having a upgraded rear diff allow CT9As to rotate a lot better and it's only a $400 part (TRE)

don't get me wrong, i like the X, but its just not for me. to most people, CT9As are tinny and cheap, but to me, its raw and direct, so i guess it's different strokes for different folks

p.s i have 4 friends with modded Xs so i've driven more than a few of them. there is no doubt the X is a more livable daily driver, but as a drivers car, i still like my crappy RS more

 

i'm sticking with my 9

 

Not to be a Top gear nerd or anything, but Clarkson said this

 

It still won't make the car rotate like yaw control will.

 

The only way I would buy an X is if I could keep my VIII. +1 for keeping the IX.

 

not to rehash this one, but how wouldn't it when even the gates car upgraded to cusco and tuned acd and turned OFF yaw control and got MORE oversteer? and said that the cusco oversteers more than the oem ayc? wouldn't the gap of improvement be even bigger between the cusco and the oem ix rear diff? esp since the actual differential part is EXACTLY the same

doesnt that say to you that a beefy mechanical can force the car to rotate as much as the ayc? or i could be missing something and definitely please explain. in any case, if the diff is enough to turn the car completely 180deg, which it is - that's enough oversteer for me - the rest is just throttle modulation. more oversteer beyond that isnt better - its worse

 

I went from a IX MR to an X and all I can say is that I wish that I could have both cars. The IX has personality like no other car that I have ever driven in my life. It's just like that GF that was no good for you but you had to let her go lol.. The X is a bit more refined but comes a live with few mods. When driving my X I always say, "Damn I miss my IX," but at the same time, I wouldn't really go back.

I know... not much help with the decision making process so I'll put it this way. If the X SSL package didn't exist, I probably would have never bought another Evo. It just give ME that little bit of refinement I was looking for and still has Evo blood running through its veins...

Both cars are amazing. If you can, keep the IX and pick up a X. That would be AWESOME!

 

id stick with the 9 it has the mivec head all u really need is a five speed tranny and your set...best evo ever made

 

WHAT AN AMAZING F*CKING GROUP OF CARS!!!

 

Really dude?

 

Really.....

 

I'll stick w/ VIII...
I had IX and driven modded X many times. Just too way linear power deliver for me. It just took the fun out of rushing sensation of forced induction.

For me, it feels like riding a sports bike when I'm in my VIII with the sensation of racing versus too refined and insulated IX or X. And, the X was way too heavy for me. Really, there's no comparison.

 

Well thank you for all your imput but I have settled with my decision. I'm keeping the IXMR and my wife is getting the X MR I get to enjoy both but the only problem is fighting who gets to use the X as the DD haha.

 

You're talking to 1 in 10,000 Evo owners, kyooch, literally. A car of that level of parts, weight reduction, build, and tune is beyond the scope and purpose of almost everyone that isn't campaigning a full time attack car that has no business on the street.

The USA CT9A guys are the only ones that think SAYC sucks, because they are trying to justify their cars. None of the other CT9A guys overseas got neutered of their AYC. You can dislike it all you want, but you need to drive it in many situations to understand. 99%+ of the CT9As on the road in the USA understeer more than their CZ4A brethren. 400HP and down (most Evo owners), the AYC helps laptimes vs. not having it.

YMMV with a trackstar special, but that's not what most all of us have.

 

My simple assumption was that if a cusco mechanical creates more oversteer for the gates car it would do the same for a closer to stock X, which you're right could be false. I'm really not saying SAYC sucks or anything even close to that - the problem is that most X owners think SAYC can't be outperformed by any sort of aftermarket mechanical set up (on tarmac), which doesn't seem to be true.
Regardless, my point still holds - if the mechanical can create enough oversteer to turn the car around 180, it has enough oversteer - the rest is excess and throttle modulation.

The benefit of the AYC IMO is more in regards to the nature of the torque distribution - ie, something that just locks immediately isn't going to perform as well as something calculated and programmed to lock more or less under certain inputs in a given situation. Even with that though, the differences are near negligible when you consider these are both turboed 4wd cars that arguably aren't as dependent on finesse of throttle control. There are also mechanical solutions to introducing gradual/increasing lock, like the cusco and it's springs in the diff.

I'm not saying AYC doesn't help.. you know me better than that - ayc IS better than a good mechanical set up - but by how much? maybe like actual real value of a few percent, if that? on top of which apparently when you get to higher and higher power levels the mechanicals will actually start outperforming the ayc? what i'd love to see is a stock X (gsr) run a lap time, then only change is to swap out with a cusco type RS. i'd love to see the same with a IX but the stock rear diff is junk so more just to see what it does stock but with the cusco.

overall point is that for IX guys looking for the oversteer the AYC provides in the X, you can get something that behaves damn near close by getting a beefy aftermarket rear diff set up.. just check this thread https://www.evolutionm.net/forums/ev...ound-here.html - aka if the only reason you want the X is because it power oversteers but you don't like the other stuff it's worthwhile to look into this

obv all this is in regards to tarmac since we should assume the calculations the ayc makes are invaluable on loose surfaces like graven snow etc.



in terms of justifying ownership - obviously i can't say for sure since it's a hypothetical scenario but i'm pretty sure i would have gone the same route - a reprogramming of the ACD, which disables AYC anyway and a beefier rear diff like the cusco in back. reprogrammed ACDs play a huge role when you've got a competent mechanical rear set up to manage the increased front to back lock
