I just replaced the RFTs with MPSS. The ride seems softer but the car seems to bounce more...or am I imagining that?

Suspension is stock btw.

The factory suspension is intentionally tuned softer to accomidate the harsher ride of the RFT. When you replace them with non RFT, like MPSS, the side wall flex increases. This makes the whole car fell "loose" or "softer" because everything is soft now. Best way to get rid of that feeling is the M3 RSFB upgrade and Better shocks/struts.

This was also my experience.

1st, make sure the tires are aired up properly. Sometimes shops don't fill them enough.

Otherwise, generally agree with the posts above. Be aware, that once you change one piece, the other flaws in the suspension will become glaring.

And you end up like me replacing everything. Once you start each little weak link becomes a bigger issue, until you replace everything with stiffer peices.
