Quite an embarrassing post for me...

I took my brother's brand new yellow GT3 for a drive.
I ended up driving with a Yamaha R1 on my tail and started to push in the tight corners.
When exiting an S , I lost the back of the car , pushed more on the throttle, the car started to slide the other way, I steered the other way just to have the car skid again, by then I new I would loose the car...so I ended up sliding side ways in the ditch.
A very stupid drive from me
The car is not too damaged. I hit a pol on the side of the car, so the lower part of the car behind the front wheel is quite damaged , the side airbag went off, and a rim is also slightly damaged.
I hope the chassis is not hurt ( my main concern).
I guess I was lucky, could of been much worst. I drove the GT3 like my C4S, I putt full throttle when coming out of the sharp corner, I can do that with my C4S -20mm, but obviously not with the Gt3

So stupid of me , in every way !!!!
