Non-Sport vs. Sport vs. Eibach Pro-Kit

[Motohip]

Here's a comparison for those wondering what the differences in suspension are. Save yourself the headache and don't install sport suspension from a 135i on a 128i. I did 2 installs in less than a month .

My stock suspension had 95k miles on it. It seems to be lower than everyone elses though. Sport suspension came off a 135i with 25k miles. Car handled so much better with the sport suspension, but it freaking raised the car up. Those measurements are even after the car settled. I couldn't take it anymore, so I bought the Pro-Kit. Handling is even better and the drop is perfect. They are perfectly dampened in my opinion with stock ride quality. That's enough installs for me.

Stock: Front: 13 7/8", Rear: 13 1/2"



Sport: Front: 14 1/4", Rear 14 1/4"



Eibach Pro-Kit: Front: 12 7/8", Rear: 13 3/8"

I see what you mean, could it be the M-sport springs cater for the heavier 135i?

I'm sure they are. BMW calculates spring rates down to the option package, let alone engine.

I wonder if msport 135 fits 328i? Cars weigh about the same and those measurements are slightly lower than my 328i sport spring height. Anyone know the spring rates?
