I suppose there could be a third option - add a washer to take up any extra space between the LCA and the bracket if you decide to spread the bracket a bit. But this is definitely a last-choice option.
Norm
Looks like you have two options - either resolve the dimensional issue with Ford Racing/Ford Performance as being yours are too long, or grind a sixteenth off of the spacers you have.
In any event, make sure that the inner sleeves that run through the polyurethane are just a little longer than...
Does the noise go away if you raise the rpms up a bit? Does it make noise when rolling along in 1st gear and little or no throttle? Have you checked the transmission fluid level?

Koni STR-t dampers are not adjustable. Koni Sports (aka "yellows") are adjustable, but only for rebound, which isn't going to help bottoming on dips in the road.
I have no idea what "DUB springs" are - never heard of them before - but if the brand name is any indication my guess is that they...
You can get 295/35 tires mounted on 9.5" wide wheels, but it's not recommended. 295/35 tires really should be on wheels that are at least 10" wide (better yet, on 10.5" which is the "measuring width" for that size).
Norm
Impression I get is that the pilot Super Sports are slightly better than anything in Nitto's 'Passenger tire' category even for the straight line stuff. Way better in the wet, if that's any consideration. In Nittos, you really need to be looking at the tires listed under the 'Competition' tab...
Stock mufflers, either as take-offs or from a salvage yard. You may or may not be in for a little 'adapting' depending on the pipe size used by Pypes.

If I was going to be generous to Ford, I'd say it was a case of sloppy tolerances or poor quality control on something down there.
Straight off the truck, something about the CPP on my '08 made it nearly as bad as what you described for your new one (pre-MacGyver'ed). Like the car would stop...
A cable length adjuster would be a neat trick for the kind of clutch "cable" that's hollow and gets wet on the inside :D
I didn't see any mention of making the adjustments that you're looking for in my 2008 shop manual, and I doubt Ford changed much between '08 and '11.
The easy alternative...
Relo brackets apply more torque to the axle tubes because they act on a longer lever arm, so you can't discount the relo brackets as having no blame here. The LCA force for a given amount of traction decreases, just not as fast as the lever arm gets longer.
The only reason I can think of for...
I know you've got other suspension matters that need to get squared away first. A Watts link belongs well down on the priority list unless you yourself can identify a problem about the PHB that a Watts link is guaranteed to fix.
Norm
If the same code(s) returned, it points to the problem being upstream of the coil. Which could be anywhere from the harness connector to the coil to what the various sensors are telling the ECU.
You've got two cylinders misfiring, at least randomly and/or during startup, plus a high idle and...
:dunno: . . . bad fade sure doesn't say "pads are holding up great" to me.
If I were you, I'd treat 'Ring laps exactly like an abbreviated track day session, and be running pads and fluid rated for track use. Meaning high temperature DOT4 fluid, probably some supplemental front brake cooling...
I think they were tweaking how fast the SVIC migrated and how fast the anti-squat varied as the car's rear ride height varied. Any difference in the height from the ground to the chassis-side pivot would also be involved, and there's no reason to expect that this was left alone either.
Norm
Hope you're getting notices of reply to topic, as this section doesn't seem to be busy enough to encourage "just stopping by to see what's going on".
What I've got is for the other kind of track, but it does get street driven. Shown is the "track set". My "street set" is a little less extreme...
Hmmmm . . . yeah, the coincidences did seem too clear to be otherwise.
I doubt that just swapping a PHB out for a Watts link would be worth 2 seconds on a 2 minute lap either.
Norm
Can't tell for sure whether you're joking or if you know of a certain large thread elsewhere where the value of another kind of S197 chassis bracing was under discussion with the same 2 second lap time claim from having added it. (different vendor from either of the two so far in this thread...
Sometimes that's the right answer, sometimes it isn't. Just #becauseCorvette doesn't necessarily eliminate the tinkering . . .
Truth is, I've found it kind of fun trying to understand what's going on here, with suspensions in general, and in extracting more cornering & handling performance out...
No way to make this short . . .
Seems neither one of those articles ever mentions 'rear axle roll steer'. This is where the axle actually steers slightly as the body rolls. This is not the same effect described as the rear of the chassis moving sideways relative to the rear tire footprints...
SCGallo has basically described the PHB's geometric behavior as the rear suspension rises and squats - it really is minimal. OE PHB bushing compliance very likely involves greater lateral axle movement during cornering than the geometric arc can when you launch, shift, or brake hard.
There's...
They're peak g's. You could probably take average g's to be about 10% lower. My Aim Solo has measured as high as 1.36g when the tires were fresher.
Tires were (are) MPSS 285/35-18 on Forgestar 18x11 wheels (all four corners).
