Why tarmac stages follow almost the opposite rules to gravel: grip, line choice, braking points on a blind stage and the stiff setup that makes it work.
On tarmac you invert almost every gravel rule: more grip, a harder setup, later braking points — and instead of working with the slide you want to avoid it. The rule of thumb from the rally schools is simple: the grippier and harder the surface, the stiffer you can run; the rougher and more slippery it gets, the softer you have to be [3].
In setup terms that means tarmac runs higher tyre pressures in the region of 30 to 35 PSI, lower ride height and stiffer springs, so the contact patch stays stable and the car changes direction quickly [1]. Gravel runs the opposite — around 15 to 20 PSI, soft and high [1]. Two surfaces, two completely different cars, the same driver.
The mistake nearly every newcomer makes: treating tarmac rallying as circuit racing. It is not. On a circuit you learn a corner twenty times; on a special stage you see it for the first time at speed, in competition. So your line does not come from memory, it comes from the pace notes — severity, direction, distance, plus extras like "crest" for the brow where the car goes light [4].
Grip is higher and far more predictable. The car responds more directly, mistakes are punished harder, and the forces on tyres and brakes rise sharply. Where on gravel you deliberately let the car slide [2], on tarmac you want as little slip as possible — every slide here costs time instead of buying it. On tarmac, clean is fast.
You do not know the corner. So you build your line from the call: severity tells you how much to shed, distance tells you when it starts, and extras such as "square" or "crest" warn you about 90-degree corners and brows [4]. Drivers who get faster on tarmac usually get more accurate in the notes first.
On tarmac you can brake later and harder — but only as late as your information allows. Practical rule: brake so that the error points forwards. Braking early costs tenths, braking late costs the stage. Over a crest the car goes light and the brake loses bite — which is exactly why "crest" sits in the notes [4].
A stiff, low car rolls less, changes direction faster and keeps the contact patch stable — precisely what a grippy surface demands [1][3]. Run a gravel setup on tarmac and the car wallows, the tyre shoulder overheats and the late braking points become unusable. On tarmac, setup is not fine-tuning, it is the entry ticket.
More grip means more energy into tyres and brakes. On long stages the decisive factor is not the fastest corner but how much tyre you have left at the end. Run the first kilometres deliberately controlled, then build. The fastest tarmac driver is rarely the one who was at the limit earliest.
Everything here applies to special stages on closed roads and to closed training venues — never to public roads. Late braking points and limit lines on a country road are not brave, they are lethal and illegal. This guide explains and motivates — it never replaces certified driver safety and competition training, the licence course or instruction from a qualified coach.
Two technical safety points that weigh more on tarmac than on gravel. First, brakes: the higher grip produces more deceleration and more heat, so fluid, pads and lines belong on the checklist before every tarmac event. Second, tyre choice: a tyre wrong for the surface degrades fast and behaves unpredictably at the limit [1]. And third, what holds on every surface still holds: your safety equipment and the car's survival cell are the baseline, not the extra.
In testing, drive a tarmac stage once deliberately too slowly — with the single job of taking every corner exactly as the notes describe it, then comparing afterwards: did the call fit? That way you correct the notes instead of fiddling with the throttle. On tarmac, most lost seconds are not in the corner but in a call that arrived three metres too late.
Tarmac runs higher pressures in the region of 30 to 35 PSI, with lower ride height and stiffer springs for a stable contact patch [1]. Gravel runs the opposite: around 15 to 20 PSI, softer and higher [1]. The underlying rule: the grippier and harder the surface, the stiffer the car may be [3].
Not from memory — from the notes. Severity, direction and distance build your line, while extras such as "square" or "crest" flag 90-degree corners and brows [4]. Anyone who wants to get consistently faster on tarmac improves the call first and the driving style second.
No. On a circuit you learn the same corner many times; on a special stage you drive it essentially blind in competition and rely on the notes [4]. Add changing surfaces, real road edges and no run-off, and the cost of a mistake is on a completely different scale.
Because the recipe is inverted. On loose ground you deliberately work with the slide [2]; on tarmac that same slide costs time. On top comes a stiffer, lower setup with markedly higher tyre pressures [1]. The building block stays the same though: clean load transfer along the lift, turn, brake pattern [3].
