Wanted to put some lowering springs or coil overs on this 07, what yyou guys think ?

 

I would go with springs myself. I guess it depends on your budget though. I would do springs because you can get them for a little over $200. Coilovers are nice and have a lot of adjustability for whatever you want but at a cost of $600 and up from there.
I also have an 07 and dropping it an inch or two would look real nice. What size wheels are running? Are they factory or aftermarket?

 

Stock wheels! Looking into getting new rims and tires, not sure though might just get new tires and lower just a little bit

 

I hear you about the keeping stock wheels. I just bought some stock wheels the other day as I am running the steels with hub caps right now and I don't really care for that. I think if you just want to go an inch to an inch and a half lower then lowering springs would do the trick. I've seen some pics of this done with TRD springs and it looks really nice.
