Can the front rotors be upgraded. With out upgrading the rear rotors. Doesn't that provided understeer.

Under certain driving circumstances better gripping front brakes can cause brake enduced understeer.

Under most performance driving circumstances you are supposed to brake in a straight line so it would not cause understeer, but it could cause your front brakes to lock up quicker than with stock brakes.

I don't see a problem with upgrading just the front brakes on an FC. On almost every FC I have raced the rear brakes locked up before the fronts anyway. And some popular brake upgrades only increase the braking power by very little but they increase the heat disipation a tremendious amount causing your brakes to last longer during a track session (before fade occurs, not necessarly making the life of the pad last longer).

At least our cars have rear disk brakes. Just the other day I noticed a Civic next to me at a stop light. It had HUGE cross drilled, slotted front brakes with some expensive looking caliper (visible throught the oversized wheels). And it looked like he had spent around $4.00 on high temp paint to paint his rear brake drums the same color as his calipers up front. If there was that big of a difference in brake power difference front vs. rear then there might be concern about dangerious brake enduced understeer.
