What track is this for?

If you say “all around” Im not driving it. Im not going to try to work where its good for.

3

It does pretty well at Bugatti and Sebring. Im still trying to figure out where its good myself. Tracks that need a lot of acceleration is where it seems to accel.

4

Tsukuba and Motegi.

Wait, my bad.

5

Our builds are very similar and i like mine at Sebring full, prague short, and the long top gear tracks

6

Copycat lol.

When I first built this car it was at 577. I think you meant sport Centrifugal as this bought it up to the boundary.

I ran the car at bugatti.
#298 1.48.5

The car handles nice but has a little understeer. Possibly from the max width tyres.

My other issue was riding the kerbs was hit or miss. Sometimes you would stick it, others it would lose it. Made the fast chicane on the back of the track tricky to hit right.

The car brakes really well. I found myself pulling up early quite a few times.

Have you tried less tyre, more power?

I have. What have posted here is my max grip tune.

Thanks for pointing out the centrifugal supercharger. It is supposed to be sport and I changed it above.

Thanks for your input, I’m gonna take it to the top gear test track and see if I can’t get rid of that understeer.

Ok DUST2DEATH, try this.

To get rid of the car being skittish over curbs requires a different setup but I’ll get to that in a minute.

First, here’s the changes I made to try to eliminate the understeer. The upgrades are all the same just the tune is different. I want someone to try it before I edit the post above.
Here’s the changes:
Camber) F: 2.4
Anti-Roll Bars) F: 20.0 R: 30.0
Rebound) F: 10.0 R: 10.5
Differential) Accel: 25% Decel 0%

Generally, I have different setups for tracks with a lot of steep curbs, like Yas Marina for example. But usually when you eliminate skittishness you sacrifice a bit of handling. So here’s the changes you’ll need to make to the setup.

Roll Cage: stock
Centrifugal Supercharger: race
Pistons: stock
Driveline: race

Anti-Roll Bars) F: 25.0 R: 35.0
Bump) F: 2.0 R: 3.0

Didnt like the above at all. It frustrated me.

While this rode the kerbs and had a little more power, I wanted the rollcage back. I just couldnt get through some of the turns as quick anymore.
Also when approaching the back fast chicane under heavy braking the car likes to bob for apples.
