The only correct sound track would be the car's exhaust note. Norm

Yes. Norm

Chances are that the flange is OK and its wobbling is due to the bearing issue. Unless the flange itself shows evidence of damage (unlikely). Norm

Have you ever noticed a little extra eagerness for your car to turn in when you get off of the brake pedal at the end of your trail braking? Same thing can occur in situations where you'd have been at 'maintenance throttle' in a turn that decreases its radius slightly, except that it's a much...

Stock weight, whatever that was. I've never got it weighed but I haven't made any changes that affected the weight by more than a few lbs or so. Roll steer is something that is always there, and whether it's understeerish or oversteerish depends on rear ride height as that affects both LCA...

220 lb/in They're the BMR GT500 Handling Springs (20 lb/in stiffer than BMR's non-GT500 rear springs). I got them as part of the #SP-072 kit but they are #SP-074 for the rears alone. They also dropped the rear of my car by about 1" vs the advertised 1.5", presumably due to the difference in...

The rear axle job is back on hold for a couple of days, so I decided to tackle one of the other little tasks. Some time ago I'd pulled part of the interior trim and carpeting up due to the water leak. Today I started putting that stuff back in. It took a while to figure out where the...

Loose or bad bump stops is all I can come up with. I can't see lateral axle migration under the heavy load being enough to be a significant contribution to either centering the stops on the chassis-side pads or moving them off the pads completely. Chances are you were riding on the rear bump...

The Ford Performance adjustable PHB ends measure 1.50" wide. The flanges on the supplied bushings are 0.20" (each) for a total width of 1.90". The supplied inner sleeves measure 1.85". For reference I measured about 1.88" for the OE PHB "sleeves", and the FP bar ends with bushings was a...

I should have asked this earlier - what size NT01s, and how wide are the wheels they're mounted on? This is more out of personal curiosity than any attempt to evaluate anything. 305/35-18s aren't exactly inexpensive, and 275/40-18 is a bit taller than I'd ever want to go (neither 275/35 nor...

Looks like damage from "road" debris. I'd be uneasy about that as well. For 20-ish heat cycles - is that 20 individual sessions, 20 track days, or something else (like 20 total mornings plus afternoons)? NT01s seem to get decent reviews regarding lifespan. They're not on Terry Fair's list...

Good deal. How many heat cycles are on them now? Are they getting close to cording? Norm

Less rear bar??? All else held constant, I'd expect a 245/305 amount of tire stagger to understeer resolutely, as in everywhere in a corner. Including turn-in (where more front bar/less rear bar can sometimes be of advantage). Norm

I really think you meant "understeer". Hopefully Hugh will pick up on this. Norm

Hoping to see some video. Norm

I hear you on the difficulty in using 2nd even with your higher redline than mine - that 2.10 in the wide ratio gearset is even shorter than the 2.00 in the TR3650 (and almost as far away from 3rd). My opinion - gear spacings much above 1.4 to 1 can be somewhat cumbersome on the downshift...

Is that a Delaware PCA event? Norm

I've never noticed that on my car. Then again, my car is sitting at OE ride height in these pictures and was something of an outlier in some other aspect of suspension. These are the best available pictures. 265/40-18 tires on 18x9.5 ET+45 GT500 wheels. My eyes can't see any difference...

Well, it looks like there will be some bushing shaving going on, and probably a washer shim or two at least at the chassis-side bracket. I did spend a little time thinking about the easiest way to check the sleeve to bracket gaps while everything was loosened or off, and it turned out that I...

I find I do a lot more thinking, which adds to the time required. Things like "how can I do this that will make it easier for me (or even possible)?". Getting a bigger torque wrench than strictly necessary to tighten brake caliper bracket fasteners down to 80 ft*lbs or more while potentially...

No shame in that. Most people don't get paid to do computer modeling of structural systems (where you need to be aware of element stiffnesses other than against pure tensile or compressive loading and maybe simple-beam bending). Being able to visualize 3-D arcs is another skill that either...

Don't feel bad; most people don't have any idea how the end connections for various links, arms, and bars really need to work. For most car enthusiasts, whether DIY'ers or those who go the shop-install route, the only thing on their mind is taking the fore-aft compliances out of the "soft OE...

I'll probably crawl under the Mustang sometime today to determine which way I'm going to go. Once I get enough ambition. Off-topic, but related to the slow progress on my Mustang mod . . . I spent significant time over the last three days upgrading the brakes on our WRX. Not due to wear...

When the poly is longer than the sleeve, there is a greater likelihood of squeaks (some or a lot of which come from the ends of the poly against the sides of the brackets) and clunks (under the combination of PHB loading in a corner plus suspension movement). Getting the poly away from the...

I ordered the second set (separate line item on the invoice, around $40 IIRC. But worth having in case it goes out of production. I'll most likely end up having to do a DIY mod (as installed, the poly is longer than the sleeve). I'll either trim the poly or add washers at the ends of the...
