There will be no change in the allowed springs and rates. While the current rules produce a less than optimal suspension, everyone in SPB is faced with (discounting the use of the stock springs) just two choices. Adopting the proposal would raise that to four. It may be that some tracks favor one choice, and others a different one, and not everyone can DIY the alignment when done, or wants to spend the effort involved in sorting this out.

It looks like this is the cross tie bar they are using. It’s only $99 and the explanation for what it does to help makes sense to me:

I made my own for about 10 bux of aluminum bar stock. cant say i notice a difference but it was worth just for the fact that my aluminum underbody panel goes back on with no fiddling so in my mind it prevents some motion
