What are you're best times so far? Best I've got is a 1:59.6. According to RSR record so far is a 1:55.7. I drove the balls of to get a sub 2-min time, I just don't see where I can shave off over 4 full seconds...
I'm not the best tuner, but this is the setup I use for that combo. It's more geared toward drive-ability than speed. I can run mid 57s on mediums, so it should be about 1 second faster on softs.
I'll try that, so far all I've messed with is gearing, camber and tire pressure...
EDIT:
Tried your setup and lowest I could go was a 59.2. Guess it's just me I looked at the time splits and I'm pretty close to the leaders on the first two sectors but on the third I'm almost a second off. I'll try some new racing lines tomorrow...
This is the setup I used to set 1.56 on RSR. Didn't spend a lot of time on it, mostly just based on guesswork and feel. Apart from aero there's really not much time to find in different setups.
