What are your thoughts on grinding down the radius rod where the bushing sits on the rod. Purpose would be to pull hub forward increasing caster. I was planning to grind about 1/4 - 3/8 and using washers to fine tune. This is on a 4th gen prelude.

Thoughts? Concerns? anyone try this, reviews?
How much caster would you say is too much caster? (car is autocrossed and occasional track days)

In the searching I did it looks like it is illegal for many racing classes.
