Curious as to know who if anyone is running 320i ATE calipers on their otherwise stock
brake system, and their impressions... Thanks |

Eric Shea is cringing right now I can feel it...
I did the 320i "upgrade" years ago when I regularly auto-x'd my car--19mm master, stock rears, for street they seemed to bite a bit better...however...at auto-x it could get real scary real fast. The brake bias is all off when using stock rears, so the front end tends to over brake and the rear end wants to come around on you...sometimes that can be good (auto-x) and sometimes not good at all and downright scary. The other big drawback is that you've now introduced larger pads to the same rotors which cant shed the heat very well so under heavy use you have a pretty good chance of boiling your brake fluid and loosing your brakes all together (me @ my 1st sudo-time-trail event, VERY SCARY). Proportioning valve wont help in this scenario--only way to bias out the back end properly is to do /6 rears or PMB's alloy /6 calipers...and quite frankly if you're going to do that then skip the 320's and do something that makes more sense. If you're going to cheap out, dont do it on your brakes, your life may depend on them. |

Sounds like what makes most sense is to get your stock system in order with good pads. Not sure what "makes sense" if you are planning on upgrading to a larger type IV motor (for me a 2270) in the future. If I am just changing the motor out (all other stays the same....wheels, suspension, etc...) and not adding in any more weight to the car, then what makes sense?
