           Rear $59.00/per arm (1 side)
These bushings when installed at their maximum
offset will increase your camber by 1 1/2 degrees.
We install them in the front upper control arms
because there is less force trying to rotate them
and we gain fender clearance. Grease fittings are
included, which lock the bushings in place.

We recommend you use the Bilstien if you are on a budget.
They are very good shock but are not adjustable. We have
them in stock.
We sell the JRZ for adjustable shocks.  We have used these
for 8 years and have had no problems with leaking nitrogen gas
or oil. The ones that are on my ITS Miata have been on there for
2 seasons and we have never needed to adjust the nitrogen
pressure!  These are rebuildable shocks.
We decided to redesign the sway bar system. The stock mounts are very weak, so we designed a
set that were must stronger and allowed the moving of the swaybar back and forth in several holes
for the pillow bearings. This allows you to keep the links up and down with arms. This is a
1 1/4" hollow bar with removeable ends. You could change the bar to a lighter bar for rain in no

Swaybar Mounts $175/set
1 1/4" Pillow Blocks  $27.50
The holes in mounts will not fit the stock mounts. If you
need to mount a different swaybar we have mounts.
We have Delrin Bushings for all the upper control arm and the rear lower control arm including offset
bushings to increase/decrease camber. We have Delrin bushings for the other arms you can install.
We do not believe in Delrin for the lower control arms.  When you adjust the eccentrics for toe(rear)
or for caster(front) the suspension bolts do not align up, that is why we install a spherical bearing in
the inner end. This allows the suspensions bolts to move the way they want to. We must install this
bearings, I have included the price for ready to go lower control arms. You can send me your control
arms and we can install them in your arms.
SPRINGS:  The SM springs (700# front & 325# rear)
will work on IT car.  We are currently using 800# in front
and 350# in the rear of our rentals. In my opinion, they
handle better with the stiffer springs. We use Suspension
Spring Specialists springs and they are $55.00 each.

                      $38.00/arm (1side)
We made these to eliminate the bottom of the shocks on the rear of Miatas.  We have raised the mounting point
of the shock to compensate for lowering the car.  The inside of the mount is hollow so the shock will go into it.
You can use a 3/4 bump stop inside, but we have used these in our rentals for 2 years without bump stop and
had no problems. We DO NOT use a bearing on the top.  The shock does not have a lot of angle changes as it
moves up and down, we take that out by mounting a rubber bushing on the top. The upper mounts  DO NOT
change the ride height, the springs do that. Because most people take out the original mounts, there is a difference
of about 3/4 inch that will drop the car.
We now make them in 1inch for
the front and 1.5 inch for the rear    
              $41 each
