RRE Camber Plates and Upper Bearing Plates

These camber plates are best used for cars running 2.5" diameter coil over springs. While we do offer them set up for use with stock diameter springs and stock upper spring perches, you will loose most of the possible negative camber adjustment because the bigger diameter spring will hit the inner strut apron. 

They are best for guys that need a lot of negative camber and change and adjust camber often. Every time you change camber, you will need to reset the toe in adjustment. Because of this, ideally you will have a grasp of automotive wheel alignment methods and have something to measure camber with. Something as simple as a carpenter's protractor will do it. 

While they can be used to fix negative camber caused by a car being stupid low, that is not their purpose. We'd like to see these going on cars that get autocrossed and go to time trials and open tracking days. 

A nice feature of our camber plates is that when used with coil over springs, they separate the shock load from the spring loads. Most camber plates will put both loads into the spherical bearing, severely shortening it's service life. We separate the spring load onto a flat radial bearing. All of the camber plate parts are available separately for service and repair.

KYB AGX Adjustable Struts and Shocks 

The new AGX series are the most affordable adjustable shock to fit your Eclipse. KYB's quality is top notch. The AGX shocks allow you to  tune your shocks to match driving conditions in seconds. No need to lift vehicle or remove anything to change settings. Damping rate is selected with an external knob on the shock body or a screwdriver slot at the top of the piston rod, depending on model. Lifetime warranty by KYB.

$525 set of four '89-94

$450 set of four '95-99 


Tokico Illumina 5 Way Adjustable Shocks 

These are our favorite for the 2G Eclipses. They are less harsh than the GABs or AGXs and more adjustable than the Konis. There is a 5 way adjustment at the top of the shock for both the front and rear shock for convenience. Turing the adjuster stiffens up both compression and rebound damping. Eclipse and Talon. Guaranteed by Tokico as long as you own your car.

They are available only for the '95-'99 $550 Set of four



KYB GR-2 Gas Shocks & Struts

KYB makes the factory suspension for the Eclipse, and these shocks are a great replacement value. These are a tiny bit stiffer than stock; definitely not a sports shock. 

$280 Set of 4. '89-'94
Set of 4 '94-'99


Eibach Pro Kit Springs

We strongly recommend purchasing a quality shock absorber along with these springs. They are approximately 20% stiffer than stock. The purpose of the shock is to control the spring energy. Get more spring & you need more shock. If you are on a budget and can't afford both, get shocks only for better handling. If your only purpose is to get all the chicks & look cool with a lousy ride, get springs only.

2G Camber Correction

Most tire wear problems are caused by not having an alignment performed after changing the height of the car. As the tie rods travel through an arc with any height change, the toe in of the tires change. This must always be re-adjusted with any height change. Most guys see the camber being negative and think that is the major cause of the excess wear on the inside tires. It is actually caused by the tires toeing out when the car is lowered. This will clean the tread off the inside of the tire faster than anything. 

2G Rear Camber Correction Kits  '95-'99

The rear kits are spacers and longer bolts that spaces the upper rear control arm out from the body to correct about +2 degrees. They are set up to correct for the amount of lowering you would get with the Eibach Pro-Kit springs. If additional washers are used, you can get a little more positive.

$40 for the entire rear of the car.

Energy Suspension Bushing Kits

These urethane bushings are stiffer than stock rubber bushings. They significantly reduce wheel hop and alignment changes under cornering stresses. While they can be quite affordable to buy, be careful what you wish for. They can be a major pain to install. They often require pressing or heating with a torch to remove the original bushings. Some of the bushings can be very difficult to get to. OK, now that we warned you, they do work. We use them on all our race cars and our own street cars, well worth the work.

Prothane Bushing Kits

Here is an alternative to Energy Suspension kits.  The bushings are red in color and stiffer than Energy stuff.  Well you ask, how stiff?  Rock hard stiff.  Boing !!! :-)  The full kit costs a little more than Energy but you get more bushings than Energy.  These are split bushing in design and a lot easier to install than Energy's one piece design.  You still have have to burn out the old worn factory rubber and take the metal sleeve out.  We only offer these in full-kit only and are for 2g (95-99) only Eclipse.

Prothane also offers the total motor mount replacement for 1g and 2g.  On 1g the rear, tranny side, and timing belt side is a total replacement.  The front is an insert only. On 2g's the timing belt and tranny side is total replacement, the front and rear is insert only like the Energy one.  We also offer the timing belt side and front separately, both 1g and 2g front and timing belt side are the same.
