Read up, you'll know the answer.......

 

IMNSHO there is no point in messing with the ACD if you're still running a stock rear diff. The TRE rear diff is the real deal if you're looking to eliminate corner exit understeer. Start with the TRE rear diff, then, if that's not enough for you, think about playing with the ACD.

I have an '03 Evo, so adjusting ACD is not an option for me, but ... with stock open front diff, stock suspension, the TRE rear diff completely eliminated any corner exit push. My only other suspension mods the last time I tracked the car were a rear trailing arm bushing and WL rear bumpsteer elimination kit. So, to recap: stock advans, open front diff, stock struts, stock swaybars, stock springs, rear TA bushing, WL BEK + TRE rear diff = neutral car.

I really think that along with the aforementioned bushings, this should be at the top of everyone's suspension mod list ... even before swapping to a bigger rear sway bar.

That's what im trying to figure out. What's best for buck, rear diff or messing with the acd ecu. advantages of one over the other and if im still not satsified, do both.

 

Exactly! Most people don't realize that getting more aggressive with the lockup of the ACD will send more forces to the rear end. This will cause more stress, more heat, and quicker wear at the rear diff than with the stock ACD programming.

The TRE rear diff upgrade strengthens the rear diff assembly substantially - as well as giving longer life and improving heat capacity.

The upgrade process should be as follows for an EVO with an open front diff : Front diff > Rear diff > Center diff

The upgrade process should be as follows for an EVO with a stock front LSD : Rear diff > Center diff > Front diff

 

I think it's time you actually drove my car.

 

I need to Bill, give me a call when you're free, (hopefully tomorrow :crosses fingers: ).

 

when you're exiting a corner with this mod and it starts oversteering do you have to countersteer or hold the steering wheel straight?

 

THat will vary from corner to corner. It also depends on how much throttle you are applying. More throttle = more opposite lock (countersteer).

 

bump for more people using this! seems great, cant wait to do mine

 

Mine is still going strong after 2 years. I love the fact that when you make a sharp 1st-gear turn at slow speed (not under load), you hear the rear diff go click-click-click as the clutch plates slide over each other. Let's you know it's still working!

Thanks, Jon, and Merry Xmas!

which did you get? 1 way or 1.5 way?

i wonder waht the advantage (besides price) is of getting this one instead of a cusco?

 

Gotta love the clicking noises. People look at me like my car is about to break when I am in a parking lot.

 

meaning is one better than the other?

 

yeah basically.. the cuscos what like $1500?

I searched for reviews for one like they sell on the ams website, didn't come up w/ anything tho
