Parallel or triangulated 4 bar??

[Norm Peterson]

The single upper link carries about the same load as either lower. Not double like people tend to think because there's only one. Still, and especially with a powerful engine and decent grip, you'd want to have enough difference in the heights of the UCA and LCA pivots to keep the loads as reasonable as possible or practical.

It's probably easier to build enough anti-squat into a 3-link for dragstrip duty without screwing up the handling than it is to make either a dragstrip-based 4-link+PHB or an OE-based triangulated 4-link work very well through a slalom.

Another 4-link option is the AME triangulated 4-link, which appears to be skewed more toward turning corners.
