I was looking some help with what base settings to use for 10.5 pro stock. Local track is considered high grip, with around 12-13 sec lap time. I had read somewhere to just choose Mode 9 and leave it at that???? Also what FDR should I start at.
Thanks very much in advance for the advice.
For 97305 optimum FDR is 6.4 - 6.6 for indoor lap time 13 secs. IMO mode 9 is too hot to start with. Modify the setting by turning down fixed timing to 16, especially if the track has a lot of tight turns. If its flowing use 20. If you are incredibly smooth you can use more. The motor/speedo has awesome grunt and if you are aggressive with the throttle you will heat up, but not go any faster in lap time. Monitor your motor temp by reading the telemetry each run. If you're peaking at 85 deg C ish internal its on the money.
If you use 12.3mm BRCA rotor you should in theory gear shorter but it doesn't quite work out like that especially if you use dependent timing, its intelligent and gives the motor what it needs. If you gear it the same (ish) as the big rotor, 6.4 - 6.8 it seems to work out great.
Also on temps, sometimes I found the small rotor ran a tiny bit cooler (??) and was less prone to fading, I cannot say for certain why. Strange.
Generally I'd say run the big rotor when possible because the brakes are massively better with the strong rotor, but its down to your preference. Car flows more with a smaller rotor, depends on your style.
