Ah gotcha and explains a lot. All that toe in is helping stabilize the rear along with the rear bias on the camber. If you decrease the rear toe a lot and dial in more front camber, the car is going to be REALLY tail happy without a front bar. Maybe go .40 toe and -1.5 front and -3.0 rear until you can get a front bar, then reel all the toe back out and increase the front camber to -2.0 or more depending on the bar you get.

What currently dont you like about the handling?

I think what I'm going to end up trying is 1.5 for the front camber and either keep the rear at 3.0 and bring it out to 2.5, zero toe on the front and just keep my rear toe within the specs that my machine suggests.

I didn't really have any complaints with how it handled before but what bothered me is my specs were uneven from side to side. I have noticed before if I was taking a hard corner and hit a bump it would un settle the rear and get twitchy. But I feel like that can be solved with adjusting the dampening on my coilovers.

A rear bump steer kit will make a night and day difference when cornering and hitting bumps or uneven surfaces. It will completely eliminate the twitchy and unsettling it may cause. I'd say do .20 toe per side in the rear, total .40 If you get the bump steer kit go with .15per side .30 total. You will definitely need to max the front camber. What tires are you going with? If you go with rs3s go with 5.9to6.2 caster

I'm running the same tires I had before. Bridgestone potenza re760 sport. Would the .40 rear toe be conservative enough to not chew though my tires excessively fast?

I've tried everything under the sun, -3 degrees is too much at the rear, you shouldn't run any more than ~ -2.5 keep toe around .40 degrees total in the rear AP1's need more toe than AP2 because AP1 rear upper control arm bushings are smaller and deflect more under load than the beefier AP2 ones. Also try a hair of toe in or positive toe as it helps mid corner grip. Try .05 toe in up front. Caster is fine, you can go up to 8.0 degrees before the wheel starts giving you a shimmy. As far as front camber, if you have a super sticky summer tire, then yes you can and should be running ~ -2.8 degrees in the front, on regular DD tires I'd probably knock that down to an even -2. The grippier the tires the more extreme angles you need.

^thanks a lot for the info. I should be doing my alignment at the end of the day and I'll post what specs I end up with
