my set up on 245 azenis( the old ones)

zero toe all around - max negative up front max positive in the rear which is about -1.5 and -.9

operating temp on the old azenis is around 98 and they usually need to be cooled after the second or third run even when it's below 80 degrees outside, so bring a spray bottle. 43psi up front and 37-38 rear gives a good temp gradient for asphalt.

edit- .1 deg toe in upfront .1 deg toe out in rear.. this helped dial out some mid corner/corner exit understeer

I drove Donnie's car at the 04/16/06 Autocross here in Denver...and these are my post-event notes...

* I'm still a Novice - I've been to 8 Events and 1 school.
* Because I was Donnie's Co-Driver, I ran with him in the local X (Experts) class. Having a car marked "179X(N)" isn't all that common...
* Had I not tagged one cone on my second run, I would have placed "not Dead Effin' Last" in X, which is my goal for the season.
* Even with my tagged cone, I bested the D-Stock cars by a full 5 seconds - and a full 7 and a quarter seconds if my fastest run were clean...
* My runs were a full 10-12 seconds faster than what I can manage in my dedicated autocross MR2, which is a light, nimble vehicle...
* Even in my noobness I was only about 3 seconds back from Donnie...
* I've seen the light and...
* I'm selling my '03 Vibe GT (DD) *and* '85 MR2 (Dedicated Autocrosser) and buying an '02 IS300, and modding to match what Donnie's done thus far...

Sometimes it *is* the car...

Yeap, those look like the numbers most everyone ran in the rear.
How did ya get -1.25 camber in the front?? I thought we could not get more than -1.0 camber in the front?

shocks?

I'm considering purchasing an IS300, trading in my mazdaspeed protege. One thing that gives me pause is the soft and more disconnected feeling of the suspension. I love how tight the msp is. Will a good set of autocross shocks and a bar get me there? How dramatic is the difference? How much will they cost?

Thanks in advance. =]

You won't be disappointed!

The IS comes alive with sways alone. Of course, modding being what it is, you'll likely want to go to shocks and springs too. I just finished that journey myself. Started with sways, loved it. Put Koni's on, loved it more. Put Eibach's on, love it even more!

I haven't autocrossed it yet but have been to the track. In all honesty, you'll probably want at least sways and shocks for the track.

So to alignment, has anyone experimented on track as opposed to autocross? I'm hearing that close to maximum negative camber is good at the front, half way at the back, and if anything, a little bit of toe out at the front and neutral at the back. A lot of positive castor seems the way to go here to maximize negative camber under cornering.

I understand that autocross setups could be poorly suited to track use, especially high speed tracks, as they can be VERY unstable.

I had the chance to measure temps across the tire at Laguna Seca a while back. The suspension was at the factory settings, and the car had only the TRD sways at the time. The temps at about 38 psi (cold) in front and 34 psi (cold) in back were pretty even across the tire. The hot pressures were about 45 psi in front and 40 in back.

Does anyone have any input as to racing specs?

I have attached a short article on the subject too.

New to the IS 300 and need advice

autocross a miata and want my IS 300 more for high speed stuff ( hwy and posible track days).

I found this email string which seems to end a long time ago but addresses alignment settings for autocross.

I am looking for assistance with recommendations for what to set the car for higher speeds than on an autocross.

Also recommendations on aftermarket additions that will help the car.

I am used to using:: revalved for autocross Koni yellows , larger front sway bar, Hawk pads,LSD and -1.2 negative camber front[ max i can get], -1.5 in rear to reduce power understeer....small amount of toe out front and same small amont toe in in rear for straight line stability with max caster. works great on a 99 miata but the IS 300 is significantly different and would like to hear from those of you that have learned all the tricks to make this car handle beyond the factory's expectations.

thanks for you help.

What class are you running with those sized tires?
