I did a quick test with some of the GT 300 machinery.
Here are my findings.
All cars were stock, using Hard tires and running on default setups.
Track was Nurburgring GP/D.
I did 5 laps stints with every car, in the order shown in the table, so when o drived the RX7 i was more confortable with this type of car on this track.
Without any surprises, the RX7 was the fastest, followed by the Celica and both the Lexus and the Impreza were more than 1 second slower. Again i want to remember as i was driving i was becoming more confident with the cars.
Having said that, in th RX7 i was quicker than the other 2 premiums on my 1st flying lap.
Next i restricted the HP to 300 and add wheight so the cars would be equal at 1200 Kg. You may ask why not 1150, wich is the higher now. Well, because then the Lexus would loose a possibility for changes in setup, a big possibility too.
Now i drived the car in an inverse order, so the RX7 was the first to hit the track.
I believe this settings may work. The Impreza is still too slow, maybe because of my inhability to drive 4WD cars, but the Lexus was much quicker now. Why? You ask. Because the weight added was minimal compared to the other cars. The Celica would be a lot quicker if i messed with the weight distribution, but that wasn't a option here because i wanted to test them on default setup. It had more 150 Kg, that needed to be ballanced, and its handling was 🤬.
I don't have a Arta, nor the money to buy one. Thats the reason it wasn't tested.
Hope this helps, and sorry for the long post.
