Vented Brakes…will They Fit...


Recommended Posts

Hello All,


Trying to bring back a car that hasn't run for 15 years and I'm up to going thru the brakes.  The callipers are badly rusted.  Before just replacing them I'm considering going to vented brakes.  I've read in the FAQ that they may not fit some 13" wheels.  Anyone know it they'll fit FPS wheels (13x5.5)?  I'm not quite ready for new wheels yet…(gotta watch that scope creep!)




Second question…in the FAQ there is a statement along the lines if you're going to run 15" wheels you should go the Tii route with the bigger spindle, vs the volvo route, or eat up bearings.  Anyone with the volvo setup really have any bearing problems?


Thanks in advance...

No real reason to go to tii struts on a street car, except maybe slightly reduced maintenance.

As in, repack front hubs every 50k as opposed to 25k....

The volvo calipers can be slotted or redrilled to move them in a bit, which also

helps clearance.

I suspect tim385 is right, but, to be honest, there's probably not a lot of experience on this forum with those particular FPS alloy rims: I've seen photos of them on European '02s, but I've never run into a set in the U.S. Do you know the ET of the rims? If they date to the mid-'70s or later, the ET is likely cast into the rim. Otherwise you'll have to measure the ET.

The early factory alloys ('71-'73), by FPS, were ET26. The late factory alloys ('73-'76), by FPS and Mahle, were ET28. But both are 5x13 rims. The only 5.5x13 FPS rims I've seen mounted on a U.S. '02 are the 5.5x13 "early e21" version of the "late factory alloys." Because these were intended for e21s and not '02s, they are ET18. If your rims are ET18, I would suspect they'd be even more likely to clear the vented disc calipers, as the rim is shifting outward when compared to a stock rim (the stock 5x13 steel rims were ET27 for round taillights and ET29 for square taillights).

Good luck with your project!

First, thanks for everyones response!  I'm going to go ahead with the volvo route.


I just looked at the rims…no ET marking although it maybe hidden under the grime!   Just "FPS", "Made in Italy", "5.5 13, and build year marking with "72".  Tried to measure the ET and it was more in the 25 range than 18. Also the car is a euro model.

    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
