Default Alignment tomorrow - Input?

So I have an alignment scheduled tomorrow. I just put on Tokico Illuminas and (old style) FM springs with an old 17/16ths JR front bar (stock rear).

Primary use is street with about an autocross per month.

Here's what I'm considering. I'm interested in any thoughts on this setup.


Camber: -1.8* front and rear

Caster: 5* or thereabouts (power steering)

Front toe: 1/32 out each side - 1/16 total

Rear toe: 1/32 in each side - 1/16 total

Discuss....

Most aggressive street alignment specs I've seen have less camber in front than in the rear, by about 0.5*. I'm running -1.2 front and -1.7 rear. Haven't run equal f/r camber yet so I can't comment on how that would feel.

Caster and rear toe look good, but for a mostly street/DD car I would not run toe out in front. It makes the car a bit lively on the highway for my taste. Toe-in in the front will add stability but hamper straight line acceleration just a bit. As kind of a compromise between good road manners and flickability, you could have it aligned for zero toe, and then when you get to an autocross, just turn the appropriate nut (marked with a paint pen for reference) to give you some toe-out for the event, and set it back when you're done.

I run similar with a little extra neg camber in the back. It was initially setup for autocross hence the toe/quick turn in. A little twitchy at speed but manageable. I'd definitely run more neg in the back than front to minimize lift-throttle oversteer etc.

My 96 has -1 in front and -1.5 in rear with 1/16 out in front and 1/16 in in the rear. That worked fine until I installed a roll bar and then that setup was all understeer on an autox course.

The 95 is not a DD. It's my toy. I try to keep it nice and it IS primarily a street driven car but I plan to do a couple HPDEs next year (my girlfriend is suddenly interested in that!). I DO take it on occasional trips of several hundred miles but only 2-3 times a year. It's mostly a nice weather fun car that lives in the garage when the weather turns bad. I work downtown so it rarely goes to work with me. I used to DD my 96 and the dings tell the tale.

I was thinking of experimenting with equal camber after reading Emilio's take on it. I'm not road-racing the car so I'm not inclined towards a front bias. I just wondered if anyone else was running something similar and how it was working out for them.

So you think these specs will lead to trailing-throttle oversteer? I'm not real keen on that. I'm looking for quick turn in, balanced handling with MAYBE just a bit of throttle induced oversteer.

I like the thought of 0 toe and adjusting out for autox. I've never done that, difficult?
