Since the BC Racing BR coil over cartridges/ inserts have pretty much the same dimensions across lexus/totyota model family (GS300,SC300,Supra,LS400, ES300) I thought to post this for those that may be interested (DIY'ers). As long as the BC racing cartridge's piston is 46mm in diameter the same can apply.

Cool.. if you have any questions, please feel free to post there. My hopes are for everyone to realize how easy it can be to revalve their shocks/coilovers with quality parts.

I have finished the passenger side and had it dynoed, but I think a mistake may have been made in prepping the dyno. The data for that shock dyno does not add up. I will have it performed again just to make sure and plan to post that result also.
