Wondering if anyone else is having this issue..
-car vibrates through the steering wheel above 70mph on certain road surfaces/gradients but then not at other times at similar speeds / round bends and such the issue clears and if travelling above said speeds it seems fine..
Things that have been checked / replaced
Suspension was a brand new ST X coilover kit
Had Brand new wheels / tyres balancing rechecked
New discs and pads all round
Alignment checked / tyres wearing evenly
Everything was checked underneath but that was on an MOT style ramp so car on its own weight may need to try with the weight off the wheels / suspension? .. only other thing I can think of is prop shaft / drive shafts but all seem good and tight.. don’t want to replace things for the sake of it and not cure the issue
If anyone has had a similar issue and cured it I would be thrilled to hear the remedy!
