Holy Camber
#26
rear won't go any "lower" i.e. any closer to 0.
the rear tires are worn worse than the fronts with less camber and toe in :headscratch: (I really think they got a good scrubbing on that road trip with all the weight in the trunk and back seats)
NOTE REMEMBER These have been Fliped

Power!!
Too many people giving advice and Team thinks half of them are wrong.
I'm interested to hear the outcome of your new alignment/tire choice. As soon as I get off my *** and get new springs I'm going to adjust my alignment to something along the lines of -1.5 0 -2.0 in front and -1/2 less camber in back for track day driving. Good to know that toe is the big tire eater over camber.

Based on the photos, your new outside edge (was inside) is very, very close to the top cap ply/ under tread layer. This layer, just below the normal tread compound is MUCH harder than the rubber above it. As Miles indicated earlier, be very careful when driving/cornering in the wet, the break-a-way will likely be very sudden and difficult to "catch".
I agree with you, the long trip with mega camber gain in the rear, due to the extra weight, likely accelerated the inside edge wear. The inside 25% of the contact patch was carrying the load which increased the tire temp in this portion of the tire. Inflating to the max inflation PSI would have helped, but not solved the issue. We often see this pattern on 911's etc.

We'll least its cool that I can say I have 911 style wear
I did 36 psi for the road trip
Hey Team do you see that 2mm wide little strip of rubber right on the now outside edge of tire. You can distinguish it by its lighter color in the photos. That's actually a little "mountain" on the edge of the tire wasn't getting worn as quickly as whats closer to the center of the tire. If I had to illustrate it, it looks something like this:
_______/\
(tire) (edge)
Any idea why this occurred while on in the previous configuration ?

I bought an inclinometer and do my own alignments...and I pull most of the camber out for even wear when not doing anything track related...
That mountain might just be the sidewall is stiff as hell...what kind of tires do you have?

There was once this stripper who shoved her toe in my friends mouth...he tried to say no...but it came out..."moe"...in those cases...proper enunciation is key...

You can't tell by the foot print? They're Advan Ad07s 265/35 on 9.5'' all around.
Guys I'm keeping the toe. There's absolutely no reason not too, the wear is pretty acceptable, this set of tires will last 12k with the flip and would have gone to 15k+ if not for that heavyweight roadtrip. That's very acceptable for AD07s that see autocross days.
Sayings like "say no to toe" are usually used to refer to ricers running disgusting amounts for looks. Read what I'm saying I have no way of keeping the rear end in check with 9.5s and 265s on corner exits, here check out this video and you can see how bad the situation was before a little toe IN in the rear:

Toward the end there is a compilation of 4 runs during that day of auto-x where there rear end would not grip under a high speed sweeping left.
If its impossible for me to decrease the negative camber in the rear below -2.0 making the front less negative then the rear would kinda be counter to what all the "cooks" say to use for alignment specs.

I'm too lazy to do homework...I'd rather take the path of least resistance in this situations and simply ask instead of relying on my craptacular memory...
That said...toe is good for other cars that need it...this car does not...its probably just my misguided self-made opinion...but this car really does not need toe as much as a good alignment and setup of the system as a whole...which varies from track to track and situation to situation...but overall toe = blah...
Get yourself a DIY alignment kit...and then start mucking with your settings...your car is going to behave a certain way due to the setup...easier to figure it out for yourself than ask for others to tell you...
PS: I found when I went over -2 on camber, softening up the sway regained the traction I was looking for...your mileage may vary...but stiffer is not always better in some situations...

Where is everyone getting their camber adjusted at? Is it possible to do this yourself or do you have to take it into a shop? I want to adjust my camber before my next track outing. If it's possible to do yourself, can you point me in the right direction.
thankx....

But from what I heard...I think firestone or someone like that has a deal where you can pay one price for alignments...and then follow ups are like $20 bucks...

Our cars dont need camber kits...you bought a sports car...all you need is the alignment tools to adjust it properly...you are looking for the tools to perform the alignment...not parts for the car...
