Running the attached setup on carpet. Snowbird or just little smaller sized track. See picture.

The car has massive steering and is very stable in the rear but it is a little too hard to drive due to the steering.

I was using solid suspension block in front before and the car was more calm and very easy to drive but did not have enough moddle corner off power steering in the section in the middle where there are 2-3 tight turns. I tried 2mm bump steer shim instead of 1mm but the car was too twitchy and really hard to drive so I set the split blocks in front and got more steering everywhere however the car is too hard to drive due to all the steering it reacts too fast and too much.

Ideas to improve the middle corner steering and get a more calm car at the same time? Split block in the rear? 2.3 spring in rear? 2.7 spring in front? 350 shock oil? or other?

Ride 30 tires btw.

1mm on rear upper link

Based on Alex Hagberg's suggestions for Ride tyres, perhaps having some front anti dive.

You're not running a lot of droop in the rear. Try going from 5.6 to 5 or even 4.8. This will definitely help for the off-power steering that you mentioned that you were missing.

if you prefered the car when it was stable,i would go back to that set up and work on the lack of middle corner steering,i had my car like you describe and it was way to sharp even with 100% expo,far to nervous to be consistent, try 2.6 front and 2.7 rear springs with 350 oil,and play around with ackerman and toe out
