For the wrx is it corect that is a 45:55 rear bias split? Thank you.

from what i have been told the sti is a 35-65 rear bias split that is unadjustable. the sti does have an adjustable locking feature though that the wrx doesnt have
the wrx is 50-50 from what im told. |

the DCCD adjust the lock on the center dif from what i understand if it is unlocked or "loser" you get better traction but sacrifice the the horsepower getting to the wheels it slips more and transfers power to wheels that are getting good traction while it is locked well its locked and all four will spin at the same rate thats my understanding of the system the only thing dccd does is give you the option to do it manually instead of the car doing it |

Wow great read! I'm going to read that a few times haha. I'm having a hard time understanding a lot of how the Subaru awd system works since I'm a Jeep guy we get 50:50 split front and rear with open diffs so my brain is having an issue imaging what's going on here. In a stock jeep if you put it in 4wd and lift both passenger side tires off the ground off the ground the Jeep won't move. Is that the same for the WRX? What about the STI?

I'd also like to add in a Jeep with it in 4wd if you lift both front or rear tires off the ground the jeep will still move forward. Is thiss the same for both wrx and sti?

yes, all wheel drive, as in all of the wheels drive the car. I don't know why this matters/what you plan on doing....but if it involves having 2 tires off the groud often you might want to stick with the jeep

I'm just asking in that manor so I have an idea of how the awd works with the wheels being in the air thats the least amount of traction possible. So your saying both wrx and sti have LSD in the front and/or rear axles correct?

omg come on man, http://forums.nasioc.com/forums/show...php?p=15812529
read that. sti is true awd with diffs in front, read, and middle. wrx 02-07 i believe is an open fron dif, has a dif in the center and read. 08+ wrx is open front and rear dif, has a center dif. did this to reduce stress on the transmission. |
