For what it's worth I've been riding on Tein Stech springs on factory struts for about 8 years. It gives I think a 1.9 up front and 1.7 in the rear. The ride quality isn't bad. I still am fairly impressed. With this setup you shouldn't need any added camber products. You can get away adjusting the rear camber with some longer bolts and some washers.
Everyone needs to start some where. I've had no desire to change due to the road conditions here.
