After searching it seems that these are probably eibach springs (I had already guessed that because summit seems to use alot of edelbrock designs and I believe eibach is through edelbrock)

to the point, is anyone running these springs? No rumors or 'get what you pay for' but is anyone actually have these springs in there car and how do they handle/look?

Don't know for sure about the Summit springs, but I work for a Mustang retail company and we carry Eibach. We also have "our own" brand which is a set of Eibach springs that we sell under our name for a cheaper price (same exact specs). My guess is the Summit ones are actually Eibach ones as well. There is such a huge mark-up on their springs they can afford to have major companies sell them under their own name for a cheaper price.

You can always ask the rep at Summit who they buy from or who the manufacturer is.

I remember reading about them from someone on Camaro Z28, apparently they gave out shortly after installing them. I think you might be hard pressed to find anyone who is actually running them around here though because recently it's blasphemy to run / try anything but one certain brand of spring.

Your butt hurt because people buy/recommend what is proven to work day to day?
Its the same exact reason no one recommends buying an ebay electric supercharger over a real supercharger.

You're an idiot. Comparing different brands of springs that use different rates to fake electric supercharger garbage is the dumbest comparison ever.
