Lowering Springs/Which Camber Bolt Kit to use

I am about to drop my car(05 GT) with a set of Eibachs(Pro Kit). I was wondering where I might find the camber bolts that go along with that kit. Does it have to be an Eibach camber bolt kit or are the kits universal? I talked to a guy down here in Miami at Murray's, and he told me that he would have to order the kit from Steeda for $172.00. I found a kit(part#055-205) on Mossmustang.com by a company called Progress for less than $50.00. Would I be abe to use this kit in conjunction with the Eibach kit?
 
I bought a set of camber bolts from summit racing. 2 bolts (1 for each side) adjust +/- 2 degrees. 2 bolts per side would adjust up to 4 degrees. I believe the bolts were 8.95 a piece plus shipping and handling. They install easily but then you'll still need to take it in to get it aligned.
 
you can use any brand you feel comfortable with. there are many differnt kits to adjust camber, but the bolts are the cheapest.

i used Ingalls bolts from summit racing. part number 35420

Is it better to go with two bolts per side to allow for more adjustabilty? Or do I only really need one per side?
 
I used just one Summit Bolt per side. I eyeballed it to where I thought it was in the center of its adjustment range. Took it to the alignment shop and it was right at the high end of being in spec for camber. They did have to reset to toe-in.
 
I used one per side and turned them all the way for the full 2 degree adjustment. Just by eyeballing it I would think I still have a negative camber. I took mine in yesterday and they couldn't get it on their rack.(sits too low) The only way for them to do it would be if I took off the factory side skirts.
