John, the 245's are a bit on the wide side for the fronts of the Z3. The 730's are nice as far as the noise is concerned, but the rain and dry a bit less than the S-02's. If you are not planning on being really agressive the 730 will befine, but the S-02 is still way nicer.....much more $$$ too though. Aaron 800.428.8355 x395
