Custom sway bar end links for the Mazda Miata
Until now, every solution for attaching the sway bar to the suspension
has made what are to us unacceptable compromises.
The stock, rubber-bushed links bind as the car rolls: this is especially
a problem at the rear due to the links' more extreme mounting angles.
This increases the rear sway bar rate in a non-linear fashion, which
adds to the Miata's tendency for roll-oversteer: in simple terms
this means the more the car rolls in a turn, the more the rear end
wants to step out.
The aftermarket came up with Heim-jointed end links, but there's
a problem there too: the sway bar end is a single-shear mounting
point, so just bolting a rod end up to it is not the right way to
go. Binding, accelerated wear, and bolts wearing and working loose
can be the result.
Here's our solution (actually, we have a few.)
First, we present the heavy-duty solution:
A permanently sealed ball joint threaded to a high-strength Aurora
rod end. We originally came up with these for a Miata rally car,
so we know they're likely overkill for the street or track. We can
make them to any length, so if your car is very low you can still
properly adjust your sway bars. This picture is the first prototype
set we made, and as you see them here is after six years and several
thousand miles of use... many of them on the track, so that's more
like dog years (dog miles?) to the average driver. The only drawback
to these links is they're expensive due to the cost of the component
parts: that led us to...
End Link, Version 2.0:
A more afforable alternative with the same functionality.
The ball stud has a dust seal but it's not as permanent as the heavy-duty
model, so these will require occasional cleaning and lubrication.
This model incorporates a jackscrew which makes on-car adjustments
Here's a set being tested on the front of our project
The Version 2.0 and later endlinks are available for
$75 per pair.
COMING SOON! Pictures of our Endlink
Version 2.5, which allows use of any swaybar (including NB bars)
in NA chassis, and out Version "2.Low" for very low cars.
and we'll build a set for you.
