tire wear
 

Hey guys,

I was at the track this weekend. I wanted to get some opinions on seasoned track day goers.

I noticed that my front tires had a lot of wear on tread just adjacent to the tire wall. like piece were chewed off. Nothing on my rear tires.

Do you guys think i am over driving or is this just normal for this car?

Thanks!!

Probably need more negative camber up front. What is your alignment?

What is your front camber?
What tire model?
What pressure were you running (specify if hot or cold psi).

What tires were you running? Sounds like they're chunking. You got any pics?

If your car is totally stock (suspension wise at least) and you were attempting to drive it at 10/10ths it's totally expected for this to happen. The car lacks enough camber up front due to the Macpherson strut design.

Find a way to add camber that suits you and get it aligned to reduce tire wear up front. As an added bonus you'll have a lot more front end grip in steady state cornering which should lead to a more balanced fun car imho.

Based on my limited experience I think -2.5 degrees would be a more aggressive compromise between track and street, -3.0 and you're getting close to evening out the wear. Less may be workable depending on what you want out of the car and your driving style and what you want to spend on modifying it for track use (camber bolts vs. camber plates vs. slotted struts).

Order the parts, schedule an alignment, swap the tires back to front and head out to your next track day! And keep an eye on the brakes if those are still stock too, those will be the next to go (if they haven't already)

FWIW I'm running -1.9 front camber, and I'm still getting some outside shoulder wear with autox days and sprited DD. Next summer I'll go for ~-2.3.

Thanks! Ya I am running fully stock suspension wise.

running continental extreme contact.

how much will camber bolts help?

If you're serious about tracking, I'd get camber plates right away. I went the bolt way (did it twice, one with crash bolt and another time with crash bolt on top and camber bolt at the bottom). Max I got was -2.4 with lowering springs (TRD) and it was STILL an understeering pig. Deduct -0.2 to -0.3 range since you are on stock springs.

Either you manage the tires (slow in, manage mid corner) or increase camber. I now have -3.2 and its JUST right based on tire temps.

Thats fair.

I just got into tracking the car this year. So i am still learning. I will eventually get coilovers and whatever I need to make things better. just wanted to make sure this is normal haha!

I want to increase my time on the track and get better lap times and slowly upgrade.

Get the lower position camber bolt and then put the lower bolt in the top hole for maximum camber on minimum budget, a good alignment shop should be able to max it out and understand what you want.

Like @lufty says, you're only going to get about -2.0 to -2.5 this way, it will help a noticeable amount but you will still see outer shoulder wear.

imo rotate the tires and keep driving hard, it's all part of learning

Edit: oh, and here's what my tires looked like after my second track day
