Un article de LFS Manual.
These cars are mainly for racing against each other with the same car, as they don't fit in any of the other classes available in LFS.
LX4
Short: LX4
Moteur avant, propulsion
Moteur: 1.3 litre - 4 cylindre en ligne
Puissance: 105 kW (140 ch) @ 8212 tours/min
Couple: 131 Nm (97 lbft) @ 6917 tours/min
Poids: 499 kg (1100 lbs)
Rapport poids/puissance: 210 W/kg (286 bhp/ton)
Distribution du poids: 45.8 F 54.2 R
Capacité du réservoir: 40 ltr
Tipping the scales at a mere 499 kg, the LX4 is a pretty light car and is quite fast around the twisted S1 tracks. Compared to its bigger brother, the LX6, the LX4 is easy to drive and ideal for beginners to learn how to control a LX-style car.
Conseils: These LX cars need a fair amount of understeer in the springs to keep the controllable. Don't go silly with the spring rates though. Low tyre pressures are needed. Keep the diff as open as possible on the power side and reasonable well locked on the coast side. Some rear toe comes in very handy here.

MRT5
Short: MRT
Mid engined, rear wheel drive
Moteur: 600 cc turbocharged inline 4
Puissance: 48 kW (64 ch) @ 7894 tours/min
Couple: 69 Nm (51 lbft) @ 5071 tours/min
Poids: 221 kg (486 lbs)
Rapport poids/puissance: 217 W/kg (296 bhp/ton)
Distribution du poids: 37.5 F 62.5 R
Capacité du réservoir: 20 ltr
Based on the real MRT5 built by the McGill Racing Team and competing in the Formula SAE championship this lightweight car is ideal for autocross tracks and slow configurations. The MRT5 is fun to drive and reminds you of a kart although it has more power and a differential. See the official website.
Conseils: This car is best with SOFT suspension. Understeer is certainly not needed in the springs, it hurts turning too much. Just adjust antiroll bars to get the balance you want. Also, this car is extremely sensitive to differential settings. Use the viscous differential and keep it fairly open (low single digits). Very low tyre pressures. Rear toe comes in handy again here.

Le véhicule le moins puissant mais pas le moins amusant. En fait, on rencontre les courses les plus serrées avec cette voiture. Cepandant, elle est inadaptée aux circuits rapides.
Conseils: * Des amortisseurs plus durs permettent de compenser l'absence de barre anti-roulis et aident à mettre les pneus en température.
- Surgonflez les pneus arrières pour compenser le sous-virage.
