It wouldn't surprise me if GTM does come out with LTHs, the make alot of other great products for the Z. And ya I do know what I'm talking about, there are plenty of Z's in my area with difference set-ups that I've experienced. Plus I go to all the major Z meets so I've heard alot. Just because I'm not in Cali, making body pieces, or getting the inside scoop on some of the new stuff first doesn't mean I don't know what I'm saying.
