Planning on putting a stripped out Justy back together for Street driving with the occasional Winter Autocross race. This is the kind of racing on a large gravel parking lot in winter using traffic cones to mark out a course. Which means that the first few runs around the course one has to deal with packed snow drifts that are 100 to 200mm deep over patch's of ice on the gravel. Once the cars have gone a couple of rounds with everybody racing, the course is more established with the snow slung aside revealing the gravel underneath.
This kind of racing really favours a LITE four wheel drive car with a low center of gravity and a short wheel base. A reasonable amount of horse power really helps too when it comes time to muscle thru those snow drifts.
The fastest cars are generally Subaru Impressa STI cars with a warmed over engine and carefully selected WINTER tires.
However there is a couple of epiphany's. A Dodge Neon that has a very high horse power turbo engine and a rally prepped(full cage and non open front diff) Volkswagen Jetta. These last 2 are front wheel drive and are as fast or rarely faster than the STI's.
When I race a stone stock Justy it comes in, in the middle of the field. About the same time as a stock N.A. Impressa or older stock turbo Subaru XT. It could really use some extra power to help in the snow drifts, but later in the day Iam not that far behind the leader's when the course gets established. That is the Justies lite weight helping out.
The Justy is only available with an open differential in the front and the rear drive axle's. There is no differential from front to back, when engaged the rear drive is locked.
This means that when one front tire is on ice and spinning the opposite diagonal rear tire is the only one that will spin. This gives the Justy great traction for a car with open diff's.
My fantasy which I believe is realistic is to modify my car with a turbo and some suspension mods to win this race.
This thread is about my Idea to add a second Emergency brake handle. Which would be staggered more towards the rear, so that without looking the driver can pull a brake for either just the left or right rear wheel only.
Often the course has some very sharp corners which are best negotiated by spinning, over steering or drifting. whichever term you are used to.
My idea would make the back act as a skid steer vehicle with the ability to lock up and drag the inside tire and all of the power would be directed to spinning the outside tire. Should make for a rapid change of direction on the ice
This is a picture of my stock Justy at the Apex of a corner, marked by the cone. Iam going about 70 KPH (42 MPH). ;D
