Can you eliminate infamous xi front wheel gap using KW V1s?
Just looking at spring rates the V1 are quite a bit stiffer than stock, but on the softer end for aftermarket options. Coil overs are height adjustable so you can lower them as you want.

It would depend on the shop and if during the install you needed bushings replaced, etc. I don't let anyone work on my cars though so I couldn't really quote.

With that calculation the BC's are closer at 2, and monomax are way off at 0.6 :s

I wonder if you can spec slightly less stiff front springs for bc?

People who have them seem to like them so they must not be too punishing on the street or understeer horribly right?

Still interested if anyone has used the Monomax

I ordered some BC coilovers yesterday from FCP Euro. They have lifetime warranty.
