I just had my RX8 lowered with Progress Tech springs (-1.2" & 205 Lbs./In Front, -0.8" & 145Lbs./In Rear) and still temporarily on stock shocks and sways. Tires are Kumho Ecsta XS' . I still need to get an alignment, but i am not sure what specs I should go for. I do not have to put daily driving, rain, or winter into consideration for my RX8 (hence the reason I will not look into stock alignment specs), but I will be going to my first Autocross session this month. I also plan on going to a few more other AutoX sessions and one track day at Lime Rock this summer.

If you guys can give me a foundation alignment spec to base future post track time fine tuning off of, that would be greatly appreciated. I will be going for my much needed alignment within a few days from now.

it kind of depends on your tires too but im using

-2 front, 0 toe
-1.7 rear, slight toe in

my car is a daily that sees track duty a couple of times a year, so far its been pretty good
reason for having less rear camber is it makes the rear slightly more loose, you may want to have even camber all round as a baseline

I was giving a guess of around -1.5 camber front with 0 toe, -1 camber rear with stock spec toe in.

Heck... it depends on many factors such as what tire you're running and if it's just an autocross car. If it was a dedicated autocross car running on fat Hoosiers I'd run at least 3 degrees negative up front (if you can get that much without offset bushings) and about 2.5 in the rear. And a little bit toe out in the front to help turn in.

As stated in the first post, I am running Kumho Ecsta XS' (extreme summers). I have no intention of running anything else yet. This is my weekend car and rarely do I use it for commutes, and when it do, the weather is always dry. I am going to Autocross my RX-8 this season for the first time. I am not Autocrossing with competition in mind, but more for seat time and getting the most out of my RX-8 with my set up. Hence the reason I would like to have a more aggressive alignment as opposed to stock (which still has me wondering for the estimated numbers), and as I learn the car, I can build upon the alignment settings and suspension upgrades in addition to my Progress Tech springs.
