so this is my front left tire and i like to go on onramps a lot haha . i put that spot of white shoe cleaner so i can see how much of the sidewall touches the ground and it sure does touch a lot. i should be rotating tires soon haha. the other tires arent as bad. anyone else have this kind of wear? i wonder if increasing my psi on the tires a bit would be better?

 

get camber plates. The stock setting is just too vertical. You think that's bad? In ONE WEEKEND at Infineon I trashed a set of pretty new Goodyear F1 GS3Ds. My first mod was camber plates.

ohh if i lower my car on h&r's wont that put a little bit of camber on it?

 

not with mcpheason.

Try more tire pressure..get them up to 42 cold.

also learn to take a corner smoother, your tires should never roll the sidewall.

 

ohh yeah on the onramps can i get it smooth but the tires squeel. im going

about 52mph on it. i think it must be the hard right turns im taking which are

sharp. i was thinking of bringing up the psi a bit but i was thinking that it

wouldnt be so good for less intense corning or am i wrong? like the tires wont

have any give when turning. i read an article about how you put the shoe

whitener on the tire so see how much of the tire meets the ground. and your

supose to adjust your pressure so that it almost touches the sidewall but

doesnt touch. it seems that only my left front tire touches rolls onto the

sidewall. ill try putting it at 42 when i rotate my tires.

 

and the lean in the car will make the wheel have no or positive camber. Mac struts have almost no camber gain, maybe 1 degree tops. You're not the first to have had this issue, and trust me when I say that the cost of the camber plates will be more than made up for by longer tire life.

I used to get ~12k on a set of tires, now it's well over 20k.

does positive camber mean the top of the tire leans away from the car? so the camber plates would make it have negative camber and increase tire life?

 

but it's driving style and location dependant. So if you do tons of freeway driving, you will get wear on the inside tread due to neg camber and driving on flat stuff. If you turn a lot, then the dynamics of the car will get the outer front to have better contact patch managment when the weight is all on the outside tires, giving better wear.

I live in hills, and with stock camber, I was wearing the outer edge pretty fast. With -2 deg camber, now I get pretty even wear. But someone else who does a lot of freeway communing gets wear on the inside with about the same camber setting. There is no best, there's just the best compramise for you and your driving style.

Matt is right on the dot on this one. Negative camber with proper setting of toe and caster actually helps the tire wear. Part of the tire wear on the outter edge can be from over driven the car in corner and unproper inflated tire.

My MCS has Ireland engineering fixed camber plate with about -1.2 (-1.3 after alignment) in the front and M3 ZCP, I had -2.0 in the front. Tires wear evenly throughout on either cars.

From the picture, I can assume that you take your corner pretty hard. Without proper front camber and overinflated tire, you front tire will lean toward the outside edge in the direction of cornering. However, with negative camber, the contact patch at the bottom of tire will flatten out (more surface area) and gives better wear.

Good luck..

 

i have that prob in mine. im showing cords on the front outside after 5400 miles

 

Wha....??? Do you drive this thing 100% around cloverleafs, or what? That's crazy-fast wear. Either something is seriously wrong with your alignment, or every day is track day for you.

ohh interesting i think im gonna leave the camber alone since i do drive a lot of freeway.

 

go by a performance alignement shop and have one of the guys (or gals) read your tire wear. They'll let you know if your pressure is good, toe and the like. Then you'll know if your mix of driving style is a good match for how your car is set up.
