The before shot. Notice the 964 oil tank installation. (never have gotten around to posting a thread on that one)
The Elephant Racing Poly-bronze are currently installed, which are great, but the Wevo SPS has some distinct advantages. And of course, I got a great deal on them since I now work for Wevo.
With the old springplates out, and the opening cleaned of all the dirt/rust, It's time to fit the inner bearing carrier. I scribe a mark on the carrier, and tape a mark to the car so I can keep it indexed properly while shaping the carrier to fit the opening.
Checking the fit of the cover to the mounting spuds. Luckily, mine are flat, and straight. Usually it's necessary to straighten them to line up properly with the holes on the cover.
I'm also lucky, in that I only required shimming on the lower rear mounting point.
One thick, and two thin shims makes it perfect. After tightening everything up without the torsion bar in yet, it moves freely with no pre-load whatsoever.
Here's the right side completed. An added bonus was the fact that I can install the torsion bars after verything else, which made it possible to install the SPS without having to remove the oil tank. Normally, with a stock spring plate, the torsion bar would have to go in first, which would've required more room to get the spring plate over it.
Left side nearly completed
Now all that's needed, is to put the angle finder on the springplate, hold the spring plate at the angle that I measured the old one, and slide the torsion bar in. Mine are hollow, making it even easier to turn to just the right position that will alow it to slide right in at the appropraite spring plate angle. Fine adjustment can be made with the adjuster screw to get it perfect.
I always hold upward pressure on the spring plate during all angle measurements to take out the slop, and make it as accurate as possible.
Note: Due to the lower amount of stiction in the SPS, it will actually raise the ride height by 10mm typically. I compensated by reducing the spring plate angle by .5 degrees.
