Updated one of my older layouts, and drove the Pochete 118 GT3 mod by CarlosSainz55 round it.
All 44 turns round 7.0 mile / 11.2 km covering about 7km square.
I'm thinking of renting a server again, and if I do (depends if I can get lapper to work with it), then this is likely the layout I'll be using first.
The fiddly bit of the track is placed so that by the time you get there, your tyres should have good grip.
I've asked modder if he can add R2 tyres to his mod, as I'd like tyres to be bit warmer for single lap use.
