If it shakes at 90km/h then there is something wrong with your tires or rims. Have you tried doing off-wheel balance at a few shops just to make sure it is not due to poor calibrated machines at the shop you went to? Off-wheel balance should be good enough for 90km/h. However on-wheel balance will likely solve it for you but that is more like masking a problem.

Previously I had the same issue and that was due to poor quality of my replica rims where each spoke's weight was very different making it difficult to balance it and only on-wheel balancing can help. I changed to original rims not long later and never needed on-wheel balancing anymore.

P/S: It could be some other wear and tear part as well if your car have clocked a high mileage.

old klang road Michelin shop. The sifu there quite good in balancing and alignment job. For on wheel balancing, have to specifically ask the boss, the machine is hiding behind somewhere

no prob pls report back here if your issue is resolved....it looks quite fun sitting on that machine when they are doing on wheel balancing lel...oh dont stand too near too...be prepared for stones flying at you...i kena before cuz bodo
