yesterday at Knockhill I discovered a new problem.
My car vibrates very strongly under full throttle.
The vibration seems to be coming from the rear, as if it was a very out of balance wheel (or both), is stronger the more throttle I give, happens between 55 and 100 MPH (with a peak at 60 and 90) and dissappears when I release he throttle (even if at 60 and at full chat).
Now the car was perfect the last time I drove it, and the only difference is that I had it at the Lotus dealer in Aberdeen for service, where they coincidentally found a broke CV boot and booked the car the following week to change it.
I didn’t drive the car meanwhile, and from my house to the dealer I don’t do 60 or 90. Even less full throttle.
Now, I’m going to call them of course tomorrow, but since I have no idea where can this come from, wanted to check the collective knowledge first.
Obviously they assembled someting wrong, but… what?
Wheel balance is out of the question because on partial throttle or coasting there is no vibration.
What could it be?
