Yup as dallas said really.. spring rates need to be bumped up a couple. Ask dallas what rate he runs im around the same as him haha.

Toe out on the rear is a life changer also

 

This. I run more camber than that on NT01's..

 

Yup, I run min -3.4 front with NT01's.

 

i ran -3.4 on R7 and -3.8 on A7 to keep the outer edge of the tires from cording. and also flip the tires on the wheel when tires are half worn. you give up on braking grip but the tires will last longer.

 

I get bluing on the outter edges of my tires (they roll over perfectly to the triangle mark thingies). That means heat, due to not enough air in the tires? So I should increase pressure and reduce camber? Currently at 3.0 front and 2.0 rear.

 

Post a pic of the tire. My guess is not enough camber. You shouldn't really be touching the arrow. You should be wearing the tire to the edge of the tread that the arrow is pointing at.

 

No, that means you dont have enough camber and are heating primarily the outer edge. More camber and probably more pressure. But if youre bluing the outside edge, then mid corner the inside edges is going to be nice and frosty in comparison. Make that tire work more, get it happy in a corner.

And for those thinking 4deg of camber is going to dramatically effect your brakes compared to 3deg... no. Just no. Look at how much camber cars like DTM or world challenge run. Its a lot!

 

Im sure Dallas would be able to speak more eloquently in regards to this but when you're on the brakes you are loading up the front and on a mac strut front we lose camber with compression anyway.

 

That's where it rolls to. I assumed I'd want it going to where the arrow is actually pointing. Made the most sense to me.
As I'm typing this, I just went out to take pics... looks like the blue from Sonoma looks to be mostly gone, after this AX day. So weird. There is some wear on the arrows from this last event, from starting with too little air pressure. My chalk lines were spot on, after adding a couple PSI after.
I start pressures at 30psi front and 28 rear. Once warmed up, I chalk them and adjust accordingly. I don't have my notes as to what pressures were hot, but I usually end up bleeding about 2psi from each corner. For the last event, I started with the pressure I ran at Sonoma..not realizing the tires wouldn't get as hot at AX, which I assume is the reason the were rolling over too much during the first few laps.
For fun, here's a vid I made from the AX(ish) event at Buttonwillow. You can see my mystery smoke puffs are now coming through the exhaust, as well as from under the hood. I'm still trying to find time to get into/under the car to look around. Work has been kicking my ***. These shots were during fun/experimentation runs, so not my fastest or best driving. Ended up with a 55.07x which was good for FTD, about 2sec ahead of the 2nd place Atom.






wear on arrow from AM session start with too little pressure. Maybe still a hint of blue.

also a hint of blue.. kinda.

 

Not enough camber.

 

Yup, not enough camber for sure. -3 is just getting started

 

Here is mine for comparison. -3.4 and Thunderhill which is basically 80% left turns so the front right gets all the outside beating.

If I recall correctly, around 37 hot

 

I have gotten so much blue on my R7’s. Good to know why now. Hard to imagine i am not overworking the tires with more horsepower and faster times. I must be much smoother. Or slower and don’t know it.

I can’t get past a certain point in camber b/c my tires nick the springs.

 

More camber. Will do. I assume rear, too, since its doing the same?
Try -3.4 front and -??? rear?

 

Try flipping the eccentric at the knuckle to the arrow pointing in and then dial more neg camber up on your plates. Can also try fitting shorter springs or if you have fender clearance larger spacer/ lower offset wheel.

I generally go for around half what I run up front in the rear. Rear is tricky however as you can only dial in so much neg camber before toe can no longer be kept in check so keep that in mind. Somewhere around -1.8 to -2.0 depending on ride height seems to be around the max with still keeping toe happy.
