hey.

they have the same spring rate as the eibach springs. just one more coil. you can safely cut one coil away.

not sure about the amount of lower. i did mine and about 30 mm lower front and rear. looks really good.

you need to half the buffer on the shockers.

as expected the ride is lower and firmer. better handling.

imo. save your coin and cut the springs instead of buying the eibachs. that is my opinion.

a couple of notes:

ensure your springs are seated properly.
ensure you cold gal the end of the spring you cut to ensure that no rust occurs
cut the buffers of your shockers
cut from the top of the spring
use a hand held grinder to cut he springs
have fun with the fronts.
read the maintenaince manual for the fronts.
spare one or two days for the work. the fronts can be hard. but you MUST lower the a-arm to do it.
