GR-2's are really just a slight step up from stock and can't handle a drop much better either. AGX's are better but u can still blow them too. I have been on H&R springs and AGX's for 5 years (WOW) and the AGX's have headed up good but they are on their way out. Also the stock in the back and lowered up front is very unsafe, i found out the hard way. Hat my 8g dropped like that for about a month when i went through a soft curve and the back end came around and i ended up in a ditch. I was not speeding of driving aggressive, it was because of the different spring rates. So be careful.
