that thing is gonna rip with a 80lb girl on it. same with your gf on it. this is what i would recomend, and i know that people are gonna be like thoes are not good.
buy 2 standard diamond j kits +4 or +6" whatever you want. they will run you about $400 shipped total for both.
next go on ebay and find some stud type wheel spacers. about $25.00 each shipped, so $50 total.
the 03 you will need ling brake lines @ about $60.00 shipped off ebay for some nice ASR ones.
find some banshee shocks for both, and a 400 ex rear shock for both. prices vary.i would say about $100.00 in shocks each.
Total $710.00
NOW...
if you have alot of cash to spend, get some extended a-arms like some +2+1 or some +3+1. gonna cost about $400.00 each brand new on ebay.
still need the brake lines.
g-force axle adjustable width from +2 to +6" about $180.00 shipped each on ebay.
you can use the banshee fron shocks, and the 400ex rear.
Total about $1400.00
or you could do spacer all around (not recomended at all) for like $100 or a little more total for both blasters.
