I tried to get the best explanation for the correct OEM spring rates changes over the years after spending several hours looking for information, mainly because it was bugging me

According to Honda
00-01 to 02-03 ( The UK Press release states

 

Good info, thanks. I agree, the correlation between SCC's measurements and the numbers Honda's percentage changes indicates a high confidence in those numbers.

That roughly corresponds to 7 kg/mm front and 6.25 kg/mm rear for the CR.

 

So that's why my cr is so stiff.
great post. This should be a great thread to reference to.

 

or this one for example

Official Springs Thread

 

The CR shocks are significantly stiffer than the stock shocks, that makes a difference as well.

CR Front: Damping Force Increased 50%
CR Rear: Damping Force Increased 32%
(from 2008 spec)


Check your tire pressure, it's not uncommon to see 45psi from the factory.

 

Maybe you missed it. That was the point of this thread. The thread you linked to has incorrect information. The OP was trying to clear that up.

 

Honda had published that the 02-03 had 20% stiffer front springs and 10% softer rear springs, so there isn't that much of a mystery. The UK information is probably only talking about the front springs.

The sway bar rates are easy, you can find them in the parts section at the dealership.

 

good work

 

good information

 

I am sure everybody on the board including myself would be delighted to know if this is true, as it simply takes the ubiquitous guesstimate about the 02-03 spring rates out of the equation.

Anyway I am also sure that this information you posted about the % change in the 02-03 spring rates is news for the majority of us, and I hope its true, but could you kindly point us to the source of that information?
