What are you guys trying to gain by adding the '09 front end? I have an '08 XTX, and sold an '08 40th anniv. adn I can say I don't think the $$ spent to do that is worth it at all. There isn't much in the way of strenght adjustments, and the geometry changes can be made much much cheaper with the upper ball joint modification, and skis, shimming, etc..
I'm just curious if you are expecting to see night and day differences? i think you're going to be dissapointed, and the money could be spent making it better elsewhere..
