RX8Club.com - Coilovers... Rebuild Questions

So now that my car is coming on 3 years, I am in that phase where I am really starting to organize my future maintenance expenses. One of those expenses that I considered is a coilover rebuild / revalve.

I am running Stance GR+ coilovers on the car, with Swift 11K / 6K rates. The coilovers have about 20-22k miles on them. They have been used mainly on the street, and 1 1/2 seasons of autocross. I have never had the dampeners set very high, and I try my best to not drive on garbage roads or hammer through potholes.

I contacted Stance and got the following quote:

Quote:

Price is $195 for rebuild, $35 for revalve.

For normal street driven car, we recommend rebuild at 60,000~80,000 miles.

You can also purchase new dampers at $205/ea. This way you won't have any down time

If you get the dampers from us, I can waive the revalve charge.

You would need to transfer over the rest of the parts, springs, locking collars, mounts, brackets etc. It is fairly easy.

It was refreshing to hear that they recommend a rebuild at such a high mileage, but as we all know, there is no 'magic number'. One thing that throws me off a bit, is that it would cost me more to get a rebuild/revalve than it would to just get a new set of dampers from them valved at my specs .... didn't really make sense.

Anyway, the bulk of my question is this for those that have experienced failing coilovers:

- Do you do a rebuild just as regular upkeep? I know many of the dedicated track folks rebuild every few seasons.

- Visible way of diagnosing failed shocks, leaking. Physical way of diagnosing failed shocks, loss of dampening over bumps (bouncy bouncy bouncy). Now these are very basic, but is there anything else to look for?
