Feel for you bro.
So uncrashable skyline GTR????
Almost the same as you - unfortunately (or fortunately), the R33 GTR was mine.
Small roundabout, slightly damp, but a roundabout I have been around a 100 times.
Chatting to my mate, not bombing it. Music on. Just get off roundabout, boost creeps up and BANG - I'm spinning around. Popped up kerb, hit signpost and sigh.....Mate got out an was sick. I just felt it.
All in, 5 secs and 30-40 mph.
My fault??? Probably but just goes to show, don't have to be being an arse to crash.
I have honestly went around same roundabout 20mph faster on other occasions without a twitch.
Conclusion - bus depot is on the first exit of said roundabout. Diesel?? Probably.
No excuses...but does make me more cautious on road conditions.
Also trashed a 916 due to over confidence in the rain on a track day.....just thought I'd mention that one. And yes.....TOTALLY my fault.
