Post M030 upgrade from boge

I would like to upgrade my worn suspension with some Koni coilovers in the front and rear. Were all of the M030 struts threaded coilovers? Where can I get a set of these struts and shocks? Anybody want to sell me a set????

Justin, there are quite a few ways you can go. The M030 front struts/springs will bolt on your car. There are also aftermarket coilover applications that will be more wallet friendly and there are others that are even more performance oriented. Remember that the 951 M030 cars did not come with rear coilovers, that option was reserved to the 968 M030 cars. [email protected] Paragon Products

What are these more "wallet-friendly" options?

When thinking Koni and height adjustable, there are two approaches to attain coil-over fronts.

One is the M030 sealed strut (originally single-adjustable and ride-height adjustable, though are resold as double-adjustable now). This option allows you to use the original springs (~150 linear), cup springs (~160-410 progressive), or add the correct perches to allow use of the 2.5" springs (100-1000 linear).

The other is to retain your Boge strut casings and fill them with Koni Sports (8641-1414S) and then add a coil-over adaptor kit to the outside. This sleeve will now allow you to use 2.5" ID springs (which can vary in spring weight from 100-1000 lbs).

Generically, the price difference is ~$450 cheaper for the non-M030 approach, but you will not have the added bump adjustment and the valving is a bit softer on the generic 1414S strut, though certainly not inadequate for most uses.

Good Luck!
