I have made them out of mirror finished stainless steel they bolt right to factory mounting locations and drop temps well to say the least ,...it is rare to hear my fan run much at all with them installed.. I have tried these on several friends bikes and they are pleased as well... it is mounted lower than the res. bottle so no relocating or in the way b.s. to deal with... the edges are finished with a black plastic edge to protect you or items from being sliced!! They look factory and the mirror is wild,... the rear of it is satin finish.. I think it would be overpowering with miror front and back. I will selling these on ebay starting next week I know they are not as lite as allunium but they will with stand one hell of a beating and sure turn heads with low to no maintainance... I will due for $25 a pair plus shipping... I have a perfect ebay rating and own a heating and air conditioning co on the east coast.. my co is very much hands on with all aspects of metal products.. have no fear of quality.. Please email me for questions or wants I will have pics soon.. Tom [email protected]
