mildman there is a website with all of the ipransw track, qualifiying, and race times of every competitor.
before i bought my car i searched it because i didnt believe the times that i were told but they were correct. they give the times for oran park, eastern creek and wakefield park
my car's times(not me but the previous owner as i havent had the chance) are:
wakefield park 1.11.9
eastern creek: 1.58.75
and im not sure of the oran park times but this is with an A15 in a 1200coupe racing in the improved production class.
the only trouble is that the website eludes me at the moment so ill try looking for it and link you to it.
for my times i have only done club stuff like the Mount Panorama supersprint, esses hillclimb, and the mountain straight hillclimb.
Esses hillclimb: 33.99
supersprint: 64.68
mountain straight: 62.45.
i havent done much driving in the car so ill let you know if there are any 1200's that are faster( there were some at the australian hillclimb championships but i was the first road registered one they did like 31.something ask dodgeman as he works with the winning 1200 coupe owner and he may be able to give you some guides as to what times he has been doing.)
hope this helps
