Redshift coilover users, lifespan between rebuild/refresh?

TLDR version:  For those who run Redshift on an auto-x/street car, how long do you go between rebuilds, what are your road conditions, and how often do you drive it?

Rambling on:  So, being super happy with my Feal coilovers over the last 4.5 years, because they work real well for me AND they were inexpensive to run (I'm cheap, I know there are a few of you cheapos on here), I was bummed to learn rebuild cost has jumped from $100 or $125 a corner to $225.

For a sometimes dedicated auto-x guy, they were a great way to participate with a responsive car on a budget, especially since I factored that "total cost of ownership" in.  At the initial buy in, and factoring in rebuild cost, and that rebuild cost would increase over time,  I could've gone buy-in plus 2 rebuilds for the price of just initial buy-in of the "big boys" that live on the Miata suspension block.

The question in the header topic relates finding a similar payback scenario going forward.  I've been interested in Redshift anyway, so  want to know what others' experiences have been.

Redshift rebuild cost is the same as Feal, but, if they lasted somewhat longer between rebuilds, it might be worth pulling the trigger on a set. 

Unfortunately, I can't just swap cartridges, because it looks like Feal is a 50x1.5, and Redshift/BC is 53x2.

So, let me know use, road conditions, and longevity if your car is a dual purpose street/auto-x car.  Tucson has a lot of bad roads that mean you're driving on washboards a lot, so I only get 2 years between rebuilds, and the car is NOT a daily.

Or if you have NA/NB Miata BC Racing units you're getting rid of since you no longer need, I'd take the hardware and grab fresh cartridges from Redshift...

Let me know!

I've had mine on the car for approximately 1000 km and they don't need to be rebuilt yet 

I would send your question to them, Chris probably won't get back to you right away but he will answer your question. He can give you some feedback on the difference between his product and what you are currently using.

Speaking of which, has something changed with your current setup that you've notice the performance go down hill? Are they leaking? 

My experience with the Redshifts compared to the Fortune Auto I had before has been a big improvement. I have the competition setup running the same spring rates as before. What made me spend the money to change is a flaw in the FA setup for the E28, for some reason they spec very little stroke in the rear and that was causing problems and the car generally felt unsafe on any sort of drop in the road. The Redshifts ride a bit stiffer than the FAs when they are set to full soft but the ride is very acceptable on road. The FA in comparison felt awful at full soft, the car felt bouncy and uncontrolled, I ran them about 1/3 of the way from full soft just so they did something. I like that the full range of adjustment with the Redshifts is usable. On our super bumpy autocross course I left them at full soft and the car felt the best it ever has there, very controlled, composed and did exactly what I asked, last year on the FA it felt like I was just hanging on trying to drive around their shortcomings and it honestly wasn't enjoyable. I've only had a few sessions on track with them, they felt good but I didn't get a chance to play with the settings other than putting them to the baseline provided, my head wasn't in it either doing an instructor training school that weekend. I do expect them to do well and look forward to dialing them in.

All that to say I am very happy, the BC hardware is nice and their baseline setup for an E24/E28 is miles ahead of FA (it's like they actually did some research and properly setup the stroke etc unlike FA). The Redshifts feel pretty serious when you start to twist the knobs up, my first drive I had them set right in the middle and it was uncomfortable on our not so great roads, I was relieved once I set them full soft and the car rode decently again.

I know it's time for a rebuild when I forget to dial back the settings after auto-x, and realize after a few miles of driving home that the car feels the same as it did on the way there when it was set close to softest settings. 

I figure they're in need when turning the knobs has no appreciable effect of the cars behavior.  When they're fresh, I know immediately.

However, when they go, they still feel pretty decent, but they feel like a non-adjustable damper. 

Performance wise, when they're fresh, they handle like you describe above.  It soaks up imperfections without upsetting the car, the car has never felt unstable in "whoop dee doos", I enjoy how they perform.

Refresh every couple years at $4-500 is pretty easy, double the price shocked me a bit. 

So, with Redshift rebuild at the same cost, if I can get three years between refresh vs two, well, that's worth a look. 

If that makes sense...
