On the track it can help, especially in the rain, in rally it's everything. I can say from experiance that AutoXers will like it once they get the jist of it. If you do not know what is going to happen when, ACD will cause you to loose it(go off) bigtime. If you understand what it's going to do, and for what reason, and when, you will become a rock star in a hurry, it's that killer.

I don't think JICcoilovers qualify as a real suspension, they are just street lowering junk like Tein or Tien, what ever they are called. "Tunner" garbage and hype go a long way.

Differencial choices(frt and rr) and setup are more important than dampers.

There are two performance ACD control boxes available from ralliart.

There are guys who make a living entirely from mapping aftermarket controllers for ACD. However the Ralliart versions are so damn good most use them.

There is still hope we can get the Cusco 35f/65r center diff. This is the ultimate solution

 

You will see that Mitsubishi has never homologated AYC for the RS cars. Reason is it's just a gimic BS sales thing, useless for anything but *******.

The ACD system is the big gain.

 

How much difference will a person like me notice? I mostly just commute w/ my car and fly around the occasional corners. I might go auto-x like once a year.

 

Haha. Probably never.

I autox often, but I haven't actually done a track day yet. I plan to do one before the summer ends, hopefully, but even then, it might be awhile till I get the jist of the car at higher speeds (much diff than autox!). I think someone like me might not be able to tell, but until I can drive a car with ACD I wouldn't know...

 

You will not notice it at all on the street unless your being stupid(driving real fast). Pretty much gotta be on the limit, that's the gain, you rasie the limit, so if your not getting close, you will not sence a thing.

For most people ACD will be a waste. For people that do track days, seriosuly autox, or drive like idiots on the street it will be worth it.

Save up some money when you do that track day... the car is one of the best IMO for someone with no track experience to just get out there and turn some quick laps, but it will make you hungry for even more performance... not that you don't have a lot as it is..

I did my track day, then another, then another. A set of tires, brake pads, catback, and intake later, I'm looking hungrily at the Quaife.

 

Quaife are junk. If your stuck on Torsen get a stock front RS tarmac diff, I have one slightly used, like 2000 miles street use.

I highly recommend a KAAZ plate diff.

I agree with everything you say except this statement. I am only talking about the FLT-A2, which are used on several very succesful racing cars. Sure there is always better you can get, but these certainly aren't "tuner" springs.

Do you actually have any data that shows the ACD to lead to faster lap times, etc. Is it even used on a WRC car too (specifically on tarmac courses). Like I said all the data I have seen is only comparing stock evo's. All the racing evo's I have seen have dropped it, or did not get it in the first place (7 RS where it is an option only)

 

My question is will the acd be able to handle the 400-450whp most of us will be throwing at them? Can it handle continuous high rpm launches at the track

 

Hm, can you expand on why Quaife are junk?

The problem is that the US spec cars have unique transfer cases, so we can't get front LSD's designed for Euro/JDM cars. Quaife is making one designed for the US spec Evo8 as we speak. Also, I do not know if the RS front diff will work on our 03 Evo's. Does anyone know?

 

I don't think "most of us" will be doing 400-450whp mods. But that said, if you plan to be dragging your Evo, just get an '03/04. The ACD ain't gonna do you any good on the strip.

 

What successful racing cars? uninformed rich kids in Speed world chanellge don't count, either do time attack *******. I realize they are a good "street tuner type" shock but they are not professional racing shocks. And they have little effect on ACD.

The new WRC car has passive and the drivers hate it. They have made damn sure they have all other systems dialed in before they jump on ACD which is very complex from software angle. Remember the WRC car is not even close to the evo's we drive.

Standard accepted numbers are for gravel .4 to .5 second per KM faster, that's like a second per mile dude, huge. Mind you, this is only when driven properly. You can have a dogbox but still not get a gain from it if you can't drive to begin with. The ACD requires the driver to know how to use it.

Tarmac numbers are .2-.3 second per KM faster, still huge.

Most teams get rid of it as they have lack of knowodge about it, or have developed passive systems they feel comfortable with. And already win. When the 7 came out the Rally teams shuned it as they had expert experiance with E-6 cars, and a **** load of spares on the shelf. But once someone started to develope the ACD on the 7 it was a full on transfer to 7 cars.

 

Here is a link to a doc about the Japan spec Evo8. It describes a bit about what ACD and SAYC are supposed to do. Pretty good reading.

Im getting an 05 because I personally can get it cheaper than an 04. Acd means nothing to me as it will be a drag car. Im just currious if it can handle the power.
