Evo X vs. Evo VIII and IX
I own an evo 8 GSR, evo 9 MR, and I owned a evo X gsr. I bought the evo X new and sold it after 20 months. I still have both the evo 8 and 9 and don't plan on selling them. I wanted to love my evo X the way I do the 8 and 9, but the additional mass really spoiled the fun. I wish the evo x was made 250-300lbs lighter. If it was, I would probably still own one.
Ct9a ftw... Everyone I know that traded or sold theirs for an X regrets it n wish they still had their ct9a. X's r just to heavy IMO!
Ct9a= great track car
Evo X= great DD
Owning both is the ultimate win tho. Just my opinion.

those CD lightning lap tests need to be taken with a huge grain of salt.. different days, conditions, drivers, tires, etc. i'm surprised the stock ix mustered what it did with totally neutered rear diff.
better to look at competitive racing, where those playing fields are leveled.. you'll see the X dominating rally, and the 8/9s dominating anything autox. track racing seems to be a toss up based on whos put more money in the car.
To each his own. I have an X, DD, and love it. The VIIIs and IXs are definitely more hardcore, but it's hard to find any that haven't been molested these days. All you VIII and IX guys enjoy your cars. They don't and WON'T make em like that anymore.
FYI not sure if I had posted this here: English Racing's made some pretty nice breakthroughs with the ACD tunes for 8/9s, which I'll be testing out extremely soon.
I still consider the evo 8/9 + acd tune + aftermarket rear diff the epitome of street driven evos, handling as they were intended, with honest, consistent performance. IMO mechanical rear diffs are just plain a must for seriously raced evos. Getting a car to handle how you want it can be achieved so many different ways - reliability and repeatability are priceless.
The only real knock on the older cars is lack of sawc/sayc, which can and should be upgraded, and the only real knock against the X is the weight, which can and should be upgraded

btw, does anyone have the Cd's and cda's of these cars?
i've found ~0.36 for the 9 and ~0.35 for the X, but the frontal area figures are all over the place. i assumed the X had larger frontal area, but perhaps not?

I heard .38 for the 9 according the Evo vs STI wind tunnel testing data that was published. They also had lift and rotational coefficients which you may find interesting. Otherwise I'm not sure about the X.
(If you search for Evo vs STI wind tunnel, you'll find the thread with scans of the published results)

hey now, i think the better question is why the 2010 x se destroyed the x mr by a full 2.9s

All 2010+ Evos dyno about 30whp higher than 2008s stock. The factory tune on the 2008s was really bad. The power difference is really noticeable behind the wheel as well.
How is this for compromise? I wanted an Evo IX. Couldn't find a decent one, so I looked at VIIIs. Most of them were trashed. So, I ended up buying a new Evo X in 2011. Ask me which one is best and I will tell you that I love all 3 of them.

Evo IX and Evo X.
Lately i've been contemplating getting a new Evo X and strictly using my IX as a fun/track car. I never considered it before as the X never really appealed to me but as of late a new car and the amenities a new X offers is enticing. It's also come a long way since it's initial debut and the fact that next year is the last year has also sold me on it. Everybody i've talked to told me not to let my IX go as it's difficult to find a good/clean one now a days. I also have friends that have bought both and ended up selling one or the other as two Evo's are very costly. I also fear neglecting my IX after getting the X.....
For those with both which do you enjoy more and which if you had to keep would you keep.

It's financially stupid however to have both.... Still thinking it over.
I'm in a similar situation as you right now. My IX is my weekend toy/track car. It gets driven one, maybe two days a week and on NASA track days. That being said I love my IX and don't ever plan on selling it. In recent months however I have been tossing around the idea of selling my current daily driver and picking up a X as my everyday car. I really like the X's, they are amazing cars but the IX is what still does it for me. IX's are getting more and more rare these days, especially in regards to really clean ones. I think thats why the value on them has been going up in recent months. X's have been produced for almost 7 years now so I don't think the value on them will hold as strong as the IX's. As for neglecting is concerned, I don't think I would neglect my IX if I got a X. The IX is such a visceral and exciting car to drive and I look forward to every weekend and track day when I get to drive it. Even if I got a X I would still look forward to driving IX on the weekends. My neighbor down the street and one of my good friends sold their IX's and got X's a while back. It was a living in the moment decision because now they both regret it and are both envious of my decision in not letting go of my IX. As far as cost of ownership goes I know our cars aren't cheap. Luckily I have been able to keep my cost relatively low by doing all maintanence myself, within reason of course. The X will be a learning curve for me because I haven't tinkered too much with that platform aside from helping my buddies work on theirs. At the end of the day though the IX is still my favorite Evo as well as my favorite car. Hypothetically I do get a X and at somepoint down the road I'm in a pinch and have to sell a car it would be the hands down be the X. My IX is special to me as I'm sure your IX is special to you. We take care of our cars and keep them clean and thats why I look forward to driving mine as much as I do. Whatever you decide to do, keep the IX. GL
Yeah, as my IX is now a dedicated track **** I've been lusting after a X for a daily. I've mostly talked myself out of it because I've realized I can't avoid getting into trouble with a fast car on the street, which is one of the primary reasons I have a track car in the first place. I've managed to avoid any tickets for years now (knocks on wood) by driving a 1997 Geo Prism crapbox daily.
