Make sure you know what you're getting yourself into when you order your full coilovers.
For some reason, most manufactures have 12K springs on their coilovers for these cars and honestly, those are drag strip racing stiff springs.
I have no idea why they do that.
On the other hand, if you get a spring / strut combo, you can have a more custom set up to suite your style.
I like to rate spring rates like this:
6K - Street only, very smooth ride when the dampering is set right.
8K - Mostly street, some carving of corners and light track use. Slightly harsher ride
10 - 12K - Drag strip. Very stiff and harsh ride on every day bumpy roads.
That is of course my opinion.
