I did about 450 miles over the weekend and my dog has confirmed that the ride is acceptable ( he did mutter something about run flats ) . He wasn't sick .
He says anyone who wants to drive their 335d like it was a proper M car needs to buy one of those and stop moaning .

Woof

You must drive very carefully. That i3 is definitely the car for you.

I take driving carefully as a compliment , thank you .Do you drive otherwise ?

My 335d is lci with adaptive suspension , ironically having searched what to spec on the car and found the op's criticism of standard suspension ...

And the dog with his take on these comments

Why's the dog got a sick bag? But seriously you have the best factory set-up. Your opinion may differ with pre-LCI passive damper car.

A owner of a F31 335d MSport with non-adaptive suspension & 19" wheels, previously owned 535d, X540d. Completed a few thousand miles now. It's a fast , but flawed car. Point a shoot in a straight line, very impressive , grip is amazing, but set it up a few bends and the body control is poor. It appears to me that the car is over sprung , particularly in the rear and under damped both ends. It crashes over pot holes, but can't control the body at high speed. Worst of both worlds. First BMW I've been disappointed with the handling, doesn't deserve an M badge.
I expect it could be a great car with a re-map and chassis sorted, but I wouldn't remap the car without updating the suspension.
There doesn't seem to be many options on the upgrade route:
ASC do springs or coil overs, KW do coil over, and Birds do a B3X fixed rate kit of Billies and matched springs (a lot softer on the rear).
Does anyone have any experience of tuning the chassis on the car please?

Started this post a long time ago. The replies have varied from the ridicules to the sublime. From the original post I was asking for the best way to improve the car. I was expecting useful feedback , practical experience of tried and tested hardware. I am disappointed, I've been criticised on my vehicle handling expectation, vehicle purchase decision, vehicle body type, pet ownership, why I didn't buy an M car, why XDrive , the list goes on.....Like many I can afford only one decent car, which has to tick may boxes, with usage from family holiday, shopping to track days. I've learnt a lot in the last 6 months, and I'm very pleased with car I brought and the final modified spec. I hope other F30XDrive owners get something out of my experience. I prefer technical level discussion with like minded enthusiasts, for that reason I'm out and will 'jog on' or whatever to enthusiasts forum.
