AGXs are a waste.. Guys blows that out as quicker if not quicker then the gr2s. Plus for the price your going to pay for them... Your better off going the diy.. C/O and have the ability to adjust your height and get it set to where you want it... The information is out there just do some searching.. If you still decide to go the spring well that's something you have to decide it's your car not ours so your opinion should be the only one that matters.
