Let me put it this way, Im keeping the damper cuz I purchased separately R6 top mount brackets, so I dont need these anymore. The R6 brackets ran me $175(I cldnt find anyone in the US who had them in stock so they were shipped from the UK). They're less than a yr old, in excellant condition and have been polished.
Im thinking arnd $130 wld be fair.
These mounts are made by ProMach Engineering and they're less than a yr old. I used them for even less than that cuz I traded my R1 midsummer last yr. Plus they've been polished. Ive seen these units range from $375-500+. A damper can be bought NEW for arnd $200. If you really want these mounts shoot me an email w/ a more reasonable price. I cant take that much of a beating nor am I in a great hurry to sell.
