I second the Rod and Custom route. Not a terrible installation, does require a lot of welding though.
"Supposedly" better handling. I say supposedly since I haven't been able to test mine yet. But coil over suspension is better.
You lose the shock towers with this kit so you can fit probably any engine you can think of under the hood.
The kit comes with a Wilwood disc brake setup with ability to upgrade. I upgraded to 12" slotted rotors with 4 pistons calipers, and boy is it sexy to look at. Also comes with brake hoses and everything you need to hook up your steering components.
It's definitely not bolt on, so you will need to know how to use a plasma/cutting wheel and know how to weld. But it's not too terrible.
Can't say anything about the other option, but I know you'd be happy with the RC kit.
