For the upper mount I wanted to forgo the stock bayonet style mount and use the 1/2” spherical bearing on the Koni shock. To achieve this I cut out the old shock tower top and made a new one to accept a 1/2” through bolt.
This all ended up taking a little longer than expected because I got into a pretty bad case of “while I'm in here.” I ended up stripping all the undercoating from the rear wheel wells, the paint from the trunk floor and rear seat area (both areas were pretty ugly), stitch welding the shock towers, and redoing the plumbing on the rear half of the fuel system. In the end though it was all worth it, and the rear interior area of my car is much prettier.
Back to the coilover install. My initial impressions are very positive. I have the shocks set at the softest of their 4 settings and the car feels very well balanced. Mid-corner bumps have a much smaller affect on the attitude of the car in it feels much better in transition. I was also a bit concerned that the solid mounts would be a bit clunky, but things have been silent so far. I'm looking forward to seeing how these perform at the first auto-x of the year in about a months time.
) I was pretty sure that most of the off the shelf setups available wouldn't work. Another big reason was support. Circle track racing is one of the most popular forms of racing in the US so using parts that are typically circle track parts opens up a huge base of aftermarket support in terms of shock revalving, etc.
