So you are good w/ no spacers/extended studs in the rear? If so, that is awesome. I haven't bought wheels yet (I'm waiting to see whether the STU rules pass since I am not running the Evo at anything this year) but it seems like the extra $ on the Weds, compared to the RPF1s, might be worth it if it means not needing longer studs.

Wow, what a past couple of weeks. So 2 weekends ago I received what I thought were my front JRZ's. I took Friday off to get them installed and hopefully have her ready for that weekend to autocross locally. To make a long story short, I received someone else's JRZ's! Beyond frustrating to me, but it is what it is. I did get to autocross my buddies 997.2 GT3 and then a Corvette C6Z06 that weekend, so all was not lost.
I did receive my coilovers about 2 days ago and got them installed yesterday. I just need to get an alignment done here and let the testing begin!
EDIT: I did also finally get a chance to autocross an Evo 10 - MR. This was basic bolt on car, on Ohlins, 275 RE71R tires making in the 360whp range. Wow, the amount of rotation that rear has compared to say, the 8/9's I've driven is eye opening. I still can't get over how easy it was to get that car pointed where you wanted to, pretty much on command. I know it was mentioned before, but I would love to see what a Evo 10 could do in STU... Seems more than capable (granted this one wasn't a STU built car, just built for NASA rules).
I did 2 back to back runs. I must say, I'm not a fan of that transmission. I didn't do any sort of launching with it and I noticed on my 2nd run, you'd REALLY have to get on the gas early to get that transmission to "respond" else you will simply be slow in that thing. I'd love to drive a manual Evo 10 instead at some point, but beggars can't be choosers.

A manual EvoX I think can get it done in STU, as Talha (Forget his board name here) showed two years ago being fastest on day two when it was dry.
I havent dug enough into why the EvoX seems to rotate more for people beyond AYC but rotation really isnt that hard to get. Just make the rear do more work . Certainly gets tricky when you want rotation in some areas and stability or slight push in others. That's where the AYC probably shines.

It just feels different than any other Evo 8/9 I've ever driven, and I've driven/autocrossed countless numbers of them, among the vast array of coilovers/setups I've tried on my own. It reminds me much of a stockish NB/NC miata in ways, with how easy the rear rotates on entry and midcorner. Not necessarily on exit so much (at least from the limited amount of time I got) Granted, this Evo X was on the Ohlins off the shelf rates, so it definitely felt soft. But my mind has been opened.

I had to dig but found this old post about the X
https://www.evolutionm.net/forums/mo...l#post11425688
I assume it's a fancy-diff thing, but I dunno.

I stumbled onto this as I was hanging out at CBRD this weekend. It's a Best Motoring comparison between the IX and the X on a very tight track. (Keep in mind, I don't know what the exact model options are on these cars, what tires, ACD, AYC, SAWC, etc because I do not speak Japanese ) Start at 49:48.
Best Motoring 2008 01New WRX STI ImprezaLexus IS F Skyline370GT EVO X - YouTube
You can hear "understeer" when he is driving the IX Some words translate very well.
IX: 23.0
X 5MT asc off JV-= off: 22.4
X 5MT asc off JV-= on: 22.1
Any idea what the JV-= is?
Anyway I was just really surprised that in a course designed to punish understeer, that the X was so much faster. I guess the magic computers work pretty well.

I've driven both STU Evo 8 s and STU-ish EVO Xs. I did notice the Evo X rotates really nicely mid corner and on corner exit, thanks to S-AYC. It's comes in very handy in a sweeper. However I don't like the Evo X in slaloms because of S-AYC. S-AYC would cause the car that initiated a turn to keep turning and it seems the S-AYC system would get confused during quick direction changes and would try to keep the car turning when you are trying to reverse direction. That being said, I wonder if that could be fixed with a diff ECU flash. Has anyone looked at the new STU rules proposal? Proposal #28321. I'm liking what I'm seeing for the most part, the only thing I would change would be the tire size recommendations.
STU (AWD & RWD forced induction)..................................................295 STU
(RWD N/A & FWD).................................................................285 315
be changed to:
STU (AWD, & RWD mid-engine/ rear-engine)...................275
(RWD forced induction) ..................................................285
(RWD N/A & FWD)................................................................295
I think the Porsche Caymen would be too much of an overdog if allowed to run 315 wide tires. Plus I think the Evo X will actually become a competetive car in STU with 275 wide tires.

I have a co driver in my evo, else I would have considered it!
I definitely agree with the X and the slaloms. I would love to have had more time in it to truly get a better grasp of its handling characteristics!

You can fit 295’s on the Evo X. It will absolutely be very competitive.
I ran against a properly built cayman in my region in 2018 when I had my STU X. The owner also hired local hot shoe, national champ to help build and tune the car. They never gave me any problems and I was not too impressed with their car.
