While I don't claim to fully understand the geometric reasons as to exactly why, here's what I've found. With the standard pivot blocks, I struggled to gain enough forward drive when traction started to drop off. I tried everything I could possibly think of- more anti squat, less anti squat, raised links, lowered links, softer springs, softer oil, long links, short links, and more combinations than I can even mention. The end result was always the same though: if I got the car to be stable on entry, forward drive suffered quite badly and there was usually an apex push. If I got the car to react nicely near the apex, then it was terribly loose on power and any point following the apex.
With the LRC blocks, I can run more anti squat to gain that forward drive, and a shorter link which also helps with that. When I tried this combo with the standard blocks, it was terribly loose on entry. With the LRC blocks corner entry is more stable, apex rotation is more controlled, and forward drive on exit is far better. For medium to low grip tracks, its the best my car has ever been. I was on the verge of offing it as I has struggled mightily, but I'm happy now.
