I want to go this route, but need to know who sells them? I've been unable to find it on the net. (for a SC front suspension)

Also, how difficult is it to do on your own and how exactly is it done? (IMG:style_emoticons/default/sawzall-smiley.gif)
Does any one have any detailed pics of a raised spindle shock/strut?

The stock suspension was set up for adequate performance within the constraints of a passenger car. The lower a-arms are too short thus causing the roll center to move all over the planet when the car goes into roll. The radical changes in length as it goes through travel can create a wierd sensation for the driver. Most race cars run such high spring rates and little suspension travel that this is not a problem, but 914 race cars still have a pretty high degree of travel compared to other types of cars. Another problem is the bumpsteer issue that we are all familiar with. Raising the spindles only makes this worse. The spacer kits only work with a limited range of bumpsteer correction. The proper way to adjust bumpsteer is with a kit like the ERP kit. When you bend the steering arm you shorten the arm as well. Thus changing the steering angle.

Since the front suspension is the easiest to change it tends to get more attention than the rear. The rear suspension has a big problem of toe change and roll center change when you lower the trailing arms past level. When the trailing arms go past level through their travel they load and unload the front wheels.
Imagine a broomstick. When you take this broomstick and hold it straight out and push against the wall what happens? Nothing. Now take that same broomstick and hold it at a 15deg downward angle. Lean on it. What happens?(watch out for the wall) The same thing happens with the rear suspension. When you roll into the power the rear suspension, that is at the wrong angle, will cause the chassis to lift or drop and it will unload the diagonal front wheel. When you unload a wheel you lose grip and the car will no longer turn. Welcome to "pushville".

I am working on the numbers now but I am not done yet so I can't/won't share anything concrete right now, maybe later.
