Miata Dampers - What is the 2X amount?


Recommended Posts

So depending on where you look and which damper you choose (could be Bilstien from factory) I have seen anywhere from $35/ea to $150/ea for stock replacement front dampers at Autozone online for example.  This would then dictate a 2X value of either $170/ea or $300/ea.   So I recall using the higher price in the past but I want to confirm this bc for the miatas, its pretty much only Bilstiens for anything decent under $300/ea.  Lots of options over $350-400 though...

 

I just want to make sure that I dont use an unrealistically low or high number and either lose out, or risk a protest.

I can order Bilsteins for $120 each once they are back in stock.   I don't think you can find expensive enough non-adjustable shocks for a Miata to get yourself in trouble.  And if you did, why?

Therein lies the issue with 2X. Easier just to put a limit on struts and shocks for everyone.

Like the series says only manufacturer X and series Y can be used.  If manufacturer X does not make series Y for your car ask for an apporved equal and then it gets added as an addendum to the rule?

 

Sounds like work, better just let the teams worry about it.

I recently read a post by a ChampCar colleague wherein he stated that his 2x example was denied because it used words similar to "performance upgrade", "high performance", et al. 

I would think that any strut or shock that is used to set 2x valuation for a replacement should be considered an "OEM replacement" or "stock performance" unit. At least, that's what we've gone to great length to document in our "build book" for the new car. We have 3 examples of struts/shocks that fit within the 2x rule that are noted as a stock-equivalent or replacement shock. They're not the cheapest, junk Monroes you can buy, but they're also not "upgrades" from stock.

Correct, that was me, here is what was denied for the Mustang because of the words "performance" and "improvement":

  • Entry level performance shock absorbers & struts 
  • Perfect for OE replacement or vehicle improvement

And here is an example of something that was accepted:

  • Recommended OEM replacement shock for performance cars
  • Specifically calibrated to help restore the original handling and control characteristics of the Ford Mustang
