The stock damper is light as may have noticed. I initially wanted to get a Ohlins adjustable but came accross another site where guys had refilled the units with 20 weight oil. They reported some success using this mod on the street and the track. This will give a bit more resistance over the stock fill which I believe is 5wt. So one draw back will be the lack of adjusability but I'll save 300 bucks. I'll give this a try and be the guinee pig.
