Steve:

Spring CoilBound Travel Limits

0700 250 0450 = 3,57
0700 250 0550 = 3,33

Your Formulae yield the following resting Travel utilized:

0700 250 0450 = 2,66
0700 250 0550 = 2,19

Thus there would only be available Spring Travel of:

0700 250 0450 = 0,91
0700 250 0550 = 1,14

Equating to available Wheel Travel of:

0700 250 0450 = 1,36
0700 250 0550 = 1,71

To Me, SEEMS there is much more Wheel Travel available under real World conditions (via Observation, I have NOT actually measured) and wonder if the Formulae are too simplistic?

I ran This by Jay once when discussing Wheel Rates and He said there was much more to It....

I think your calculations are close. I removed my spring and with a ride height of 13inch the rear wheel travel is about 1.89 inches when the shock contacts the bump stop. This is with koni d/a and GC bumpstops.

talking about ride height, and the effect that a heavier spring has on it...

so if changing springs, how either raising or lowering the collar to compensate may be in order.....

I talked to Jay, and my question to him was......changing from 450 to 600, how do we calculate how much the perch will need to be raised or lowered....
