Hi gansei,
Good work
Our weather is too bad to do anything !
If you dont have too much track grip I would suggest having bigger holes in your shock pistons, or maybe thinner oil.
Also on the rear camber link, maybe you could try 2 shims on the hub, with the inside in the middle inside hole. I think you will be able to run less rear camber to get the tyre wearing nice. Putting more weight on more of the tyre.
Do you mean having the wheelbase short front and rear ? If so I think this is very short, maybe a little more tricky to get the car balanced with the shortest wheelbase ?
Good luck
