Should we "mod" the suspension

I had a Dinan stage 3 suspension on my E46 M3 and thatw as a significant improvement on the road and track.

The reviews I have read have called the 1M stock suspension perfect for road and track

Should this car's suspension be replaced as new?.. opinions please...

I think that depends on the owner and your intentions? If you plan on tracking the car, the current suspension may not be right for you. If you use it for a DD, you may find the OEM suspension just perfect.
Plus, from the sounds of it, this car may be quite the collector car some day...

Here's a good start for you. "Perfect" for the track is probably not exactly correct, but I think the poster in this other thread is probably pushing it quite a bit harder than most other folks would on a track. Bottom line: if the car is a DD with an occasional track day, it's probably good like it is. If it's your track machine, you'll probably want to upgrade the suspension.

It's perfect on the street but feels too soft for serious track use. I don't want to lose the street ride but plan on suspension that is a good compromise.

I totally agree on a 135i. But the 1M already has the full M3 suspension. I think good dampers and higher spring rates would still be a big benefit. Also, you can lower the car so it just looks better, too. Everyone's different, though. Stock is by no means a "bad" setup

It does have more pitch, dive, and body roll than I expected but it's by no means excessive. To me, the car gets a lot of it's front end grip from the front suspension travel. Initial turn in has so much bite that you begin to think it will not understeer, but it will at a very high limit. The diff works so well that I found I could minimize the understeer with a little abrupt throttle as soon as the front started giving up and the car would turn neutral to oversteer without delay. It really is a very balanced car that acts as if it really likes it's driver.
