After my track season in 2012, I had the 944 pretty solid mechanically and had all the safety gear installed that I wanted (full cage, Hans device, 6 point harnesses, Joie seat, fire suppression system, master cut-off switch, wink mirror). It was time to spend some money on some go faster upgrades.
In a previous post I discussed my spreadsheet that can be used to predict the total front and rear suspension response. I was able to confirm the validity and balance of the 944 Spec 1 Koni suspension set-up sold by Paragon Products. It includes: front and rear Koni shocks, Weltmeister adjustable front and rear sway bars (28 mm and 22 mm), Hypercoil “coilover” front springs, and Weltmeister rear torsion bar. I went with the 30 mm rear torsion bar and 350# front springs. Here are some installation highlights:
First I tackled the front. I already had the front suspension dismantled in order to replace the rod bearings. I started by mounting the new sway bar. This turned out to be a puzzle because Weltmeister included the written instructions but forgot to put in the associated diagram. I was able to figure it out eventually. Most of the parts bolted up to existing mounting points. On my car, I had to drill holes into the steel A-arms for the mounting holes of the drop links. Here are some pics:
The stiffness of the bar can be adjusted by sliding the drop links back and forth on the sway bar end.
Next came the coil overs. The parts will fit up to my early model strut tube with no modification. That said, per the advice of Jason at Paragon I decided to cut back the spring mount to give better access to the height adjusting ring.
The new yellow Koni strut cartridge inserts cleanly into the strut tube. The directions were not clear but the pictograph is trying to say “Add some anti-freeze to the tube”. Jason says this helps heat transfer from the hot cartridge during heavy track use. You put the screw on cap back on. But before you do this, install the spring height adjustment pieces, as they won’t fit over the cap. Then you can set the spring into place and install the bump stop over the shaft. Here are some pics of the installed pieces.
