XRAY - Model racing cars

Hello. We race with foam tyres 9 years ago more or less in carpet.

For more steering we cut the diameter of front tyres 3mm aprox. compare with rear tyres. Normally with rubber tyres, we have the same diameter front and rear of tyres.

With parameter of setup can I do for get the same effect? I would like to get more speed corner.

You would need to post your setup but I know most people drop from a 3.0 kit front spring on a T3 12 to a 2.8 to get less initial steering
