| there are 3 different types of tyre wear at norfolk:
1. rain. dont bother changing road wheels. i did norfolk in the rain didnt change and kept the tyres for a further 6 months
2. dry, morning. tyre wear really minimal due to dusty track, 1 set before lunch
3. dry, afternoon. moderate, similar to silverstone ATC
last few days i have been there i have used 3 sets with 6 cars there, so with 20 i doubt you would use more than 2 |
