<VV> Axle Jacking

[Smitty]

Smitty Says;   I missed making a big point on axle jacking and rebound straps.  Yes the axle drop angle on a 60-63 Corvair even with the proper shock installed is suficient to allow axle jacking.  I have experienced that.  Ask Bill Hubbell about it.  He has a story to tell about it.  This tendancy is reduced by the transverse spring when the control arm drops down to it.  The rebound straps available were made to limit axle drop to even less than the shock would allow.
More from experience;  Think on this.  You put rebound straps on the car and you go out to the autocross.  You are really "getting it" with your new MIchlin tires on and into a hard turn.  The outside wheel compresses. the body rolls, and all at once it jerks the inside wheel off the ground.  BTDT and I took the straps back off.  The first rule of inertia applies to suspensions as though it was writen for it.  For everything you do to improve it there is an equal and opposite reaction.
