Looks like 2.5" the whole way. No necking down that I can see. It was a good bit lighter and sounded pretty good on my car. Also much cheaper than the others.
I still have my Eibach/SPC adjustable aluminum control arms and a literally plugged in twice tuner that has Bama tunes on it. Both were in car for 2000 miles.
Wow. I bought through a master distributor at their cost. I'll adjust them down. I paid more than I was asking. They were higher than that on Amazon when I looked too. I'll get some pics. Not trying to gig people, but make good deals on parts that literally have 2000 miles max on them...
Really like to keep them together. By the time I pay shipping, I'm got getting much for them. PM me an offer. You could sell the rear and get some good cash back.
Side note: Intake and shift knob sold.
