Hello to my fellow camaro owners. I have a few questions that hopefully you all will be able to help me with. I just finished buiding up my 2010 L99 converted to an LS3 with a supercharger running 9lbs of boost with the Ted Jannetty rough idle cam. I recently lowered the car 3/4 of an inch all the way around and used Pedders suspension and also bought a bunch of rear components as well to support all of this horsepower. G-force axles,3200 stall, adjustable lower control arms by BMR and 373 gears in the back. I'm pretty sure I already know the answer to this but wanted to put it out there to my fellow camaro owners. Of course I had to have a 4 wheel alignment with all of the new suspension parts. Now onto the issue I am experiencing, under heavy load the back end is moving around pretty bad and is hard to control. Lots of input needed while at 1/2 to full throttle and the car is almost undriveable. I had the folks that aligned the rear end use the Pedders agressive street settings while aligning my car. It feels like the tow is out on the car which is causing my issue under heavy throttle. The car drives fine when not under a heavy load. The car still has the stock cradle bushings and I do intend on replacing here soon with upgraded bushings. I think that the guys who aligned the car didnt know what they were doing because they wouldnt even give me a print out of the results. Has anyone else experienced what I have described above. The car drove fine before I added all the suspension parts and had the car aligned so I'm leaning heavily on the rear tow or camber being out of spec. Thanks for any help or suggestions

Honestly first thing I would do is add Solid cradle bushings before having car re aligned. Test it then and you should notice a drastic improvement. Then decide if you want to have them realign it or if you want to find a different shop. Did the Pedders come with specs for alignment? While lowering cradle for install I would do the UCA Bushing if you haven't already. The cradle bushing install is very easy with the right tools.
