this mod is awesome, unfortunatly their is something to balance (it's not very important ). Honda engine is less poswer full than renault. Hass is a way more strong than real life. Sauber is a way more weack. Actually sauber is just at 2/3 turn every race (IA 106% and i play Mclaren im not in a top team) Sauber can't fight versus other team. In real life they clearly can. Their is a probleme with the helmet of sainz, it still the same as Palmer.
For engines, Renault is just ahead of Honda. Ferrari is just ahead of renault and behind Merc. I think this years engine perf is more even between the 4 engine builders . Ferrari engine's customers got the same perf as scuderia. I think that's it. I put 4 star because of what i said. If you correct it it's a 5stars because you did an amzing job :D
