Both the large and small chassis Audi's suffer from horrible understeer due to their inherently nose heavy layout. One way to mitigate this design flaw is to increase castor. Increasing castor causes the car to become more chassis neutral and allows the use of less static camber due to increased active camber gain under compression.
Back in the day Audi ran between 7 and 9* oc castor on their tarmac race cars.
This product is designed to allow you to replicate these numbers. I run 7* of castor in my RS4K track car and the chassis is now very neutral.
The kit is designed to utilize the ground Control universal 4 bolt camber plate system, however to provide increased adjustability in both castor and camber I developed a replacement mount plate for that setup.
The kit consists of a pair of weld in tubes and top plates that replace the factory strut top and the custom aluminum mount plate for the GC setup.
Significant fabrication is required to do the install but it is well within the capabilities of most of us here.
I can provide the kit as shown, or with the top plates welded to the tubes and finished, however this is an additional cost.
Again there are several people installing these over this winter build period and I will get feedback from them in the spring when they have had a chance to dial them in and test them out.
Horrible picture I will improve later, this pic also shows the steering arms and gusset plates.
