Mazda 787B ’91

One of the most legendary and epic race cars ever! Even if you have never driven it I am sure you have seen it a million times before. I just had to make a tune for it. The power to weight ratio alone is just insane. It has 100+hp more than its weighs! Just crazy. It is a very fast car, of course, but it was a lot more difficult to tune than I was expecting. It had a lot of understeer and oversteer. Adjusting for one only made the other one worse. On top of that, it needed a lot of transmission and LSD testing as the wheels just would not stop spinning. However, after lots of trial and error I finally have a tune I am proud of.

It is much easier to control than it once was, and the laps times are much quicker, too. Best of both worlds. I even got a quicker lap time with this at Monza than I did with my Chaparral 2j, which is not easy to beat. It is a race car, so do a few laps to really get the hang of it. It is also a fan of larger tracks due to all the power, but does well at smaller ones too.

    Without a doubt my favorite car in Gran Turismo. I love the way it handles, the way it looks, and the way it SOUNDS. Awesome car

    • I agree. It’s definitely a special car.

    Can you maybe do an HKS CT230R drift tune? Without any tuning I can get 9000 points on Tsukuba, and I’m not good at drifting at all

    • I did it already. Type it in the search and it should come up.

        Thank you, didnt know that

    Does it work with the Stealth Model?

    • I would assume so. They are basically the same car.
