Installed the sportlines and the rear is just too low to fit the 305/35/20's, if you have a set of rear lowering springs, i.e Prokit, FRPP, Steeda, Roush etc, that does not lower the back as much as the sportlines let me know please.
I would rather do a trade, I can understand where you might not want to split up a full set. I have them on the rear of my car right now but I changed out the front to coilovers so thats why I was looking to see if you would do a trade.
