YRF Update.
Last nights test running the car with wide kingpin front end on a medium grip fast but technical track was an improvement, i set my quickest qualifying time by about 5 seconds at this track i usually struggle at. A few things to try next week but a big improvement non the less.
The downside, the Tamiya and Zen F103 front rims do not fit, the kingpin is too long, only the yokomo foam rims fit which are a slightly larger diameter. Pit F103 tyres are still able to be mounted to the yokomo foam front rims.
High downforce front wing and medium springs was the way to go.
