Constructional Criticism Please :)

[Norm Peterson]

Just to echo the concern about having the D/S loop carry the entire UCA load - I have lots of doubt, even at only street levels of grip. If you feed that load into the floorpan, you'll need to spread it out over some distance. What you're proposing as reinforcement is certainly do-able, but it's much like adding a suspension pickup bracket to a monocoque structure. Keep in mind that the stresses need to be kept fairly low, for reasons of fatigue life. As a really rough approximation of how much load is involved, that upper link carries a similar tension load under acceleration as either lower does in compression.

Actually, there's substantial argument for putting a bigger rear sta-bar on for your strip passes than you'd use for the street or any corner-carving events. What that does is use the engine torque reaction carried back through the chassis to return some of the load to the RR tire that the driveshaft torque reaction removed. Disconnecting the front bar will help this effect in addition to lowering the resistance to rise (the reason that everybody thinks of first is not the only reason). Given that the pavement is equally grippy in both wheel tracks, equally loaded rear tires will out-pull an unequally loaded pair with the same total load. Even with a spool.

Longer links will slow down the rate of change in the anti-squat, and converging the lowers makes the rollsteer less sensitive to changes in ride height.
