Best alignment after installing crash bolts
 
I have read all the posts but don't see a definite consensus. Looking for individual recommendations for the best all around alignment after front OEM crash bolt installation on stock suspension. Daily driver only. I want reasonable straight line tracking and good tire wear but I understand the advantages of negative camber on the front. All opinions welcome.
Thanks in advance!

Anywhere from .8-1.2 degrees negative camber, without a drop i'm not sure how much you will be able to get but anything close to -1 is fine.

You aren't going to get enough camber out of the crash bolts to really make that much difference. I have -1.3/-1.2, I'm not worried about tire wear at all. I'm also using 1/32" toe out in the front and 1/32" toe in for the rear, which is also not very extreme.

I've run -2.1 deg camber on a previous DD and that was enough for me to wear the tires evenly. I agree with the above.

-1.2 camber and 1/32 toe out front + -1.7 camber and 0 toe rear.

Fun setup. The 0 toe out back lets the rear come alive a bit more compared to running a little toe in. Car's very neutral.

The most negative you can probably get in the front will be a bit over -1.0, maybe ending up at 1.2-1.3-1.4 depending on how much you weigh.

The rear is non adjustable camber, so you would like the front to be similar or more negative than the rear, so the max you get may be the best after all.

I will give my own opinion on the toe in.

You specifically said "reasonable straight line tracking", so I would do +1/32 or so toe-in for the front. The bumpsteer curves on these cars are pretty aggressive, so you don't need to cheat as much as previous cars.

Same goes for the rear, but if you can handle zero, I would, but I don't think I would recommend rear toe-out for anyone concerned about "reasonable straight line tracking".

Toe in kills the tires about 10x faster than camber, so place your priorities there. Try to have the car aligned with you sitting in it.


Ground Control


PS This is the caution with adjustments at the bottom of the strut: If you need the struts clamped at very different angles to keep the tires at the same camber, you may introduce other problems, so keep careful notes.
