Hi Janis!
For me, one of the biggest changes to avoid the car leaning over on it's rear wheels and lifting the inside front, was CVA rear drive shafts. At first I used 22 2.0 shafts and hubs, with Ten-SCTE hexes to get the width to 250mm. This made the rear end better in all ways.
The thing is the universals have no binding, so the car feels softer, and doesn't square up under load. Some people like it, I hate it, and run the CVAs. The car feels more precise, and it reacts quicker to throttle input.
Now TLR has released CVAs for the 22-4, so I'm about to try that both in the front and rear.
Last year, I flipped the rear arms and ran the shocks in front of the tower, as did the rest of the team(
www.teamsmallsize.com), and we felt it did rotate a bit better. I'm back to stock right now for some testing.
For lower links in the rear, exotek has released both new rear hubs and a new rear camber block to allow for more adjustability
