Neuspeed springs vary on their drop. personally IMO i hate neuspeed. They are meant for those german cars and they wanted to get into the import scene(honda/acura) and try to make themselves popular. Anyways.....You will need a camber kit only if you drop it more than 1.8" and you can make one for the back with washers if you dont want to spend the money for a rear one. And as for the tie bar it helps strengthen out the chassis for better handling.
