Are you meaning the holes on the shock tower???
If found the hole position on the tower to be more about intial turn in grip. If you straighten up (go further out in the holes) your shocks, you loose initial grip on that end of the car. If u use the outer holes on the rear, you should fine you have less rear end traction as u enter the corner. I usually used the middle holes on the rear, and on the front, i adjust to give the right amount of turn in. I had my front shocks on the centre hole, and on turnin, some corners it was great, and other it seemed to have oversteer, so i went out one hole and the car worked awesome.
if you werent talking about the shock tower, then let me know lol
