drifting st205, how'd he just get rwd? Options

[easternpiro1]

i know this video is old, and its a noob question, but how'd he get the car to be only rwd? i was told you cant adjust the front/rear bias, and its very difficult to make it only rwd... never been clear on how people did it...

At the end of every shot, it looks like it's going to smash into that track/pit divider.

[easternpiro1]

you think thats bad? look at my friend recking at thompson GA clear to drift! (youtube clear 2 drift 2.0)

[playr158]

2-sway LSD in the rear, and I'd be pretty sure that car is still AWD

ok gotcha! just more power going to the back

[95CelicaST]

Removal of the center differential will make it RWD. Take out the center differential, front axles, and put blanks into the axle holes in the transmission.

[Neon90424]

he cant drift worth ****

[SwissFerdi]

^ I think that's because it is still AWD. It looks like he chucks it in hard with the handbrake in the first shot, but notice how the rear never seems to truly slide out.

[Neon90424]

hes trying to drift like a rally car lol...asphault doesnt give...there's a reason why people remove the AWD on evo's and skylines to drift...

[njccmd2002]

(puts on flame suit)

so why cant we use the e154f and just cap the rear diff, and only use the FWD in our swaps.

we can. remove center diff, add fwd diff, add block off plate. BAM! FWD box.

[Neon90424]

expensive fwd box.

the easy way will have 50% of the power on teh front tires, and the diff will eventually burn due to friction.

this is the proper way of doing it.

and to be clear, removing the front axles to make the car RWD will have the same effect, only 50% of the power will make it to the wheels and the diff will eventually burn due to friction, the diff is designed to split the power 50 / 50 front and rear, then the rear is LSD ( OEM on the ST305 ) the front is open diff, that's how he manage to do a little drifting, if he had tires better suited for this,. it would look almost as good as any RWD car ( with a proper driver ) but he's using tires that have too much traction.

[Neon90424]

why not just racing slicks in the back and ****ty bald tires upfront

[stephen_lee]

expensive fwd box.

Not if you already had it in your clip, and find a busted/junkyard mr2 box. its essentially an e153 with gears mated to the 3sgte/celica.

3 options if you want a e series trans when you get the e154f with a clip

1. Buy a FWD e series (e153, e53, etc)
2. Buy & convert an MR2T tranny to FWD (using brackets and such from the e154f)
3. Convert the e154f to FWD. (using the MR2 diff, block off plate)


options 2&3 will require just about the same cost, option 3 requires a lot more effort as you will have to actually split the tranny open, but if you find an LSD(thats not already installed in a suitable trans), why not?

It all depends on what YOU want to do, your skill/tool set, and what is available to you.

[stephen_lee]

why not just racing slicks in the back and ****ty bald tires upfront

that would cause understeer BAD. WAYYY more traction in the rear, than up front.

you'd want normal street tires in the rear, super sticky tires up front. which might not even work dependin on how the center diff reacts to big differences in speed between the front and rear(IIRC its open, so it will send all the power to the spinning sets...)

I'd run with this tire setup and an aftermarket rear diff and stiffer sway/strut bar.....you'd be surprised at how the loose the rear end with get with that setup!

I got mine mixed up

Sorry i would run yours stephen....more grip up front and less in the rear is a smart way to break the tail end loose from what i noticed...

[stephen_lee]

just checkin lol i second guessed myself there for a second

the car is awd. sooo all u have to do is block off the front two axles hole with a custom made plate. u dont need the front axles the car will still go if u take them out. so if u take them out the car becomes a rwd car its not hard if u already have a gt4

No sir. Unless the center diff is a clutch type or viscous limited slip(ST205 is not IIRC, its just an open dif and will send ALL power to the axle with the least traction, in this situation the front axle) and this setup willl not last long at all in a racing application. A "locking" diff like was avaliable in the previous GT4s would last longer. That's with a simple block off plate.

Another option which would only work with an open center diff, would be to make the block off plate with an axle stud welded onto it, mating with the front dif and the plate bolted to the trans, essentially making it appear to the diff as wheels that are locked up, and the way an open diff works, the center diff will send all power to the rear wheels. But again, this wont last, but much longer than the first option

Best bet would be "weld" the center diff, then block off the front axles. but this is a pretty permanent thing, and pretty...shoddy way of doing it.

Edit: the "quote" was screwey. and added another possibility.

I think this should be in the main forum as it applies to the Celica and has pretty good info in it..

I don't know if all St205's received it, but mine has an LSD in the rear and a Torsen in the middle. What would happen if you'd block the front axles? Would it be a better way to get a Gt4 rwd? I guess it'd end up burning too eventually?

[stephen_lee]

A torsen/helical diff is an odd one. It requires SOME resistance on the wheels with little traction to transfer the torque to the wheels with the most. In this case I don't know of a way to fool that diff, other than welding.

If you simply block the front axles, the dif will send all the power to the free spinning side (front).

If you lock the front axles, the torsen will think the rear is slipping so it'll transfer ALL torque to the front axle.


UNLESS my my understanding of the different types of differentials are off. If so, someone please correct me.

[czwalga]

The ST205 doesnt have an open center diff. The front is open.


My understanding is that the center diff provides a non adjustable 50/50 power split between the front and rear. If neither front wheels are not moving and the rear is, for a significant period of time you're going to burn up the differential.

It's why handbrake turns arent recommended because you lock up the rear wheels but the fronts are still turning. That said i've done this many times, but try not to lock them up for vary long, just enough to get the car rotating properly, but I also have 2 other transmissions sitting in my garage waiting incase I destroy one.

[stephen_lee]

So its some sort of limited slip. I wonder which kind? Clutch type?

[czwalga]

The front is open, center is a viscous, and the rear is torsen. I'd prefer a clutch in the front and rear, however usually the only stock cars that come with those are rwd muscle cars. The plates do wear out though and when they do it almost acts as an open. But you can get a good amount of use out of them.

Ah, a viscous will not last long at all. It would heat up pretty quickly and kill the fluid.

I'm running a viscous in my V6.

[CelicaST18]

you could weld the center diff to make it fixed front to rear and take out the front axles to make it RWD.. like i did in my WRX had no problems with the center diff and its reversible.. just need another center diff
