Oversteer!!
Hi,
I have only owned my scooby for about a week now. Im just getting use to the 4WD and power delivery which I cant fault at the moment.
I havent been cornering too hard as I wanted to find out what the handling was like and wanted to slowly find out how a 4WD car takes corners.
Last night I took a friend out and found a nice big roundabout with no other cars in the area. I thought it would be a good chance to see how much grip she has got
Anyway about half way round the roundabout the backend started to drift out. Not much but enough for me to have to correct it!!
No major dramas but thought that these cars suffered with understeer not oversteer. Do you think there is something wrong with my set up?
The road was dry
Oh and I own a UK Impreza 2000 model
Thanks
Dan

Hmmmm a few factors can cause oversteer, lifting off so that the transfer of weight moves causing the rear to go light and a bit "wobbly" or there is the factor that you could have 2 different types of tyres on the car, which can give you different levels of grip (a reason to check your pressures also, but to keep the same tyre all round for similar grip) or you could have hit a damp patch which may mean you loose grip on the rear.... but mainly scoobs will understeer rather than oversteer (unless fitted with either dccd or a-dccd where you can dictate whether you want under or oversteer).

What you have to be careful of is that Scoobies tend to power understeer, so you get to good cornering speeds, give it some more gas to see how far you can push it, think 'this isn't working' lift off and hey presto: oversteer city! Another common scenario is that people get too carried away in the straights and carry to much speed into the corner, realise their mistake, brake during hard during the corner with the same result. Take it easy, they're forgiving cars generally, but -contrary to what some press reports might have you believe- sooner or later you answer to a certain chap named Newton...................and he always wins!!! I wouldn't advocate practicing your car control on deserted roundabouts: get it wrong and a kerbstrike could mean an expensive bill!!!

may have been me lifting off then. What I did was went into the roundabout at a set speed, then went a little quicker, lifted off and then went back on the gas. During this time the back end went out, thing it was when I lifted off.
Might just be my driving then
All tyres match, have correct pressures and same tread left on them
I was just a little worried that it was just down to poor handling. As I have said I am trying to get used to driving a 4WD car, all new to me at the moment
Thanks for your help mate

can't beat a bit of oversteer m8 cause you can control it more! its the understeer that does my head in! only way is to stop it is let off the gas, too late and ur most likely to carry staight on into a hedge or summat.
Bring on the oversteer i say!!

Have you had the 4 wheel laser alignment done for Prodrive settings?
If not I would highly recommend it, single best mod you can do to a scooby (imho). The handeling i thought was OK, until i did this, now it's awesome!

Thanks for the advise. Is the alignment something that I would need to get done at a proper scooby garage or will my local tyre and exhaust place know what I am talking about??

mainly due to the fact that you can only ever get a skid on the front of a car as the wheels there steer Tony

i didnt say they were rear wheel steered, i said they had rear wheel steering
they can still skid if the wheels turn, are you saying you can only skid if a steering wheel is involved?

To control a skid, you have to be able to turn the wheels, thus controlling the car, unfortunately with passive (note the word passive) rear wheel steering, you have no control over it, so you dont steer the car via the rear wheels (thus passive and not active).

Skid.... only ever happens in a straight line, otherwise you either under or over steer.
That about sums it up

I've the same "problem". My car is oversteering too much or may be too early i dunno but I like the way she go =) I think it gives a better control rather than dealing with understeering.

what happens when you reverse your car and hit the brakes, is that a skid

ANy 1 here ever try a older 20vUrQuattro, this car is unique in that it usually understeers, but its torsen diff allows it a neat trick, it can switch from under to the slightest oversteer in extreme cornering. Very safe.
