On a road car you have to rely on 2 things to drive it fast :
- Mass transfers
- Optimal Slip angle
Practice your mass transfers, know when yo uget oversteer, understeer, and try to use them to help you drive the car : induce more oversteer when entering, and benefit from the understeer in exits to get proper acceleration.
Optimal Slip angle is the only way to drive a road car fast. While the grip on the slicks is either full or 0 (on or off, which a few border of limits), the border of the grip limit in the road tire is wider and dimmer than for a slick. Which means you can have more grip when you slide a little in a corner. Be careful, I don't mean *drifting*, but sliding, which implies that your 4 tires lose traction at the same time (not at the same moment).
It is easier to slide 3 of your wheels (two rear, and the inside front while the outside front is gripping to still have directionnal power on the steering) to begin with so that you can still go back instantly to a full grip if you don't feel confortable with it. The goal is to make your four wheels slide with the simple equation : front slip angle = rear slip angle. The optimal slip angle depends on many factors, especially whether the corner is tight. It can go from 1-2° in long and high speed corners, and can go up to 12-15° in hairpins.
The basis of this is to help carry the momentum of your car through the corner. This is quite entry-oriented, but it is mandatory on low-powered road cars when they are not powerful enough to have sufficient acceleration on straight.
Also, the slow in = fast out doesn't quite apply here for all of the cars. For some road cars : slow in = slow out (especially for the XFG and XRG), so the more speed you can carry in a corner, the more speed you will have at the exit. For the XRT or the FZ5, it is the opposite, because the turbo or the sufficient power can be a great advantage in the straights, then sacrifying some of the entry speed is mandatory to have a perfect exit line and power (put the pedal down earlier). If you compare the WR hotlaps of FZ5 and XRG, you'll see that the XRG tends to slide and have more speed in entries than the FZ5, which (because of its weight, layout and power) takes corners 5 to 10km/h slower, but benefits from its power in the straights.
So basically, each road car is different, but the slip angle and the mass transfers are mandatory techniques to overcome the small seals that are the lack of downforce and the tires limits
