T-3K Apex - Time Attacker 1.0

---

The T-3K Apex is an all out time attacker meant to break track records. Lots of aero allowing cornering of over 5G as low as 200Kph, with peak force as high as 9G in banked corners.

---

The car is mid-engine RWD, powered by a 1200Hp 3L V6TT, with a 4 speed DCT and it weighs 840Kg.



Aero load: 2500Kg at 150Kph, 4000Kg at 200Kph, 6000Kg at 250Kph, 7000Kg at 300Kph, 7500Kg at top speed (348Kph).

Notes:

This is still completely unedited export. Just 4.19 automation magic.

With the engine and chassis identical to the old car, all gains were made by the aero package. Flexible wings give this car massive downforce at low to mid speeds where it is needed the most, and gradually back off as speed increases to have less drag.

It is easier to explain by looking at the aero loads in comparison to the old car: +17% at 150Kph, +19% at 200Kph, +15% at 250Kph, -5.5% at 300Kph. The higher loading at low speed is measurable on the skidpad: T-3K Apex: 5.7G - T-3K Classic: 3.7G

Changes have been made to the tires which are now a lot narrower at the front (325 replacing 395), and the rear anti roll was removed completely. This is to balance the more forward-bias aero (up to 35% from 31% front bias).



Brake disk size is still something i had to balance to tackle length, frequency and initial speed of braking. Large disks are great for stopping from very high speed frequently, but they are a liability when needing to stop from lower speeds, being prone to lockup. So, it varies from track to track. I opted for smaller brakes to reduce risk of lockup.

All of this is an issue because cars like this need to be run without ABS to work, as going over 6G will trigger the collision auto-brake. ABS, ESC, even E-LSD will trigger this.
