But yes, car is if anything more of a track car than auto x. My alignment specs are -2.5 and -1.8 I believe.
FWIW, this is on an auto x car. You might just need to adjust your alignment.
I was on 10k/14k springs, restacked rear diff, RS front diff and my car was very loose. 275/35/18 NT01
Base alignment:
-2.5 camber up front
-1.5* in the back
Zero toe all around
It understeered until I cranked the front camber negative (which would also push it toe in). It was around -4* where it was very loose, tire wear was saying it was too much though.
-3.5 or so seemed like where it needed to be in the front and maybe a bit higher on the rear.

Check out this thread https://www.evolutionm.net/forums/ev...y-factory.html . Apparently Mitsu messed around with the rear diff to reduce warranty work but this can be corrected for a better working rear diff. If you dont upgrade it to a 12 plate setup as others in the thread have then the mod is basically free.
The alignment is where I would start. Getting the camber up makes a massive difference. There is a balance between camber and tire pressure to get good tire temps and within that balance there is an ideal match that provides the most grip.
Not running at the ideal point gives up overall grip but it can be used to balance out the car without having to change hard parts.

Dont most people agree on the pressure that specific tires should run?
How big of jump us it from incorrect plate alignment to correct alignment to the 12 plate?
Will you still need heavier spring rates in the rear after those mods? What about with a bigger rear sway bar?

Im actually in the hunt for coilovers and Fortune Auto's 500 series seemed quite tempting for the money. Also looking at D2 and Tein.. Budget is up to $1250.. any suggestions on the F.A.'s you'd care to share ??

By the way where do you track? One thing to consider is track layout and road track vs. auto-x.
While I've driven on none of the c/o's you mentioned, based on reputation alone I would go with the FA's without a doubt.
