Kyosho Small Bore Springs

[neallewis]

I'm after some clarification on the ratings of small bore (zx-5) springs:

I've seen conflicting information regarding the rate of the Silver fronts (w5181-09) some tables say 3.30lb/in, some say 3.75lb/in. Also I can't find a rating for the cobalt rears?

A lot of the multi-vendor spring charts include the same data, so one was taken from the other. Mistakes are duplicated, however.

There is this: http://www.oople.com/forums/attachme...7&d=1198454439

I just want to see a complete rate listing for the entire range of kyosho springs. Can anyone help please?

Ah actually that last attachment I posted has the cobalt rate!

So ok, it's clarification on the silver fronts rating I'd like.

Reason being I've seen them being run on Associated shocks as alternatives to the very short AE silvers. I've been told they are a very similar rate, but if the charts are to be believed, they aren't?

The Kyosho silvers are between the AE silver and AE blue rates, nearer silver.

I measured, using a £50k indutrial compressive test machine, a load of springs form many manufactures a couple of years ago ... just need to remember which website has that information on it!

From my experiments so far virtually all the big bore spring charts are wildly wrong (same machine as above) but unfortunately I didn't get offered many sets of big bore springs to measure when I had time and now I no longer have the time to do so. Maybe in the future.

I thought they were 3.7-3.85
Rich Lowe has since advised me there 3.30
Weird
