#14955 Non-OE dimension ball joints
Change 15.8.H.4 as follows to remove the last sentence:
“4. The replacement arms or mounts must attach to the original standard mounting points. All bushings must
meet the requirements of Section 15.8.C. Intermediate mounting points (e.g., shock/spring mounts) may not be
moved or relocated on the arm, except as incidental to the camber adjustment. The knuckle/bearing housing/
spindle assembly cannot be modified or replaced. A non-standard ball joint which is present in a compliant
camber kit replacement control arm is permitted to offset from the standard point the spindle mounting location
from the control arm plane.”
And add the following new subsection 15.8.H.5
“5. Changes in suspension geometry are not allowed except as incidental to the effective arm length change.”
Note: This will provide more clarity in the intention of the camber k
Any of you guys who understand Solo rules can you tell me what this all is referring to?
Give an example?
Thanks!
Is this intended to ban "drop spindles" like LG and others manufacture?

I didn't write it, but that is what it seems to mean, yes. That said asking any autocross what the SEB means because we are autocrossers with SCCA isn't a lot more exacting than asking what a woman why another woman does something because they are both women. Might make sense, might not.

Yeah, I get ya.
Thanks.

Didn't this clarifi-change come as a result of something Zimmer did to his FSP Rabbit? IIRC, he did an alternate arm that changed the front geometry a fair bit (I think to correct for roll center and bumpsteer).

I don't see how that's not clear. removed the last line that allowed offset ball joints, and then added a line to make it even more clear that you can't change suspension geometry except through arm length change.
The line banning drop spindles was there previously and as it is not the last sentence (as specified in the change set description) it thus was not modified and will still be there.
