[Tigers] Tiger Handling

[CoolVT at aol.com]

I've made some changes over the past few years and  haven't been satisfied 
with the handling.  The 2 things that seem different  are:
Pretty bad understeer on curves at 40  mph+
Car's tendency to want to follow ruts in the road. 
It seems that the 2 problems are  contradictory.
 
The things that I've changed from stock  are:
MG Midget steering rack
Wheels that were high profile 185 x 13 are now 195 x  50 x16 (front) and 
205 x 50 x16 (rear).
Thicker sway bar on front (I think it's  7/8's")
1/2" thick shims above the front springs (to raise the  front a  little
Softened the front shock adjustment because I thought  it would be too hard 
with low profile tires.
Done an allignment and that seems  good.
 
Any suggestions?
