I'm still around....and busy.

Checked that you got a used NSX-R NA2 suspension in year 2004.
The suspension was installed for test reason in Germany (Nordschleife) at the NSX-R NA2 prototype, but this was the final spec for the production car, so no difference.

I have options for a check and repair, but I will need that damper here.

If there is no chance for a repair, I can offer you my brandnew Bilstein/H&R suspension, which can be adjusted to the simular specs........with height adjustment as additional feature.

This is my actual favourite suspension, which saves the future of my NSX suspension.
Its not the standard way like K&W, its refined with simular spring rates like the R suspension,
even the R dampers was send to Bilstein for a perfect read out of parameters.
