Hello, all!

It’s been a long, long time since I’ve posted anything in the Tuner’s Lounge, but I’ve come across something that I’d really like to share! o2R Dsquared 07 was running great times in his 458 in a lobby one day, and I immediately noticed he wasn’t using any Forza aero! I gave him props for doing so, and he asked me to tune one of my own. Here’s my shot at his request:

PI: 700
Power: 650 HP
Torque: 484 LB-FT
Weight: 2,800 LBS
Front %: 44%
Displacement: 6.0 L

Speed: 9.0
Handling: 6.3
Acceleration: 9.0
Launch: 8.1
Braking: 6.2

BUILD

Platform and Handling
Race Springs and Dampers
Race Front/Rear Anti-Roll Bars
Race Weight Reduction

Drivetrain
Race Driveline

Tires and Rims
5Zigen GN+ Rims

Conversion
V12 - Enzo Ferrari Engine Swap

IMPORTANT: “Wait, this car is at 703 PI! What’s the deal?” Don’t fret, we’re going to employ the aspiration trick to get the car down to S class. First, purchase the Twin Turbochargers under the Conversion section. Next, buy the Race Twin Turbochargers in Engine and Power, and then sell them. Finally, buy the Street Intercooler. This adds a useless intercooler that adds absolutely no power but adds 44 pounds to the car, making it heavy enough to drop to S class.

Note: Race Brakes and Race Differential come stock with this car.

TUNE

Tires
Tire Pressure: 29.5/30.0 PSI

Gearing
Final Drive: 4.58 - A humorously effective setting.

Alignment
Camber: -0.8/0.0
Toe: 0.1/-0.1
Caster: 1.0

Anti-Roll Bars: 18.80/21.90

Springs
Spring Rates: 569.5/981.5 LB/IN
Ride Height: 5.6/3.9 IN

Damping
Rebound Stiffness: 7.9/7.3
Bump Stiffness: 1.0/1.0

Braking
Balance: 41%
Pressure: 190% - Set extremely high due to no aero - can be adjusted to preference

Differential
Acceleration: 53%
Deceleration: 5%

So far, this car’s best tracks seem to be Road America, Hockenheim, Indianapolis GP, Sedona, and the Nordschleife. I’ll update this with a few lap times from myself and other drivers soon.

Well, that’s about it! The tune is also on my storefront if you don’t want to build and tune it, but this thread will be here if you want it unlocked. If you get it from the storefront, please rate it! Cheers.

Hmmm I will have to check this one out. As a Ferarri fan, I run them more often than not. Can this same build be applied to the Scuderia as well? Base PI is only 3 higher.

You can’t have the engine swap and race weight reduction with the Scuderia, unfortunately. I don’t think it’ll do very well without aero, anyway. But if you get something to work with it, let me know!

Thanks for posting this Bulin - having never tried the “aspiration trick” (great explanation BTW) I will have to give this a try!

Oh, just seen you’ve throw this on the TM. Nice 1. This no aero 458 might just be my favourite ever car in Forza 4. So much fun and so nice to drive. I must apologize as I’ve only run a few laps in your setup so far. I’ll give it a proper run at some point today. See how it compares to my own. Since you’ve open sourced it, i can maybe try a super tune combining both of ours. Unless you’ve already perfected it. Your tune does look quite a bit different to mine. As far as I’m aware, i discovered this build and it’s great to make the 458 genuinely competitive.

Also, LOL at the final drive. Great stuff

Feel free to do what you like with it! I’ve been messing around with super low camber in the rear lately with cars that don’t have stupidly fat tires, and it seems to work for me, especially in R3.

What is the significance of raising the front ride height in relation to the rear? I’ve seen a few people doing this. As it happens, in my 458 the front is higher than the back but that’s only because i didn’t i didn’t alter them from default. I’m using your final drive, mind. I like those gears.

Well, the initial idea behind the front ride height thing was to allow more air flow and give the car a hair more acceleration, but when coupled with soft front springs and stiff rear springs, it lets the car dive in a bit more without having to rely on other settings to get the car turned in. It’s not particularly plausible in real life, but it works here.
