I'll be ordering myself a set of level twos soon. I can't personally tell you they work, but I've heard literally nothing but good things about them. Have not once, and I mean once, heard someone say they didn't work.
I'm kind of new to this forum. I am constantly on ls1gto.com. There is a lot of useful info there about preventing wheel hop. I have an m6 so mine is guaranteed a lot more severe as yours. A4's don't suffer from it quite as bad. There are several fixes. Bushings, and g force anti-wheel hop half shafts are the best route imo. http://www.shop.gforce1320.com/product.sc?productId=178&categoryId=5
I have a 2006 ls2 GTO m6. Joined to get some useful information. love working on bikes and cars. I go to cscc and take classes over at bolton field studying to become an a&p mechanic. i work at Ryder and i have a landscaping job for the majority of the year.
