first off... the perches on the AGX's are welded.... now I am dropped 2-3" on GC's and AGX's and I hate it.... the agx's are longer than stock... so up front, the ride is terrible... it either bottoms out on soft setting, or u set it to stiff and u have a crappy ride... so either way ur gonna feel everybump, but if u set them to stiff at least u aren't hurting the struts. as far as the back.... they are longer as well, it just doesn't make that big of a deal due to the length of travel the rear has. I plan on replacing mine with Tokicko's when I get a chance. Koni's are the best, but I believe u have to have a special GC slevees for them for them, that and they are very costly.
