So these are for the S40. The C30 ones are still $250+.

The difference is the ride height drop. C30 drops by 1.7" in the rear.

Has anyone run these on their C30?

Have you gotten these on the car yet? If the rear drop is 0.5” lower than the c30 ones, the ipd poly spring spacer may be worth a buy

I'd just be concerned with the back end being different. While the suspensions are the same, the C30's ass has got to be lighter than the S40's.

That’s a fair point. Might end up with some oversteer. Also, I checked the c30 specific springs and they drop 1.2” in the front 1.7” and in the back, while these drop 1.2” front and back. I’m going to call eibach to get the warm and fuzzies on the differences between the 8432.140’s (this s40 spring) and the 8436.140’s (c30 spring) and report back

Just got off the phone with eibach tech department, and while these springs will fit, body massage is correct in thinking the rear load will affect the suspension. And that effect is a potential 1” LIFT in the rear due to the difference in weight. So these will work in the front but do the opposite of what you want in the rear
