I unfortunately have apex on it and they are horrible, I like how they have took the 4x4 look away from the car but every other thing about them is terrible
If you do a search for Cooksport / Sportline / Mark Fish springs you'll find some really useful info as it's been covered plenty. If you're still struggling then post up and someone will help out or point you in the right direction.
At the end of the day they are all going to be roughly the same height and stiffness, if you wanted a soft ride you should not have bought a trophy, or you just need to get used to it
Did you get given the oem ones? Try them for a bit, then at least it will give you an idea what the ride is like out of the factory, I am running Mark Fish springs and Koni dampers that I have adjusted harder, and I have solid top mounts and powerflex rear purple damper bushes, I use the car as a daily and do not find it a problem
from what i have seen on here and other forums quite a few people do it, i think they are mad personally and do not know why people go out and buy a T if they want BMW comfort levels, makes no sence
Would you mind putting a couple of pics of how the car sits now with the cooksport fitted? Looking at getting a set next month and would be interested to see how it sits.
