Group Drifting&OverGrip Limit Handling Course - 23.03.14
- Thread starter CATDT
- Start date
So you get the Champagne for being last too :?:
Having done this course on Sunday, here's what we got up to:
Most of the day was spent on the steering pad which is a big concrete square they use to work on under and over steer. We spent a short time before the morning and afternoon sessions in the CAT hospitality centre where Colin went through the engineering theory of what we were going to experience. In the morning we used their caterhams to learn and practice the basics of oversteer, reactive correction for the slide and drifting.
After a nice lunch we then used our own 964s to do slip angle mapping and experience the limits of the car in cornering. This essentially used the approach road to build up speed so that we would enter the steering pad at about 70 mph for a medium 180 degree corner designed to experience trail braking in, balancing the throttle to the apex and then the power phase to the exit. This let us experience the limits of the cars in the dry, how to reduce understeer and how to correct for oversteer. The steering pad was then wetted and we did low speed drifting round the centre of the circle and then moved on to higher speed power oversteer. The latter used the approach road again so that we entered the, now wet, steering pad at a good lick. This was the most fun because it involved trail braking to the apex, then lifting off while there was still some steering lock on to hang out the tail and then use power and steering to drift the car out to the exit. And of course spin every once in a while!
Thanks to Jo an Colin for an eye opening and enjoyable day. :thumb:
p.s. I was knackered by the end of the day. :grin:
