Reply to "Koni Shock absorbers for Mangusta"

That's a good find Larry.

In our case the difference is just enough to be annoying and there are a number of ways to skin this cat as they say.

The QA1 shocks come in two styles; spherical rod end or rubber bushing. Both have an imperial I.D. of 0.5 inch and the stock Pantera metric mounting and bolt shank is 12mm diameter. That's a diameter difference of 28 thousands of an inch, or a bushing lip insert that is only 14 thousands thick, pretty thin.

In either case you can drill the Pantera mounts to 0.5" diameter and source the correct length 0.5" shank diameter bolt and some 0.6" long spacers to keep the shock centered in the mount. Problem solved if you don't mind modifying your car.

If you have rubber bushings style you could fabricate new inserts from some 12 mm I.D. tubing with 16mm O.D. (I believe the I.D. of the rubber bushing alone is 0.625" or 16mm).

QA1 sell various spherical bushings and rubber bushing insert kits, but unfortunately they don't know what metric is or assume their shocks won't be used on import vehicles. I reached out to them and they did say that they can come up with a 12mm I.D. insert if you have the bushed style shocks.
