My first timed lap at Matsusaka with the default setup was 3.5 sec faster than my personal best in the Simtek GT3 mod! I felt completely comfortable with the default setup, though can see where a little tweaking to suit my driving style would help.
Sound is lively & crisp, like the FR3.5 when listening to trackside cameras. Quick check of youtube videos from the Japanese race series credibly match rF2.
