ok so its come time for me too pick and purchase the K-member i want too drop in my baby...lol. and I really think i want too go with sophn since this car will still be driven on the street during the summer. only thing that i cant figure out is the diffrence between there regular K-Member and theres LSX series one.. I will eventually be swapping a LS1 in over the 3.4 i have in there now over the winter and i dont want too have too buy a k-member twice. I just wanted too know if there was any diffrence besides the motor mounts. ohh and just bought my ground control wieght jacks talk about sweet and my 275's still fit up front yay lol.

 

The only difference are the motor mounts. I would contact Spohn and see what he can do for you.
