Suspension?! Just turn up the boost!
how much do the 2010 CJ springs lower the car by ?
None, your front end will actually sit higher, since the 2010 CJ front springs were meant for the heavier 2010 iron block 5.4L engine.

I was just talking to a guy around here at at meet last week who has the CJ springs. The car looks really good/aggressive with that set up and some big tires like he/you have.

Here's a vid of his 10 second nitrous pass. It shows his stance really well though.
That's not the 2010 CJ springs, they sit too low. Those must be the revised 2013 CJ springs.
This is a friends car, he has 2013 CJ springs on his 2011 GT500. Despite the engine being aluminum block, 100 lbs. lighter in the nose than iron, the car is in the weeds.
IMO, I'd much prefer BMR SP009 springs. The link above makes 2013 CJ springs more than BMR.
Besides being very low and looking extremely awesome, how are those springs working out for your friend at the track?
