I am in major need of a camber kit set up for my car. I just purchased it and almost three weeks ago and already had one flat and my air pressure light flash on again today. I have more negative camber than I thought. I am leaning towards buying the Megan Racing front and rear adjustable camber arms and toe bolts. However, I can't find a Megan front set up for my year, but I did find this:

It says it fits 03-09 G35, so I am curious, will that fit my 08 G37S?
Also, what brand is the most popular amongst the kits? I've read up on these forums all day and have heard goods and bads about GodSpeed, Kinetix, Ichiba, and SPC. Im pretty lost on a reasonably priced good quality brand.

 

Welcome to the site!
Out of the brands you listed I'd only recommend SPC, Voodoo has been getting good reviews and SPL are some of the best.

Expect to pay about $500 for a full F&R SPC kit a bit more for the Voodoo sets and over 2x more for the SPL kits.
