just a reader

browsing thru autocarparts.com, i see sum springs that i didnt notice before. For example the B+G springs(1.6\1.6), tananbe sustec nf210 springs(1.5\1.0), and the tein springs - luxury master high tech spring (1.5\1.0) <= just a rename?) i was wondering how these springs ride in terms of smoothness compared to comptech and h&r. Are the tein springs just a rename of their old one becuz i dont recall seeing the luxury master part of the name or are they different from before? please comment on these springs
