I can't find the spring rate on Eibachs Pro-Kit.
Megan I found here and it's 335 F / 250 R. Which of these springs will hold the MS6 weight better at the rear?

------------------------------
Info from KevinK2:

Sportline .. F and R Progressive = Dual rate
Front = 245/342
Rear = 131/239

ProKit .. Front Linear, Rear Progressive
Front = 199 (sounds low)
Rear = 108/171 [ wagon rear is linear, 228 lb/in ]

--------------------------------

The prokit is a HUGE amount softer than the Megan springs.

That's huge!!! Megan is also linear, this will hold the MS6 better.

correct. Linear is MUCH better, especially on a heavy car like the ms6.
