2016 Porsche 919 Hybrid @ Circuit de La Sarthe (request)

I'm trying to put together a decent lap time at the Le Mans circuit (mod by Tiago Lima) with the Porsche 919 hybrid 2016. I have a theoretical best around 3:31.

Can someone give me some advice on how to solve some problems I have with the setup?

I have generally understeer entering slow corners, and exiting mid-fast ones, and oversteer out of slow corners when the electric motors don't engage.

Is there also anyone out there who can suggest me where is beter...
