When getting the H&R springs, I assume you then only need the MM spacers for the rear to equal out the stance front and back
Than, is there anything else needed when installing the springs? I assume the stock shocks will work. Until I can get better?
Your assumed reasoning behind the need for the MM spacers is incorrect. Without explaining why, I'm just going to tell you that you need them and you should install them. There are dozens of other threads on here that explain their purpose.
Stock shocks are fine, unless they're worn the hell out.
Badge overlays are from 8th Day Creations. Search them on this forum and you shall find.
As for measurements of the rear spring spacer, all you need to do is a) read Ed's post that he linked above, and b) use the lower spring isolator that sits on this spacer as a stencil to trace the 2 circles onto the 60 durometer rubber that you'll buy after you read Ed's thread.
Wes, what size tires are you running on the back? Any rubbing?
19x10 with 275/35-19 tires. And yes. lol it's all straightened out now tho. If you want more info, search threads started by me. There are 3 or 4 separate threads that all have to do with different fitment issues I was having. If they're not on this forum, they're over at ls1 tech.
