24V & E320 brakes vs. pressed ball joints vs. std. wheels
24V & E320 brakes vs. pressed ball joints vs. std. wheels
This is the E320 brake disc; 294x25mm:

This is the 24V brake disc; 295x22mm:

Despite being smaler, the 24V disc has LESS clearance to the ball joint, due to a higher inset! But; it clears, if just.
Next issue: wheel clearance. The caliper is wider. That's the only issue with stock wheels. You can see where the caliper fouls (don't be fooled, it's MUCH wider, the wheel bolts don't even grip the threads!):

However; with only a 10mm spacer - the stock non-24V 15" wheels fit. Even the steels.

The wheel clearance was tested with the 24V caliper, I don't have a E320 caliper at hand. When it comes to thefour pot calipers it's VERY important to know: the early 320s had the 24V brake setup!! 22mm thick discs. It's only the later E-Class face-lift models which got a slightly different brake. With 25mm discs. Due to the differently sized discs and different offset of the discs, they are NOT interchangeable. But the later E320 294x25mm disc has much better clearance to the std. pressed ball joints!
Usuefull information to add to this thread would be: do std. wheels clear the E320 brake?? With a 10mm spacer?
I guess this is all more orless known, I just though I say it one more time as there seems so much confusion about those two brake setups.

We usually only keep the best wagon steels, the rest goes straight to the scrap skip... But now to the W210 control arms - how'd you fit them!? As far as I remember, the ball joint is in the wheel carrier?
And here's the mising 300x28mm brake disc that does all the magic:

Yes, they do clear it - but the E320/294mm disc has better clearance. So if I was to upgrade to the "smal" 4-pot brake, I'd use the 294mm brake
I myself am going the 300mm route.

I also have got a set of late 320 brakes for my 300D 1985, but it seems like the lower balljoints clearence is different. a early w124 from 80ish has smaller clearence than the later ones.. ? anyone tested this?
