To get that back that stiffer handling, match the suspension to the new tire, just like BMW did by building a soft suspension around the RFT. Understandably not a simple job, but this is the track and AutoX board after all.

I think you are talking very small differences. I am really talking tire matched to suspension tuning. I chose the PS4S for its traction formula but it has threw off the feel and made it too soft and now am looking for new springs next year. |
Not small differences at all, the car on RFTs could not hold up to a half day of AutoX, let alone a day of HPDE. The increase of slip angle by even a 10th of a degree has a large impact on cornering.
