Tested the last version and current (v4.0).
The last version Harder tyres had a very low grip, and it was hard to have traction out of corners. Current version fixed that and being easier to maintain appropriate tyre temperature and better grip on hard tyres in (tested in race with C2 and C3).
However, I believe soft tyres (C4) still overheats and loses grip to fast. Tested in Bahrain qualifying, the sequence of turn 11,12 and 13 on the last sector all tyres but the front right overheats and you lose all grip and have to back out a lot, compromising the whole lap. So much so that the medium C3 is faster in one lap because you don't have to back out in the last sector
TLTR: good idea for mod, still needs more feedback from testers and some more updates
- C4 tyres overheat too quickly, C3 is faster even in 1 lap pace because it doesn't overheat so much
- Harder tyres (tested C2 and C3) now have a good grip and a good balance of temperature management needed
-Based on C4 experience C5 is probably overheating as well
