TRD Springs

[Chodey]

I'm looking to buy the TRD lowering springs for my car and wanted to know if anyone thought it is enough/not enough of a drop for the 18's that come optional with the tC. I want to close the gap and want to know based on past experience, if you think it's enough with the TRD, or should I go lower with other aftermarker springs. Also, is the camber adjust kit necessary if going with the TRD? Necessary with going lower than that?

Last, I'm interested in re-doing my exhaust from the headers all the way back... Is there any way to make it street legal or is replacing the whole system "off-road only" since I'm removing the cat-converter to install the header...
