New Dampers and Springs

The new Springs and dampers I purchased from SPAX look good. They were obviously built to order as they still smelt of fresh paint straight out of the box.

I've never used SPAX before but from what I've read and opinions of the people I've talked to they come with nothing but glorious reviews, matching AVO or GAZ the other manufactures I also considered for the Scimitar. 




The Dampers come with both an adjustable damping rate and adjustable ride height via the adjustable spring seat.

The disadvantage with this type of height adjustment is as the height adjustment is achieved via adjusting the position of the spring seat, this in turn manipulates the spring preload. This is one of the reasons why I chose the SPAX setup over my preferred choice AVO. The SPAX units came with helper springs.

Although I normally don't approve of helper springs and prefer a progressive spring on this type of damper without separate spring and ride height adjustment they do help to preserve the desired spring preload and while allowing ride height adjustment and not compromising right quality.

Obviously some detailed setup will be required in getting the damping rate and ride height correct on both the front and rear axle.




The Springs and dampers were assembled using the trusty coil spring compressor. This can be done with a smaller set of compressors, however this larger commercial grade compressors the whole coil with a single worm screw rather than two separate screws and  can be operated with a Impact gun and makes the  whole job quick and easy.

 A top tip is when using one of these large coil spring compressors is if you wish to avoid chipping the powdercoat on the brand new springs, you should wrap the coil in contact with the coil spring cups with insulation tape to protect it.

There is no need to compress the helper spring, they done add much to the total free length of the springs and have very little deflection. The helpers will be almost coil bound when the damper assembly is built  and will be fully coil bound on the car at normal ride height and only showing a small amount of deflection during droop.



An obvious upgrade on the original dilapidated KONI units.
