Yes, you still would. No matter if it is directional or non-directional or what way the tread on the tire points, to get the inside edge to the outside you have to take it off the rim and flip it. Moving it from the right to the left will reverse the tread pattern but will not move the inside edge to the outside edge.

My muellerized settings for MAX street was -2.5 front -1.8 rear. he told if I wanted to go race -3 front -2.3 rear. I have 0 toe front and .10 toe in rear which is the limits for toe out of the specs in alignment machine.

Nice pal. Lets see, I have 8 years of road racing experience in the SCCA, two track records, voted driver of the year by my region twice, currently am the assistant chief driving instructor for NASA. I'm using the Tanabe GF 210s for springs. Don't remember your other questions, but I think I have some what of a clue of what I'm talking about. What are your driving credentials?

On a well set-up car, a decent amount of camber will wear the tires evenly.

sounds like you can drive, but the issue here is STREETING A CAR, AND THE CAMBER LIMIT.

If you're running SCCA or organized racing, you're not streeting the car. Experience nulled.

edit: No attitude meant, but it sounds like your experience is exactly contrary to what was originally asked.

bbenavitz, GTWORX.com and WarmPepsi, you guys are all correct. But you guys are arguing from different perspectives. The EVO has inverted Macphearson struts which gains little to no camber when they are compressed, unlike suspensions using double A-arms and leaf springs. A lot of auto-x driver turn up the spring rates and lower their front camber. The reason being when the spring rates are really high there is very little body roll which leads to less -ve camber being needed to maintain a high contact patch during cornering.
But the EVO gains little camber as it get corners unlike Hondas and it is a pretty tall car with a relatively high CG, therefore there is need for more -ve camber in the front. Also don't forget EVOs are AWD which means when it comes to acceleration we are NOT traction limited like the FF or RWD cars. Braking is a different story .... I guess camber ultimately depends on how high of a spring rate one is running ...
The issue here is most want a streetable race race, thus spring rates are compromised.
Let's get back to topic ...

yes. I will say after 2 days at homestead, i'll agree with the idea of braking being compromised. I'd say i only have say 75-80% of the straight line braking that i could do before. I used to be able to hammer the brakes and then get off, but with so much camber, the car is a bit more squirly on track at speed.

...let the fun continue

Relax a little buddy....it was just a suggestion. Give it a try, many people run -1.5 to -2.5 camber with 0 toe and have no issues with inner tire wear.


And I'm more of an engineer anyway.....Chad on the other hand said the same thing as me....check out his driving "credentials"

you wont see marginally increased tire wear from camber.. .althought i totally agree that 3.5 degrees is too much...

toe is what MAJORLY affects tire wear...

You are right. I thought the dude at Works was referring to my habits on the track. I would never think that someone would make a comment of "your not driving hard enough on the street, have too stiff a spring or too much toe out".

Like most who track their car and use it as an everyday driver I don't throw on an aggressive alignment just for the track and change it back for the street as this is way too much hassle. I have tried on two others cars plus the evo to run 1.5 to 2 degrees of camber so that I would have a very good track car and hope that it would live on the street, but my "personal" experience is that more than one degree of neg camber with zero toe is as much as I can have that will not wear the inside of the tire after about 5,000 miles of driving including three or four track sessions. Don't ask me why others on this forum can run 2 to 3 degrees of neg camber and not get inside wear. I can't explain it, but I stand on my experience and opinion.

because the toe is adjusted for that. If you crank up the camber at the track, you're playing with the toe very badly.

I apologize...I think my first comment may not have come out as I intended it to.


And we are GTWorx (parent company is Racecomp Engineering), and are located on the east coast. Works is west coast. No affiliation.
