Okay, I think 1/4 inch total toe is reasonable.
That's 0.28 deg each side, for my tires.

I talking about rear toe. I have no interest in 1/4 in of front toe on a daily driver.I'm at .21 each side right now in front.
I mean, it will turn quickly with the front toe out, I just don't want to drive every day at 55 while the front end plays games.
I tried playing with pressures on my tires (A052) and was able to get more grip out with lower pressures. Turn in wasn't affected too much, but I started to see noticeable wear after a few runs on the outside shoulder (even with -3.2 camber) after just a few runs so I bumped it back up. With the RE71 it might fare better with the stiffer sidewallFor me, the short story is I’ve increased the front rate from 400 to 425, raised the front ride height and decreased front rebound.
I think what you are alluding to when say make the front end happy, is to not overload the front tires.
This can also be done with higher front tire pressure, which I may test this weekend.
I entered this season woefully unaware of what slapping on 400 in/lb springs front and rear would do.
Thanks for continuing to push me to rethink my setup ideas and the underlying theories.
I'm considering higher front pressures to act as more spring, to keep the tire contact patch from being overloaded, in the same way that Jackrabbit suggested that we try higher front spring rates to make the front "happy".I tried playing with pressures on my tires (A052) and was able to get more grip out with lower pressures.

I'd recommend starting in 1/8" TOTAL increments. It will get loose in a hurry when you have gone too far- you'll know it when you get there (when it's too fast to catch)! At that point, back off 1/16" TOTAL increments until it's manageable.The post said to start at 1/4”, but don’t be afraid to go as much as 1/2” total toe.
Here's another in pdf formatHelpful link to convert toe from inches to degrees.

That makes sense. You'll also be decreasing the slip angle of the tire at higher pressures which could make the tire feel more edgy. Are you planning to use the pressure to test if you want to move to a higher springrate?I'm considering higher front pressures to act as more spring, to keep the tire contact patch from being overloaded, in the same way that Jackrabbit suggested that we try higher front spring rates to make the front "happy".
I typically run 37 front and 34 rear. I'll bleed down the rears as they heat up to add slip angle, helps the rear end move a bit. Right now I'm running 245/40-17 on 17x8.5Howdy,
What pressures were you running?
I've been using 36 front / 40 rear with 255 A052's on 18x9's.
I tend to be pretty insensitive to pressure changes, but still curious what others are using.
