I believe 5 pounds is the min. you can run because to my knowledge thats the lowest they are available with. I have never driven a Roe car but from what I hear.....you will surely notice the difference, mainly in low end power. Since you have a 02 (cast pistons), 5lbs is probably all you want to run. You will need good tires like some PS2s to hook up all that power. Also, I assume who ever is installing this will tune it with a VEC 3 or SCT flash that now comes with the Roe. Just be careful as that is alot of power down low. I am sure someone will chime in with "you should do a paxton". But since money is not free and paxton does require more tuning, I would say stick with the Roe because both will give you same power outputs with keeping the bottom end stock (paxton may give you more peak).
Should put you around 550-575rwhp. Talk with RTTTT (Roe with mods putting out 720rwhp) or bottlefed as they both have Roe and like them. They could tell you have daily life with one is.
