When launching a high HP turbo or NOS car, which way does the control arm flex?
Is it backwards because the arm wants to move back due to the torque?
Is it forward because when you dump the clutch the tire moves the arm forward?
There was a discussion about this on the list. If you think about it a little bit, the axle and tires start to give torque. The control arm attaches the wheels to the WHOLE CAR and since the tires are trying to move forward and the car is a big damn weight not wanting to move, the control arms would deflect forward since the tires are pulling the control arms forward. They deflect until enough power is transferred to the car and the car moves forward.
That just IMHO opinion

Thanks for your replies! I too thought that the arm deflects backwards, thus I need to adjust the traction/radius arms forward.
Oh yeah, besides the custom intake manifolds, this is my next product I intend to offer to the SR20 community.
Since no one has thrown this into the mix, you might want to check-out N-Tech's control arm brace available from http://www.motivational.net/ It was specifically designed to address these deflection issues.
