Out-braking someone and catching up with someone via braking are two different things... he was talking about the latter. You could loosely interpret the former to mean the latter, but that's just not good enough for editing purposes -- put the latter way, the line is not only more accurately translated, but easier to understand as well.

I think know what you mean, but I've certainly heard the term used to describe someone who's making up ground in the braking zones. But I certainly agree with your point. :)
--- Quote --- And as for the power distrobution, last time I was down at Subaru, I asked about them, and the guy mentioned that off the shelf they're 50/50, but the ecu alters the power requirements as you drive, so they can actually be any number of ratios, instead of ones that off the shelf are locked to certain ratioes (There's a version of the Monaro here that is four wheel drive, with a 35/65 split all the time, regardless of driving conditions and so on)

Said it before, and I'll say it again, dealers don't know dick. The new STi is 35/65 by way of a planitary gear diff attached to the DCCD clutch system. The DCCD tells it how much to lock up, but it's always 35/65. The automatic Subaru's are FWD first, since they use a clutch type computer controlled center diff (even the Outback VCD and WRX cars do, but they also have the planetary gear like the STi does), that doesn't stay full lock unless it's needed. My car is 50/50, no way to adjust it, since all the diffs are mechanical.
This is taken straight from www.subaru.com:
--- Quote ---Driver Controlled Center Differential (DCCD) AWD: Exclusive to the WRX STi. Features both manual and automatic modes, uses an electronically managed multi-plate transfer clutch in conjunction with a planetary gear-type center differential to control power distribution between the front and rear wheels. Normally, DCCD splits power 35% front and 65% rear. DCCD also features a helical-type limited-slip front differential and mechanical limited-slip rear differential.

--- Quote ---Rally drivers use a base of a standard FR 4 wheel drift in most cases, especially for hairpin turns, or anything past 110 degrees (More than a medium turn), thus on a road more than 30 degrees but less than 55 degrees, it is possible to appear to be sliding, but still driving in a simple manner (And at a fair degree faster than an FR, because the power distrobuted to the road means that the rear wheels won't slide much, if at all)

A car doesn't have to be full sideways to be drifting. Even a small slip angle, like 6 degrees, is enough to be considered a drift. Too many people confuse powersliding, and oversteering with drifting, they're not the same. Even on relativly slight turns, the driver usually has the car drifting. However, with how much WRC has advanced, the cars have alot more traction, so at times, it is easier to take a proper racing line with no drifting on easy turns. That was a big gripe of Carlos Sainz's before he retired.

holy crap that was long. Wanted to kill two birds with one post. :p

Damn Just_J you break a sweat writing up that post? Very informative and well researched, i love this forum, i learn more about cars in this forum than i do in some car forums.
Sti_Brumby:
The Subaru employs an electromagnetic clutch on the center differential. Under normal driving conditions, say you're just cruising down the interstate, the diff clutch is disengaged, and 65 percent of the engine power is routed to the rear wheels, with the remaining 35 to the front (a 35/65 front-to-rear split). The car's engine computer adjusts that center-diff clutch, based on information from the yaw-rate and throttle-position sensors, and can send as much as 50 percent of engine torque to the front wheels. So the Subaru varies the torque split between 50/50 and 35/65. The driver can also manually select the torque split via a center-console switch.

man i am never tought stuff like this in my school. and i go to a tech school...(not full tech, highschool tech with half of my day spent in a shop related environment.)
