BoP (Restrictor and Ballast Settings) for RTR and other DLC

[speedrcr]

Wanted to know if anyone has experience and willing to share their restrictor or ballast settings to balance out some of the cars.

Planning on pairing a few cars for a mixed class race this weekend, however it's been a bit of work so far.

While we are limited in numbers of cars, it has been suggested by a few of us the following cars "may" make a good match up. However times and performance reflect otherwise, so we are going to use the Restrictor/ballast settings to optimize this.

Here's the match up and perhaps if you have settings to share, I would very much appreciate it:
Group A:
BMW M235i Race
Audi TT Cup

Group B:
Porsche Cayman ClubSport GT4
Maserati GT4

Group C:
Audi TT VLN
Porsche 911 Cup

Group D:
Mix of GT3 (undetermined at the moment, but these are examples)
Nissan GTR GT3
Porsche GT3 R
Audi 2016 LMS
Mercedes AMG GT3

Once again appreciate any input. We would like to make these balanced as much as possible and have taken a look at both Ai times from Qualify in Race Weekend as a base determination. Would run in Qualify only with 2 types 6 cars each, then take lowest time and compare difference, then adjust. However since you can not make these adjustments in Race Weekend (PC at least) it's been hard to get a good base line.

Also have taken into consideration the performance list that WallyM made in reference to Car Time ranking.

I would reccomend taking the car data (http://www.racedepartment.com/downloads/ac-cars-and-tracks-technical-data-excel-2013.5577/)

And calculating a basic power-to-weight ratio...then you can add ballast weight so that the cars are more even...that might be a good starting point.
