You say you've tried reds and fancy something different... have you considered Yellows? I'm bedding a set in on my MX5 at the moment and initial impressions are very, very good. I've have also read very positive reviews from others so I'm not the only person with that opinion.
They are cheaper than those pads too IIRC.
I know this isn't a "spec me a pad" thread, but thought I would chime in anyway I won't say anymore on it!
Thanks for the idea. I did consider these when I ordered the reconditioned caliper from EBC. My brother has used them in the past, cold bite is certainly meant to be better than the reds.
The DS2500 are well regarded on S2000s and I like the sound of them as they have a good cold bite. Maybe you are right and I should try the yellows.
