Default really.. how bad is it to track on a blown coilover..

so my shock is blown... and i cant get it revalved in time for the next track outing... how bad is it really to track on a blown shock. I've tracked on this blown coilover last event and ran my fastest time, but really how dangerous is it?

I drove a nissan 240sx with totally blown shocks before. It was like driving a boat. You can feel much more weight transfer/ un-balanced body roll.
pay attention to those bumps, apex curbs, or any other ugly surface.

However, I would ask for credit if I were you.

yea im wondering what do you expect? i've read that the corner might roll more... basically the kw is leaking through the compression adjustment hole.

A little seepage probably isn't "blown". If it's not spraying oil out of the seal you're probably OK. The spring rate isn't changing so, the car's going to have the correct ride height. A truely blown CO, you'll probably see either no damping at all so, the car's different in dynamic situations (corner entry) or the valves will get stuck inside and not permit the CO to have the full range of movement because pressure builds up as it compresses and your effective spring rate increases as the suspension cycles. I had that happen to a strut and ended up with a bent wheel because there was no give when I hit a pot-hole.

Well the problem is that if you operate with little or no oil in the shock. You simply will cause serious damage. Specially if you bottom out.

Yet like above I agree with leaking oil. Not exactly a full blown problem unless there is no oil left. Yet having one shock doing this may cause some unusual drive conditions. So watch those corners.

I wouldn't do it. My biggest concern would be unpredictable handling behavior, which you definitely don't want on the track.
