did he give you a print-out of the alignment testing results? it sounds like you need a rear camber kit not a front kit. I did the PDM Racing kit since I only needed a little adjustment. If yours is at -1.3 then you will only need minor adjustment, which you could get from the stock eccentric (sp?) nuts that are already on the rear arms. Provided they have not already been maxed out. There is also a Stillen and SPL kit available. I really can't see why you are ripping up your tires so bad if it is at -1.3
