Welcome John,
11.3 is a great time on a damp miserable Crail surface, well done
bam_bam - Crail is an old WW2 site, not really maintained but the track overall is pretty flat. There's a slight downhill section in the braking zone I suppose, but the main 1/4m is like a pancake, the launch pad is nothing like you would get at Santapod, traction can be a struggle, Crail's main flaw.
A plug for my own video in my old TTRS below to show you the track, but that's just to rub it into John that the mighty 2.5T TTRS managed it 1/100 of a second quicker in 11.37

Although I did get a much better launch at 1.72 60ft and a slower terminal speed.

I currently have a 2.0T Audi S3 (8V new model) and have managed 11.90 at Crail with that a few months ago. Nippy little cars with a tune.
I have an RS6 ordered for September delivery, I'm sure I'll get that into the 10's soon after
There doesn't appear to be a big 4.0TT scene here in the UK yet, I'm sure that will change in time.
