Can I use this vague excuse with Gwen?

Buying a set of pics from the track photographer in Pittsburg. When I was looking at the prints I noticed the camber issue on my passenger side front tire.

Don't really know if this is normal or not. Contact patch is kind of pitiful. Driver side is awesome, but makes me kind of wonder if a full 2 degrees is too much for a tire that wide. If you look at the Mustang I'm passing his skinnies are flat on the road.

Pictures depict well the high camber, and low grip on the inside tire. I have to admit I was late passing the other car, so I was probably a little hot in the corner. It just doesn't seem to be optimum for what it is, thinking of making some changes up front.

First off Ron the turn in the pic cambers to the inside so that will magnify the air space at the outside of the inside tire. The only way to really know if your alignment is good is to check tire temps.
On the same note.....when I went from 275's to 295's I never changed my alignment settings and was dragging the inside of the inside tire. The steering felt heavy and I was scrubbing a lot of speed off in the corners. In addition the tires temps were hotter on the inside than they were on the outside.
I went from 1.7 to 1.3 for the next track day and it was like night and day. The split in temps between out side and inside of tire was only 2* with the outside being hotter.
Blew me away on how only .4 degrees in camber made such a huge difference.

Thanks G, I really do believe 2 degrees is way too much for my setup. Center of gravity is so low, and the car just runs so flat through the turns, I think I'll cut it back to 1.5 and see how it does. Funny how seeing pictures while really leaning on the car can help to confirm something though.

I really need to take this more seriously, stop running every lap I can, including the cool down. Come in early hit the tire temps quick, and stop just using track time as my personal stress therapy.

Sounds to me like you've got it figured out Ron.

No prob. It took me 3-4 years (probably a total of 12 track days at most) to finally get my car where I want it. I would do 3-4 laps a session then come in and make adjustments. In addition to changing parts (in between track days) at the track I was having to have to pull the jack out, lift the car, put it on jack stands and make shock, rear roll center, tire air pressure adjustments, etc, etc. What a pain. I think I learned a lot doing it though and(knock on wood)I finally got the car dialed in.(For me anyways)

Funny though, I always studied my on track pictures. This isn't a hobby, its a disease :lol:

It's at least worth a try, though I suspect you'll sacrifice more outside tire grip than you'll gain on the inside tire. Even as low as your car is, the inside front is still going to be pretty lightly loaded and can't gain all that much.


FWIW, that Mustang doesn't look like he's running nearly enough negative camber for that car, particularly with what I assume is still a strut suspension - I'm seeing camber that's slightly positive on his outside tire, and radial tires tend to actually grip best at a slightly negative camber Maybe he's running a mildly aggressive performance street setting. Terry Fair at Vorshlag has done lots of testing on the S197 chassis and has ended up using a serious amount of negative camber (somewhere well out past -3°, IIRC).


Norm

Those newer strut Mustangs do seem to work pretty well Norm. Funny how you figure it all on paper, cycle the suspension, try everything you can think of to get it right, but until you see the parts real world in action, your never sure what its going to do.

Killing time before I leave for OK, so I thought I'd post some pics from OMCC

Such a cool car Ron!! Have fun on Drag Week!!:trophy-1302:

That blue does photograph well. The guy driving has the perfect face for radio.
