Clarification on Spec Miata Penskes

Recommended Posts

What makes you think this? just the name?

Think this is probably based off of what’s available to read about these shocks.  They are specifically being built for spec Miata’s.  The hype says they are wonderful   We don’t really know until bunches of them are in use.   It’s a funny thing marketers never say “hey we bought the rights to sell all you folks shocks and threw a POS together”.  I suspect they are pretty good though

Wouldnt the Penske shock perform better than a KONI yellow or other single adjustable that falls within 2x? The R&D on the Penske shock is going to be much more than the cheaper single adjustable. 

The same can be said for Bilstein B6/B8, shock dyno testing we had done has shown them to be better and more consistent than Koni yellows.

And B6's/B8's can be bought nationally at Tire Rack, Amazon, Summit Racing, Auto Anything etc...

 

Where can I pick up these Penske's nationally besides Penske themselves or Mazda Motorsports?

So far it's all hype though, right? The only people saying they are wonderful are the same people selling them. It's not like this is the first spec series ever that got it's own custom built shock. Not saying they aren't great, but is there something really unique or special about them that wasn't available before? If they just did more work to better fit the application that's just a benefit of being on a popular platform, it's not really unfair to anyone else.

So what? Should we ban tires that are exclusive to Tire Rack? They are still available to everyone.

4.8.1 😊

 

 

Clearly that rule doesn't mean what you think it means.

It applies to pricing on stock parts relative to the 2x rule. It doesn't mean that parts bought for a race car can only be bought from national auto parts chains. 

S.

These have the same internal components as other Penske shocks.  Same pistons, shafts, bore finish, seals, and shims. They will perform the same as an equivalently valved double adjustable 8300 series. The high end components will reduce hysteresis improving the overall grip and reducing tire wear regardless of the valving.  Because of this, these will be much nicer than a Koni, Bilstein, or other mid grade damper even if the valving is t quite right for your application. Damper hysteresis doesn’t get the credit it deserves.

Anybody doing any performance stuff in a Mazda should be a Mazdaspeed member, it's ridiculously easy to be part of (min. 1 event autox and up in the past year, or intent to build a car) and best value for many stock and performance parts. Can't be mad about a manufacturer that supports about grassroots motorsports.

Damper hysteresis doesn’t get the credit it deserves. 

"In a recent dry- and wet-weather session at Carolina Motorsports Park, pro drivers Joel Miller, John Dean II and Randy Pobst tested Penske’s race-engineered shocks head-to-head with offerings from several other brands over four days. Three different versions of the Mazda Miata were tested, and runs were made on Toyo and Hoosier tires. Test drivers didn’t shy away from curbing, running the cars to simulate qualifying and long runs. In all, 72 different combinations of driver, damper and tires were tested.

Results show the new Penske shocks to be similar in qualifying lap times compared with shocks currently used by the SM field. But on overall pace, particularly starting on the fifth lap, the Penske product showed brilliance. And on 30-minute to hour-long runs, where the current spec’s lap times slowed by three-plus seconds on the high-wear track surface, the Penskes never fell off to even two seconds compared to qualifying lap times. An in-depth look at the test findings and process can be viewed here."

 

So worth more than a second a lap in an endurance race.

 

Good thing these fit on a Fiero. :lol:

So does this make any Non Adjustable Penske or like Shock legal for other marquees as well?

This is a fair point that should get clarified.

Wheels, brake calipers, brake rotors / drums and nonadjustable shock absorbers are open, PROVIDED they meet the “2X Rule.”

• Shock absorbers / struts over the 2x limit and/or with damping adjustment, 25 pts per corner

Are they adjustable? No

Are the > 2X? No

Then they are zero points, non-adj shocks are "open" that would include what ever busing/seal/piston material they incorporate into their design.

You are right but it is easy to see where others seek techs advice.

Good point, I like where your head it at.

When one of you Miata runners splurges for a set of these fancy Penske shocks, we will happily take your old Bilstein B6/B8 shocks as a donation for one of the Chandler School Miatas that has some brand unknown POS shocks on it. We wouldn't want those old yellow shocks cluttering up your valuable shop/garage shelf space 😉
