How to loosen supsension bolts?

[ben]

I finally got them off. Soaked them in wd 40 for like a hour. Then got a piece of pipe to get leverage . And they came off.. Pretty damm hard though. Now the dam tiny bolts on the air dam are also super tight... Ill try with wd 40 if not im ripping off the air dam and buying another one later.. I just need to get the engine out already
