I just bought a new pair of S-03's for the rear (too many races )

I am still running the OEM S-02's in the front... there isnt going to be a problem with performance or handling is there? The front tires are almost perfect still... and I didnt need to replace them.

I hope I dont have to return the S-03's to TIRERACK and get S-02's. If TIRERACK would even let me switch back if there was a problem.

Please let me know... I want to make sure my baby is ready to roll as soon as the weather turns around.
