TRD shocks and springs

[NoHachi]

600 for new bilsteins, cut, modified and revalved is cheap. Lots of labour involved.
If you want to get serious, try and fit some 36mm options. There are a couple of insterts that don't fit by a mm or so. So use a honer on the housing and shave down the shocks themselves.
The 36mm have a bigger piston and a lot more revalving options. Its a lot easier to get a more digressive valving with them. They will also last longer and work better.
If they are doing the revalve anyway, try and have them leave the bilstein shrader valve in (modify the strut to suit). You can then add an external canister from a motorcycle and get low and high speed bump adjustment. Bilstein also do a rebound adjustable pistonshaft, but its mucho dollars.
