The last few weeks my 2.2 has been doing something odd on motorways and dual carriageways. ie at speed, 60+.
It's like a big gust of wind catches it from time to time. Just for a split second But it's always been calm when it happens. The car doesn't wander off and I don't need to adjust the steering.
Iv'e never had handling issues before with any of the Z3s I've driven. In fact if I'm honest I'm still not even sure what tramlining is or if this is what I'm experiencing.
This car has all new front end suspension arms, links, bushes and mounts. Though the struts/shocks were not replaced. Thinking about it, it possibly started happening when I put the 18" wheels on.
Any ideas what it is or what might solve it while we're having a handling discussion?
