v1.10 v2 is the fastest setup for current patch which i use with TC2.

The car might be a bit on the edge compared to v1.10, try run it with 7 roll bar or 69 rear ride height.

If you still struggle on throttle, even when the steering wheel is open, soften front bumpstoprange or go stiffer on the rear bumpstoprange.

There is not much really what you can do about the bump in the last chicane, don't take it short or run to wide.

Brake bias and TC are personal preference.
