I'd say that the combination of the springs and poly bushes are your problem.

I've rarely heard of anyone saying that KYB's are too harsh, firm maybe, but not harsh.

Your best bet would have been to just replace the struts and springs before doing the bushes, to see if you really needed to replace them or not.

Personally, I've never been a fan of the poly's, but then I'm a bit old fashioned in that sense perhaps.

Polys can actually stiffen up as they age, and the material dries out.

Rubber bushings tend to dry out as well, but will get a bit sloppier, as the material breaks down.

Many people have switched to polys simply because the harder rubber bushing solutions are few and quite expensive, not because they are better.

I'll take the TRD rubber bushings, or Cusco

'hyper rubber' bushings over poly any day.

The stiffness difference is very small

(movement wise), and the rubber bushings will absorb shock significantly better.

From posts I have seen elsewhere, I believe the KYB GR2's and Excel-G's are the same strut.

They are just marketed under different names in the US and in Europe.

I have also seen that they are shortly to all be consolidated under one name

(I forget which one though).

Edit: I forgot to mention that you should give your new struts about 100-200 miles

(200-300 kms) to break in before really judging them, as all struts I have ever used felt especially stiff until broken in a bit.
