Is my car rear biased?

So I was seeing how slippery out it was this morning, and it seemed like the rear of my car wanted to come around really easy. I thought I read somewhere it was 50/50 split on the 5mt's but now I'm not too sure.

What model year and model car?

Previous years WRX and STI's had a rear torque bias. How much depends on how you have your diff set (STI) or was mechanically set (WRX).

 

Sorry, its an 09 wrx.

 

I'm thinking this might be more a factor of weight distribution then drivetrain bias.

 

I found this on drive.subaru.com

I was under the impression that the 5speed had the 50/50 planetary gear thingy. This could be a weight related issue, since the motor is up front it could give you more traction at those wheels. Another possibility could be suspension related if you are seeing this happen on corners.

 

you can get the rear to come around very easily on fwd cars too

 

That makes sense. I was pulling out of my work parking lot today and the ass end slid out like it used to when I did such a thing in my Mustang back in the day. Thought it was odd.

 

fixed. ;-)

 

Just got done doing that a few minutes ago :laugh::laugh:

 

I'm no expert, but I think as long as the rear tires are being driven at all there is more of a chance to bring the rear end out, especially if you are going around a tight turn in 1st gear.

 

A viscous coupling means no rear bias. The locking rear makes the car feel like it has a rear bias.

Unless the car has a 6mt or a newer auto with the other variable drive(the name escapes me right now), its like any other subaru.

 

mine likes to swing out the ass-end like a rwd, thats how i spun around today. It surprised me quite a bit and its a 95...

 

My '92 beater wagon steps out too when I get on it. Doesn't mean it has a rear bias.

Its a lot slower to step out compared to the sedan though. A heavy ass is just that, a heavy ass.

 

This is why. Also weight transfer helps too.

 

'09's have an open rear diff, afaik, with the usual viscous center. No torque bias anywhere.

 

I thought the WRX 5mt had a 45/55 front to rear power split due to the 1.1:1 ratio of the center diff. I'm not sure if all the model years of WRXs have that though.

 

I wonder if tires have anything to do with it, or maybe hatch vs. sedan? My 09 sedan pushes pretty bad in the loose stuff. I have to purposely flick the car to get the back end to step out. I'm running Conti-pro all seasons on the stock rims.

BTW, I've never owned a Subaru up until I bought this one in September. After yesterday and today, I'm pretty much convinced they're the ultimate winter fun car.

 

I'm running Hankook Ipikes. They plow through this sh*t like crazy! I drove two coworkers home this morning and drove my dad and his girlfriend to work today.

 

The only way i was able to get my 09 to go sideways was without TC on and to really push it. Which i did plenty of last night otherwise i was stomping on it and it just wouldn't budge.

 

my co-driver for the night twas right. he twas able to get her sideways, and a good white out. but my point is we had to try and do it. it wasn't going sideways unless we made it. it is funny that the TC was on the second time around.

 

Also remember that when you're at these intersections, and go through turning 90*, the rear tires will follow the RUT/tracks, which was created by your front tires and the rear will swing around where you turned. It may seem like the rear KICKED around, but really it was just following the ruts/tracks.

'08+ WRX doesn't have a VLSD in the rear anymore. No need for that when they have traction control. Performance driving however is diminished when tire slippage is needed to rotate the rear.
