If I were you, I would just order l76 (G8 GT) springs from GM. The last time I did, they were less than $3 a piece.
lol that's metro Detroit for ya I normally see an average of 3 by accident probably more of I had them print out a list but are those L76 springs too stiff? just asking because I've heard the 1.95s break easier because they are aluminum. also will the #90s be safe?
