S197 vert cowl shake

I have strange sort of side to side shake over bumps that I think may be a convertible thing. Anyone have experience with this and any possible fixes?

Thanks in advance

Have you invested in a set of good full length subframe connectors?

Odd, cowl shake even in a vert S197 is minimal .

Spend a day driving around on sub par pavement and you will feel it. Its not as noticeable as say a SN95 vert, but its there.
