EVO 4 Handling (Drift)

[EVOIV]

Hi,

I would like the change the handling characteristics of my EVO 4 GSR. I am aware that the GSR comes with AYC which is supposed to split power between the wheels when the ECU senses a loss of traction. I have heard that this is not a particular good thing, if for say drifting takes your fancy :) I would like the car to oversteer a bit more, but not too much such that it makes handling in the wet a complete mess! How can I achieve this?

Should I:

1) Replace the AYC with a LSD? Although very costly!!

2) Use stiffer springs. My car has the factory suspension. I've heard that using stiffer springs results in less bodyroll, but may cause traction problems. If I replaced my springs and used the same spring rate for front/back...I would have less traction at the rear of the car making it oversteer more often?

As you can probably tell, I have drifting my EVO in mind :) I know that the EVO doesn't have the best (FR) layout for drifting, but nonetheless...how many people actually drift their EVO? How well does it drift? I've seen the JUN Super Lemon EVO5 drift, and it seems fine :) But then again, my EVO has not been setup as such and I'm sure my drifting skills are far inferior to the JUN drivers.

Any help?
Cheers...

no mate, just chanche the settings of the camber. speak to evo-7 (sam elassar) he has the settings for that and speak to adevo he is the best for that :D he is a powerdrifter

Hi,

Do you know the email addresses for evo-7 and adevo?

Can anyone really explain to me how negative camber on a car can make it oversteer? This is an assumption.

I am assuming I'll need to use negative camber at the rear, and leave the fronts?

Cheers.

If I'm not misaken, negative camber up front then close to 0 camber at the rear gives oversteer.

This is because as the suspension is compressed over the course of a turn, the tires lose part of their contact patch on the road if set at 0 camber (design of the suspension). If the tires have negative camber then when the suspension compresses while turning it regains full or close to full contact patch of the tires on the road enhancing grip while turning.

Hence, negative at the fronts and 0 or close to 0 camber at the rear improves front-end grip while turning whilst the rears lose theirs.

Cheers! :D

Anyone correct me if I'm wrong. ;)

Evo IV,

If you would like to drift without the AYC "helping" you out all the time, then just remove the fuse which is situated on the +ve terminal of the battery.
One is ABS and the other is AYC.

The AYC light will come on to inform you that the AYC is not working but this is fine and will not damage your AYC unit.

This disconnection procedure is in the Mitsubishi Lancer Evo workshop manual.

Hope this helps....

Do not dial too much negative camber at the front, because you will end up inducing understeer as the contact patch will be smaller. I'd recommend no more than -2° at the front.

Also, take a look at rear convergence. Neutral or slight divergence (1mm) will induce some oversteer, but might make the car a bit unstable under braking. Some people here are running even more divergence at the rear, but the handling will become a bit tricky.


I'm not sure that by switching off the AYC you'll induce understeer. You will simply be running an open diff. Try it anyway and let us know what happens.

If you remove the fuse for the AYC then the rear diff will be open and all you will do is spin the inside wheel and not oversteer at all!
