For Sale/For Trade gs500 Sonic springs (0.80kg/mm)

[OrTahor]

Hello.
I have for sale (or trade) 0.80kg/mm front fork springs made by Sonic Springs.
I bought the springs from the user slipperymongoose (old WTB thread - http://gstwins.com/gsboard/index.php?topic=63027).

They have served me well. I put about 3000 kms on them, together with slipperymongoose's 9000kms, they've seen about 12,000 kms of use.

I payed 50$ for the springs (and 50$ for the shipping). Am asking the same or best offer.

Am interested in trading these for uprated gsx-f600 springs (0.85kg/mm or 0.90kg/mm) to fit in my new front end If anyone is interested, Ill gladly trade!
