sorry to hijack a threat but its funny after rebuilding my suspension with TCP coilovers power rack etc my car goes around corners great but it does wander or want to follow road variations. I thought it was just wider tires. would one of those kits help with that.
heres the specs the car was last aligned at:
Left front Right front
Camber Camber
-0.03 .-.03
Caster Caster
2.7 3.1
Toe Toe
..03 0.01
Total Toe
0.04
Steer ahead
0.01
Left Rear Right Rear
camber camber
-0.5 -0.04
Toe Toe
-0.031 0.03
Total Toe
-0.28
Thrust angle
-0.17

If you have bumpsteer, it is most noticed over large dips and bumps and with soft suspension. Stiffer suspension doesn't allow the arcs of the tie-rods and lower control arms to compete as much, so doesn't alter toe. What you are describing over rough, rutted or uneven roads is probably tramlining, the tires wanting to follow competing road surfaces, giving the sensation of a self-steering car.
One of the drawbacks of wider tires is that the car will often be prone to tramlining. This isn't just in our Mustangs, but in most cars with wider tires like Porsche 911, BWM M3 and other performance cars (google "tramline" if you want an interesting read). Suspension design improvements can help as well as tire tread styles (some tires tramline much worse than others of the same width/bias), but good looks have some drawbacks. I know the handling is much better since I went to 225/45R17 fronts and 235/45R17 rears from the 195/75R14 tires all around, but my car tramlines terribly (you sort of get used to it) on winter-killed roads around here even with the same alignment specs and same offset wheels. With the skinny tires high bias tires, I had no issues. I wouldn't go back, though.

Part of it might be the road you are driving on.
My wife's Toyota Rumion (google search that one!) tracks straight as an arrow on asphalt but you put it on a concrete freeway and it tramlines like you're on the tow rope at a ski resort.

yea im thinking its the roads around here, we got pounded last winter with snow.. we got a lot of small batches of snow forcing the cities to put down tons of salt. the suspension is pretty taught as well. I could readjust the TCP front softer but i like the taught feel going through the corners. I have mideye 200lb maier race leafs in the rear with koni shocks. after a talk with mike maier im gonna ditch the konis for a set of bielsteins pretty soon.
here in ohio we do have a few big potholes LOL .... this road closure has made what was a 3 mile drive to the next city a 6 mile drive.

I definitely hear you about the car darting around and everything, I've been dealing with that since I got the car several years ago. But it became undriveable last fall, I just didn't feel safe driving it, now I know something else is failing in my suspension causing it to get to that point. But I've got the grab a track suspension with 620 1" lowering springs, and the negative wedge kit and uca lowering and 17x8 wheels, and it's always been a chore keeping the thing in one lane. But seeing this thread I think has finally gotten me pointed in the right direction.
Does anyone know of a more cost effective solution than the pro motorsports kit at $260? It seems a little high for the few little pieces of machined parts in the kit. Does the TCP bump steer kit provide the same effectiveness? Pro's and cons one vs the other?

Definately keep the wheel combo you've got!
Looks awesome!Similar threads
