Lowering blocks are a pain and sacrifice handling. Get a reset leaf springs and coil overs for the front. I'd recommend Shockworks coil over system, as they have been designed for the FG cars. As for power and control, it depends what your goals are? When I was running the ute daily with a 460rwkw tune it handle fine with standard suspension. A little boaty in the hills but still nothing as bad as people claim. I've been in a ute where a mates just slammed it with kings and blocks.. and my god, it's terrible! couldn't stand how awful it handled. But then again, it's up to the individual!
