Piston Slap: The Fallacy of Miata Ride Comfort?

Hi Sajeev,

So I like my new 2010 Miata Touring (second car and half time daily driver), and picked it because it looked good on the side of the road by my house, low miles (19k), priced OK(mid 14′s), I had the dough saved up for a bike and I am happy with the current Vstrom, and last but not least it is an automatic. The OEM suspension seems firm to me but obviously not race ready. Roads in Northeast are usually not-so-new ranging down to horrible. Miata people say its mushy and floaty, those who want to autocross or race.

It's body is stiffer than my 1999 was. The 1999 benefited from chassis stiffeners- new frame rails, X-brace underneath, frog arms under the front fenders, door bars. Still a small noisy uncomfortable car for more than an hour. The 2010 is a bit more comfortable. For the 2006-2014 there are also aftermarket body stiffeners and plenty of suspension upgrades all meant to improve track performance.

What I really want is a GT, not a race car. I am not interested in more power.

Question for the best and brightest, should I bother stiffening the body on an automatic Miata?

What suspension would make it more civilized without less comfort?

Am I better off buying a true GT? What GT for $14k.

Sajeev answers:

When someone complains about a stock one, the words "Miata Ride Comfort" make no sense together. Instead do an LSX-FTW swap so you'll rarely have the time to focus on the punishing ride. And no, I'm only partially kidding.

To wit, a friend once asked if their Miata wouldn't punish one's lower back with the upgraded leather slip covers from a Grand Touring model: what a load of trash! Leather seats aren't magically wrapped around Fleetwood Brougham thrones, or even CamCord thrones. Time to suck it up and buy a more comfortable car.

"What I really want is a GT, not a race car."

Oh wait, you already admitted that.  Why? Chassis stiffeners cannot cut the impact harshness from a pothole, they help the suspension/steering/braking systems work as intended in spirited driving on imperfect roads.  Which totally isn't the same thing.

And if there is a softer-than-stock suspension (not likely) it won't help enough. Considering roadster levels of suspension travel, seat cushion padding, short wheelbase, light weight (to some extent), low-ish profile tires, a quite-modest sprinkling of NVH reducing materials…see where I'm going with this?

Go find a pre-engineered GT car!  A Mazda 3 or 6 sedan is a logical and practical step backward, but perhaps there are too many doors.  Maybe a Mazda 2? Maybe a somewhat used Mustang? Not refined enough.  A fairly used 3-series?  If you know a good indie-BMW mechanic and don't mind paying them.  A garage-queen C5 Corvette with Magnaride and conventional (not run-flat) tires?  Entirely possible.

 

 

Or just suck it up and maraud your way to love…
