Its also interesting to note the angle of the upper A-arm when that occurs. extreme levels of camber gain at full rear compression on these cars.

Me too

 

I notched the UCA on my car:

What in the flying **** is that? Why would you do this?

 

I really hope that's a joke of what you did to an already bent UCA...

 

Some people will plunge a 4.5" angle grinder into anything these days...

 

I plunged something 4.5 inches long into your mom last night.

 

Faeflora style ftw

 

I think he did that because of SCCA Solo rules which prohibit you from touching the body of the car for clearance yet allow mod/replacement of a (upper or lower) control arm. Not defending the action, just providing a possible answer.

 

Is a control arm allowed to clearance the body? Solution: Embiggen the contact area of a spare control arm with a steel plate and jump some train tracks.

 

Well yes, rubbing and self clearancing? is allowed. Also, you are allowed to clearance towards the outside of the track (rotor to wheel mounting surface) but this is inside of that. Solo rules are "WTF?" sometimes.

In any case, OP has an easy solution for his racing habits: BFH.

 

Can you make a control arm with a die grinder attached to the top of it?
