I ve been looking for some control arms and came across some good prices for X2C, Ford Racing, and Granatelli Motorsports. I can get upper and lower control arms from X2c and Granatelli for less than 150 new( for upper and lower together). Are those good brands and will I see a big difference between those and my stock ones. I am trying to get some good products for a great price, I don't need the best of the best , but I don't want to get some cheap quality products either. What do you guys think. How much improvement can I expect in the 1/4 mile with theses. Are adjustables worth it?
