Camber recommendations
I'll be running my first track day of the season in May, and am looking for recommendations for camber settings.
My last outing I ran -0.6 front and -1.5 rear (both stock). I had quite a bit of rollover in front. The car handled okay, but could do better. Since then, I have upgraded struts (Tokico D-specs), springs (STI), rear swaybar (22mm adj.), all endlinks (metal), and added camber bolts. I can set camber at ~-1.8-0 and rear ~-1.5-0. I am thinking -1.5 front and -1.0 rear or maybe -1.0 front and -0.5 rear, but am looking for recommendations (with justification).

As much front negative camber as you can get. At least -2.5 degrees. -3 would be better with the amount of roll you'll have with those springs, swaybars, and a reasonably sticky tire. Then run -1 to -1.5 in the rear.

I wouldn't touch toe and leave it at/set it at 0. Only adjust toe on a track if you're having a problem with rotation after all your camber/caseter is set. Toe is the last thing to adjust.
You definitely need more camber in the front. -3 is a good target. --kC |

If he's going to the track I wouldn't suggest driving hard with straight up toe in the back anyway. A little toe in will keep the car planted in braking zones instead of dancing around. Im talking 1/16th to 1/8th

Dancing around in the rear can help with rotation

I don't think 0 degrees is going to be the cause of looping in the braking zone.
I always run zero degrees and have braking zones down hill at 145 mph at Road America into turn 5 and have no issues. The back does dance around a little but nothing that might cause looping. But then again I have never tried anything but zero all round. |

I'm just bench racing here as I have yet to track my wrx (only got it in November). When I read the first post originally I thought it was his first track day ever, but now with a re-read its just his first of the season.

Why good rotation won't do him any good if he keeps looping it in the braking zones?

i'm one for zero toe all around as well.. unless you are really seeking a specific dynamic that your car needs.
also with this being your first track event.. I just dont think you need to play with toe. |

0 rear toe (0 is still an adjustment tho...) Toe in will make him stable, but in an ideal world, one would align based on the track he's going to (develop a log every track day to keep notes in regrding what the car is doing for each given corner, or its general composure). The toe in can be beneficial at one track, and detrimental at another, slower tighter track. Whereas I think everyone can agree, rear toe out is bad on track unless there's something else one's trying to accomplish. --kC |
