shaking at 130km/h

First step before taking it to any workshop.

Go to a tyre shop and get a wheel balance.
It's not expensive, and it's the most likely cause for vibrations at speed.


If that doesn't help, then it's maybe time to look at the more expensive possibilities.

These cars are quite sensitive to unbalanced wheels and tyres - the earlier the model MX5, the more sensitive. Vibration at speed can be a common complaint, but is most often related to wheel balance. All it can take is a small hit to a wheel or a flat spot on a tyre, and you're done for! It can take much frigging around to sort, requiring patient balancing by a tyre tech who is willing to try and solve the problem. It can be almost impossible with used tyres if they have worn unevenly.

It depends on the wheels too. Cheap blingy rubbish made in the back streets of Bangkok won't do.
