pads on my car presently. I think EBC Yellow's would be better for aggressive drivers that want to do an occasional track day.
Racing Beat is one of the original US suppliers of aftermarket parts for rotary engine cars. They have raced and set land speed records. They are reliable. Their offering for the RX-8 seems mild to me. Just a little upgrade over the original parts.
I have no experience with Racing Brake. But, I believe them to be a quality product.
