Bigger brake rotors don't affect engine performance?

Bigger (diameter or heavier) rotors will effect the cars overall performance. Putting bigger rotors on is the reverse installing lighter wheels, flywheel or an under-drive pulley. It is also an increase in unsprung weight, which effects handling.
But a change like this will not make a discernible difference on the street - except to those that have the oversensitive but-dyno - but it would show up on the dyno and in lap times (a very small time change) at the track. While it can slow the cars acceleration down, being able to repeated stop from high speed could pay off in the long run. The weight increase is the reason a lot of big brake kits use a two-piece rotor with an aluminum hat. Better stopping without adding weight, win, win.

Just picked up a new set of 2011 calipers, se rotors, apex lines and stoptech pads Just need some decent fluid. I cant wait to get these on and see if they handle an open track session.

The caliper piston is the same size, so the brake fluid isn't gooign to be affected in any way.

UPDATE: abused in the city traffic and almost crashed 4 times (the FDR and Maj Deegan pisses me off sometimes) brakes are wearing evenly and I can use less effort to brake hard lol. No issues at all.

After seeing this,
I went to have a look at my front brakes as well.. Indeed the brake dust cover is a tad larger than the stock rotors =D |
