Hi,
Today in extreme cold weather my son totalled his Subie.
Total write off with serious frontal damage. Wondering how come air bag
did not pop?! Looking for a upgrade to WRX(not STi version). Any
comments/suggesions on couple years old WRX? Can't afford brand new.
We are just glad accident did not involve any other person or property.
He just destroyed his own car losing control side ways, Sigh!
Aside from the issue of whether an inexperienced driver (and you don't
mention how old or experienced your son is; for all we know he could
be a 40 year old ice racing champ) who totals a 2.5RS should move up
to a WRX (or STI), let me toss my two cents worth in on the topic
since I have some relevant experience here. I had a 2.5RS, that
replaced an Outback Sport that I felt was underpowered and too softly
sprung. Turning out of a driveway onto a road covered with light snow
(no traffic in sight, with relatively new, original all-season
Bridgestones) I punched the throttle to see how the tail would react.
The rear came out as I had anticipated, but wouldn't come back
regardless of my steering correction and throttle control. The car
eventually struck a high curb that and cracked a wheel. a 2" by 1/2"
chunk of the bead wall came out, but the crack didn't spread; tire
didn't even lose pressure and I made it home (still holds pressure and
I keep it around as an emergency spare).
Now, many of the "performance" cars I've owned (WRX, Z-28, SE-R,
Corvair) have had limited slip differentials which, regardless of the
driven wheels (and you'll note that the 4 I mention are all different
configurations) allow traction to be shifted away fom the driven wheel
that's lost traction. This can enable the driver to apply throttle,
coupled with steering correction, to use the remaining rear driven
wheel to pull the car out of the "drift". I ultimately replaced my RS
with a WRX and since have attempted to duplicate the "accident", at
progressively higher speeds. With the LSD (no I wasn't tripping), the
rear caught and was recoverable, in every instance. I love the WRX,
but would have been happy with the RS if it had been available as a
wagon (which it eventually was) and with a rear LSD (which has never
been offered).
Is the limited-slip differential a cure-all? No. But it's an
inexpensive mechanical solution to a common problem, and should be
more widely available. I hate the idea of the high-tech alternative:
traction control systems that apply braking force to a wheel losing
traction. Defeats the pleasure of studying the limit of adhesion and
learning how to power through that moment.
You can get the same effect with some left-foot braking.
