thanks...
to be honest, We are doing a couple of changes on the suspension since August 2018. Unfortunately, rear independent suspension didn´t perform as I wished and there were a couple of problems caused by a mistakes made be the producer.
We have made an analyzes of the suspension - everything measured by Dynatune XL
- strength analysis
- kinematic test
Both were not good, so since this time /August 2018/ the car is at Profi Performance

rear arms were too short and the suspension was not strong enough. Depending on this, the axles has been twisted by the forces in the corners and small arms were changing the toe and camber by stroke and load significantly.
So We have made a brand new independent suspension - used just the "trailing arms" from the "old" setup - rear axles are finished and it works how it should. Everything was measured many times by Dynatune XL again... To make them strong, producer spent many hours making the tests and We have to streght the trailing arms too...
starting basic geometry on the rear axles are:
toe: 0
camber: -2.2 degrees
kinematically it works great, doesn´t change TOE and camber at all by full stroke or load /most of OEM cars do change toe by stroke or load/
We will change also the wheel bearings - from small to modern simple big bearing setup. We will use AUDI wheel bearings... Why? now the point where it´s twisting the axle is at bearings. Bigger bearing will be stronger, the wheel will be guided more precisely /more accurate/.
Kinematics of the front suspension is not very good also. So We are working on the front axles and steering now. Trying to get there more castor, working on the brand new front spindle-knuckles... Should be ready in January/February
Also will change the springs - they were analyzed also and setup will be slightly different considering the new weight distribution of the car...
