   I believe the mod that Johnny does and which I also executed moves the
   balljoint 3/4 of an inch, providing about 7 degrees of caster; eleven
   is probably excessive IMO, especially ona narrow body car. I executed
   on my GT5 to try and reduce the tendency for tramlining of the 275 wide
   tires.
   I'm also intigued why Charles experienced tire rub in the fender upper
   front as the addition of positive caster rotates the wheel rearward
   over the center pivot point.

Dear Boyd,





                 Eleven degrees!   Impressive.   Do be aware of my sad experienc
e with five degrees of positive caster plus stock rolled fender lips plus nine i
nch wide by seventeen inch wheels with 245 mm wide tires----at full lock it tend
s to permit the tire to kiss the front upper outer fender lip.   Following that
is a notable blemish and a trip to the paint and body man for a repair to fix th
e damage and a recontouring of the fender flair to prevent future "kisses".
The advantages of big positive caster still outweigh these minor disadvantages.

I sent my front upper A - arms and had them modified in a manner similar to pat
Micals. I used Johnny woods to do the work. His modification is supposed to obta
in around 11 degrees of caster.
