Got them all installed now. Installation went smoothly no problems.
Good thing I replaced the shocks because the ones that were on the car were shot. No rebound at all.
Now pics.
Here are some pics of the springs on the perches for anyone who's interested.
Unfortunately, ride height is essentially unchanged... :/ with blown shock and stock springs the rear (measured at the end of the side-skirt) was about 7 inches. After the springs were on the car sat at 7.5 inches. After settling for 20 mins it was around 7 inches.
If I had spent money on these springs and expected them to lower the car I'd be really upset, but since they were just laying around and free no biggie i guess.
