Vorshlag's prototype F22 camber plate - ready for testing
A little sneak preview for you guys on the new Vorshlag Camber Plates for your F2x F3x and F8x.
The tricky part was keeping the stack-up height of the camber plate + perch + radial bearing at the stock height, so the car isn't raised or lowered. Vorhlag never made a camber plate + perch this short, but the new BMW top mounts are all going to this super short stack. The new assembly uses a unique radial bearing and assembly procedure that lowers the stack up height of our assembly by nearly 40%. Very exciting - nobody else is doing this design as short or with a proper steel, sealed radial bearing for the spring perch. Other designs we've seen use a plastic radial bearing which has a very short lifespan. The spherical is in the upper bearing holder and allows the shaft to pivot relative to the plate. The spring pivots against the perch, just like the OEM top mount design BMW uses now. The large diameter billet upper spring perch fits the stock spring and also allows for re-using the factory rubber isolator above the spring. Vorshlag will be installing these on a new M235i next week and then give him a few weeks of street and track driving before we finalize the designs and make a production run of CNC parts. Luckily there's no laser cut or other outside pieces they need, so they can machine this 100% in-house - no delays. |

I wish I could've done testing with them :/
I was actually waiting for Vorshlag to come out with camber plates for the f22

No, the spring does not articulate in this model. When we convert them for smaller diameter 60mm or 2.25" springs it will, but with the OEM spring it does not. This is acceptable with the larger diameter springs. And yes, it is just like the stock perch. Any "articulation" you see in the stock perch is because the parts are rocking on each other or the stock bearing is coming apart. When loaded there is no spring articulation.

And this style perch design is being used by other manufacturers. Ford and GM are using it on some of their new cars including the Mustang, Camaro and some Cadillacs. I'm sure there are some grocery getters using it also, but I'm mainly interested in the models that are likely to see some track time.

Is it possible, (maybe not on the stock springs looking at the photos) to adjust slots 45 degrees to add caster as you add camber, maybe a second set of mount holes, or reorientation of the cad file prior to making the g code?

The dual ball-joint cars do not require any additional caster. Don't be sucked into thinking that what was good for previous designs is correct for the current design. The E36 is dying for more caster, and the E46 is only a touch better than the E36. But the E9x and more recent models have been great and don't need any more. To elaborate on it a little further, we can't accomplish what you are asking for with another set of bolts around the perimeter. There is also an M10 stud inside the perimeter that attaches to the firewall brace. Reclocking the plate would move that stud away from the brace. We could add another hole for that stud, but it would be right where the upper bearing holder wants to travel. So it would be very difficult to do what you are asking.

And we see more and more 1, 2, and 3 series guys that are thinking about tracking, or are committed to tracking their cars.
And the lateral play in the OEM bearing, it's because it's a pretty poor excuse for a bearing. BMW relies on an extra flap of rubber in the strut boot to keep grit out of it. We've seen this bearing, and it's predecessors back to the E46 M3, fail in their stock applications.

I would disagree, steering feel is much improved with 2 additional degrees of castor, esp. on square setup on the m235i, but that would be subjective. Yes you loose camber, but I can still get 3.7 neg degrees of camber with the extra castor, which is plenty for a dual use car. That is on the kmacks, which are a very very delicate design, would not mind switching to take out some of the camber when not on track, but not at the expense of loosing my added castor adjustment. Voshtag, whip me up a custom set!

Likely the same reason none M differentials all have the ring gear welded to the open diff now. One bead of weld is cheaper than 12 high grade bolts and take less time to drill and tap the 12 holes in the ring gear! lol |
