So that makes it sound to me that by simply moving to a slightly larger rotor, I'm not gaining anything.
Trust me, if I can upgrade the front brakes and not spend $1,800 by going to a big brake kit, I'm all for it! |
The calipers on the E36 325/328 are the same on the calipers on the E46 325/328 so there is no upgrade to the caliper itself. That does not mean the 300mm upgrade is not an upgrade... in the most basic terms BMW would not have bothered if it was not an improvement. To be a little more technical you are increasing the size of the friction surface, this allows for better cooling which limits brake fade.
That said, the 300mm brake upgrade is the cheapest possible upgrade you can do for your 286mm brakes so you will not find much difference, especially in daily driving.
I have been through 3 brake upgrades on my E46 wagon and each one cost more than the last but each one worked far better than the last. I'm currently running
a Porsche/Brembo set up and it is amazing. I will be running the same set up on my S50ti.
