Thank you for the info WJBertand.
I called Racetech.com today after going to their website and calculating the best spring for a 240lbs guy.
The resusts put me on one before the last from the list
SK SPRING 8.0 x 2.25" 19.6kg
(See on top of the page recommendation)
So...
(1) rear spring $125.oo
(2) spacer adp $23.oo (recommended)
I dont know the mm on the racetech spacers, if I go with the Eibach spring it means can I get the spacer from rideonadv?
Now the problem is thr spacer!
Thank you.
