Anyone who has driven an Evo with AYC and a RS without AYC on the track will tell you the difference. I have and must say your entry, corner and exit speeds are so much higher with AYC working. The lateral Gs you can pull is unbelivable. It almost becomes an unfair advantage. Even full race teams in Japan swear by having AYC.

 

Without a doubt!!

 

are there any after market ACDs or AYC available?

If not, supposedly the MR does come in, then will those parts fit in the fully loaded 03/04 evo?

 

In past discussions, it was generally agreed that the cost and effort to get an ACD installed and AYC working would be substantial. The parts themselves should fit, but they're probably not worth it unless you're racing (in which case you could buy a JDM/Euro Evo and keep it off the streets).

 

ok then if there's gonna be no notable difference on just street driving or maybe agressive street driving, then what the hell is the big fuss about the MR? besides the ACD and AYC all the other parts can be done with aftermarket products; bigger turbo, cams, rims, shocks, aluminum roof?? that's a whole 9 lbs. go run a few laps around your block and drink some turbolax.

also, if you have the right suspension mod and setup, is it gonna be that hard to keep up with the MR that has the ACD and AYC? would it be that hard to have a .98 lateral G force?
I'm sure I read one of the cars in the SCC challenge had more or equal to a G in lateral force.

 

Front LSD, ACD, lighter, better suspension, more power.

All can be had, but not for the price difference between the Evo and the MR.

 

There isn't much of a difference on the street. That's why it's a "racing" version.

 

"The 2005 Mitsubishi Evolution MR edition, scheduled to go on sale this fall, will add an active center differential, six-speed manual transmission, more horsepower, a lightweight aluminum roof and BBS forged aluminum wheels."

So...there's a LSD in front instead of a open diff? I see the ACD part, but wheres the front LSD?
Excuse me if its blatantly obvious but I dont really understand the difference. Also mprtklr said that the vicious coupling acted like a limited slip diff....so whats the difference between that and a ACD?

 

I don't see AYC in that quote

 

Thats because the AYC will not be coming to the shores of the US. Which is a good decision by mitsu considering how many of you guys drag your boosted Evos.

 

no AYC?

why is it bad to drag with AYC?

 

agreed with jemm said, i just saw picks broken ayc's.... ours is stronger

 

Through the years, it has been shown that the hypoid gears and casing of the AYC diff are not strong enough to sustain high load launches. It is even worse with SAYC, the casing of which is lighter.

Did you know that the USDM rear lsd is the same beefy one that is on the jdm/euro RS model? That diff is so strong!

 

Removing AYC from the USA MR equation also prevents the 2 major ayc headaches :

1. Pressure switch failure.
2. Pump failure.

All of which are more common in COLD countries.

Having AYC removed reduces the purchase cost, and the maintenance $$.

couldnt agree with jemm more. Ive seen broken AYCs from guys who do hard launches. A another evo owner used to tell me he would say a prayer for his AYC before everytime he dragged someone. Some guys with launch control and big turbos even disconnect their AYC to save the headache. Personally, i prefer overtaking your challenger on the outside lane in midst of a corner and see the look on his face.. priceless
