Apologies, I didn't notice that.

I still wonder if a clutch type Cusco with the 1.5 setup is more forgiving controlling the rear end when lifting off the accelerator than a gear type quaife LSD?

Probably has a lot to do in how the clutch diff is setup. It can be an aggressive or a gentle depending on the spring and clutch selection.

With my setup when I have got the tail out from applying too much power and breaking traction, as I lift off the power and quickly too, the rear end quickly straightens itself and that's with the VDC button off in wet or dry conditions. I have gotten away with a lot.

So it seems I got -2° camber on the rears, thats thr best the alighnment centre said they could do.

I am now thinking of purchasing a reae camber kit to adjust it back to 0. I have been told this will be a sound move to regain some traction under WOT?

Isn't that the yaw sensor taking over?

Not with a 1.5 or 2 way clutch diff.

tbh I find this car can rotate/snap over a bit quick. Even in video-games it was depicted to do such

I remember when I switched to EcuTek's TC, set that to like, nothing, and then pulled out of a parking lot I typically put some gas into since I'm trying to get on before cross traffic comes again. VDC light never came on on the previous instances so I really didn't think it was ever too much power going down yet.

Luckily didn't eat it, but kinda went like this:

I didn't realize that he had a clutch diff. But unless the yaw sensor is disabled isn't it still going to try to control a fishtail?

Yes it can. I have found it to be less intrusive with my OSG LSD.

With the VDC off. It is still active some what. When the rear starts to come around. It will apply a rear brake caliper to straighten the car out. Usually in the wrong direction. With the YAW sensor disabled. It eliminates this.

Exactly. I never drive with my VDC on, I still need to install a switch for my yaw sensor.

So if I disable the YAW sensor will it be beneficial to my situation, or should ECUTEK TC be handling everything?

Haha listen to this clown, he has missed the whole thread and then comes on and talks trash. I don't run WOT on open public roads you retard.

In the middle of the 3rd gear pull the car violently and suddenly spun to the right and then to the left before I made it come to a halt. It scared the **** out of me!

Why did that happen? I have Pilot Super sports 275/35 on the rears and I was going in a straight line under WOT, then around the 4000RPM mark it almost felt like someone grabbed my steering wheel and threw it to the right and then to the left!! There was no gradual loss of control sliding etc, it just happend so suddenly out of nowhere.

Anyone else experience this before?

New tires dawg, 305 rear 275 front, MPS4S is a good start or r888r's

Thanks for the input bro, appreciate it.

So the MPS4S, would that tyre be similar in grip to the PSS?

So is the PSS 275/35 rear really not that good enough for TT power?

What a waste of money that was then
