Oh, it does work well, if you're out getting groceries or hitting the dragstrip. Throwing it into a corner is another matter. We get grinding noises in left turns (no witness marks mrom tire contact), and short of throwing new arms at it repeatedly, it stll comes down to roll-induced bind. Using bushing torsional deflection is just not the right way to locate an axle laterally.
As for Ford leaving the design alone, yes, they did, but I would bet BIG money that it was a cost-based decision, and not performance-driven. 90% of the people that buy Mustangs don't race them. And 90% of those that do, don't turn in their chosen form of motorsport.
Hmmm, you mentioned grinding noises when turning left. At the beginning of the race season last year I started getting a grinding noise behind my seat somewhere in the middle of the car but slightly back by the axle. I thought my driveshaft was rubbing on the safety loop but no signs of that.
I was getting the grinding noise on hard fairly high-g right turns, not so much on left but I cant completely rule it out. I'm wondering if that noise I'm hearing (last year and this year) is related to the binding issues. I'll need to get under the car and check that out a bit closer.
