320i Front Brakes


Recommended Posts

I have the 320i disc and Girling calipers to upgrade (actually any brakes would be an improvement but that...) the front brakes. I have read that welding over the mounting holes on the calipers and re-drilling them in-board will give a bit more clamping surface on the disc and more clearance for 13" wheels. It would pick up about 1/8" extra surface on the pads which doesn't sound like much but it probably adds about 15% increase clamping area if I did the math correctly.

Anybody with this combo bothered to do this? NAy recommendations advice on the welding. My only concern is what the heat from welding will do to my nice new caliper pistons I just had pressed.

i believe ireland engineering does this with all of their calipers. they would probably tell you the best way to go about it or do it for you.

Y'all hate this, but...

I just take a die grinder, ovalize the holes a bit,

and slide the calipers in that 3/16" that they need.

So far nothing's failed- and I track the car regularly...

It actually helps a lot with pad binding and cold lockup...

As an interesting follow up to my question, the local machine shop I took this question to said they are prohibited by law (it's Canada....) to making any alterations to a fabrication related to brakes, steering or suspension. Something about altering safety related items that are certified for use on public roadways.

That doesn't mean I can't do it myself or buy modified components (like Irelands calipers) and install them but no shop will touch it. To that end, he can produce machine plugs for me to press in and then find a drill press and rebore the holes with the offset.

Or not.

If we learn from our mistakes does that mean I have to make them all?

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
