How long is the Bilstein suppose to be good for? I wonder I should start saving my pennies for the next set. My 99 Sport already has 110K on the clock. I do not think they are going bad. On the other hand, I am driving it everyday and is hard to tell when they are going down hill.
I'm pretty sure they'll leak when they go bad.
When your car hits bumps and its more harsh then you remember or if you push down on the front or rear and the car bounces more than once, like several times, its probably about time. If your car has that many miles on the original shocks, its about time to invest in some new ones.
I doubt that you will ever see the bouncing effect on the Miata. A Ford, Yes. But the Miata. your more likely to put a dent in the fender trying to push the car down on the springs.Quote:

Bilsteins are good until they leak.
Mine have 160k+ and are still solid (even after 50k slammed w/FCM Bumps)
Bilstein will factory rebuild them if you want.
I'd Call Shaikh, at FCM
He is the Bilstein Guru!
He can rebuild them with custom valving if you want.

Yeah I've been reading a lot about his products. Wish I knew about those bumpstops when someone installed my shocks. :rolleyes:Quote:

If I needed work done on Bilsteins, I give him a call and discuss options at least...
I’d be leery of any shock with 100+k miles on it, Bilstein or otherwise.Quote:

By 100k miles I’d be willing to bet that your Bilsteins wouldn’t look anything like a fresh set on a shock dyno.
Sometimes it is hard to know when a shock has gone bad, especially if it doesn’t fail catastrophically. The shock can lose damping in very small increments from day to day to day. The change from one day to the next is small enough that you’ll never notice, even though the cumulative change from new can be quite large.
The good thing is, Bilsteins can be rebuilt and revalved inexpensively.

Mine have 160K+ on them and still feel fine but one day I may pull them off and have them rebuilt/revalved. I wish I had a fresh R package car to compare it to.
Thanks for the opinions! I agree with altiain that they may be still feel good on the street, but when compare to when they were new, there may be a big difference. I would hold off getting they revalved if don't AX or going to the track. I think I will check into getting them done by FCM.
