I am running stock 17 inch wheels with the stock beefy tires and I find the ride uncomfortable in the city. On florida's highways it would be a dream.

I had a 545i with sport suspension and an old RX7 turbo with sport suspension and both were almost like luxury cars compared to the M030.

I know there is a significant difference between the M030 and not-m030 since I can see other Porsches in the city bobbing up and down over the bumps, whereas I go over them like a 2 by 4 on rails.

Also, someone else posted that the M030 made their front end "busy, bobbing up and down on each side independetly". This is the opposite of what a stiff suspension should do, and s the opposite of what I feel with the m030. Strong swar bars should link both wheels such that they operate less indepently of each other. To that poster, I would check to see your swar bar links are in tact. Anyway my experience is that the front end is absolutely rigid and just bangs into anything the road throws at it lol. One other thing i notice is that if there are wheel depressions running paralell with the road, or if the road is declined to one side, the car will pull significantly in that direction. Maybe this normal for Porsches, but the only other car I have experienced it to this degree is my 745Li with 22" rims. However, if this can also be associated with the m030, it is another point against switching suspensions.
