hey does anyone out there know what a good spring rate grams/millimetter of compression for me 170 lbs i have seen .08-.10 grams per mm hit me back if you know what is the best and possibly a good company too...

 

I bought some Race Tech springs shortly after buying my bike. I think I settled on .85kg and I'm about 185. If you go to http://www.racetech.com/evalving/menu/searchstreet.asp they've got all the information you'll need to get the right spring rates for you and your riding style.

 

hey man thanks that helped out alot how stiff are your .85 compared to stock would u recomend a stiffer spring if i like to ride agressivly

 

I can't really compare them to stock springs, at least reliably, because the fork seals were starting to go when I bought my bike. The front end was really spongy until I replaced the seals and springs. I think that site shows the stock springs are rated for someone ~130 lbs.

Personally, I would stick with their recommendations. I've taken my bike to the track and felt it was spot on. I think you can call them too and get some recommendations if you like.

 

did you do the work yourself if so how hard was it and if now how much did it cost

 

I didn't. It ran somewhere around $400 all said and done.
