Well I spoke with Eibach's tech dept. today and they say that the springs they have listed for the MS6 were tested with an actual MS6. They said that they are using the ones like the V6 to compensate for the weight. Now if someone has some free time I want them call and see if they were just feeding me BS or if it was true. I know this is a big debate among us for this car and I would really like to get this settled. I also asked if they had any plans on redesigning the spring for the MS6 and they said no. Thanks
