3 degrees of slop....
Moving the LCA all the way forward and the UCA all the way back has given me a sum total of +3 Caster - There is no more to be had without modifications on my car - yours may be different.
Pics and information available as soon as I can update my website.
I owe you guys and Fran / RCR an apology....
After posting this - I was told by Fran that no one has had any trouble getting more caster than this...
I believe in the RCR product or I would not have bought it...
I went back out into my shop a while back and examined my Caster/Camber gauge...
When I pulled the gauge from it's sock and wiped the vials off of dust I found the gimbal mount for the caster vial is (was) loose and flops..
I mounted it and observed the action of the vial when turning the spindle from right to left, the gimbal would flop exactly 3 degrees..
How can this be?
Since my new Caster Camber gauge is on loan - I took the one from my racecar trailer to use. Evidently the screws securing the gimbal mount had vibrated loose while riding in the trailer - or - while it was on loan to someone at the track.
Suffice it to say - I borrowed my own "New" Longacre Caster Camber gauge back from my neighbor across the alley and re-measured. Camber is still where I thought. Testing the Caster at ride height returned a spectacular +6 Positive caster. Coincidently - this is exactly the figure I was hoping to achieve.
So - I've learned a lesson and will be checking my equipment more thoroughly from here on out - and particularly the equipment that leads a rougher than normal life - in my trailer...
So - Guys , Fran - Please accept my apology...
Fran - Thanks for reaching out to me...
