My suggestion for all S tests is simple (except from 1): Take every turn at one gear higher than necessary, and manage the throttle wisely (if you find it hard to take them at the 'recommended' gears, that is).
Saved me lots of trouble, I'd only get out of the track because of my dumb mistakes
S1 - Can't really give you any tips on that as I barely got 1:46.7-ish after LOTS of tries. Not sure what I was doing wrong there.
Barely hit the gold here after well over 15 tries... ashaming 1:46,700 :C
S2 - Got it after like 5 tries, with each one failing a bit later than the previous one.
The first turn doesn't require that much braking. Same applies for the second and final turns, but the final one gets narrow, and you might accidentally overshoot it as you are about to get proud of your amazing time when you're practically on the final stretch already. The final turn is easier once you realize that it turns into a straight for a short distance - it makes it easier to brake in the right moment!
That winding section might be kinda tough, especially if you're under pressure of the IMUSTGETGOLD factor

Take it easy, and if you're having trouble getting through it at 2nd gear, use 3rd all the way there, but still watch out at higher RPMs!
1:26,272 - relatively good by my standards. Cool test as it allows you to practice fast corners.
My god the TZ3 is gorgeous
S3 - VERY easy and fun, actually. The X-Bow's low weight and power makes it fearsome in turns at first, but once you get the hang of its abilities, you'll love its agility (of which you also have to be aware!)
Launch from 2nd at full throttle, as launching from 1st and switching to 2nd takes about 1/4 of a second off your time., and is simply slower to begin with. Anyway - as mentioned, keep using the 3rd gear in all turns, as it's almost impossible to spin out even if you exit the turn at full throttle. It's letting off the gas that gets you - you might lose control if you take the turn without 'throttling' at all.
This test is 0:54,924 of pure fun, be careful of the X-Bow's agility, if you take the turn too slow, its insane grip will make you shoot straight at cones.
S4 - I'm not that good at Brands Hatch, but I think you can use the LP700's weight and 4 wheel drive to your advantage; slightly throw it around tighter corners. Since it's a 4WD and mid-engined, you might be afraid of spinning out. Don't be, the Aventador is very agile and graceful in this test, but remember it likes to understeer as you exit corners at full throttle.
The first turn of Brands Hatch sickens me, I just don't know how not to go off the track there. The second turn is relatively easy to drive through, but as you approach it it's very easy to brake too late and overshoot the corner. The next turn is simple, just be careful and remember that you can use its exit curb to your advantage - there are no cones there. The next one is far faster than it looks, but don't overdo it on the throttle - Aventador likes to understeer. As you near the end of the straight before turn 5 (the one before which you go downhill and uphill for a bit), don't be afraid of speed, it's actually a pretty fast turn. The next one has a strange apex, and you gotta watch out for cones, too. The next turn only looks slow, go for a wide apex (similarly to that LOOOOONG first turn at Apricot Hill) and then dive into the green inside curb. Watch out for your braking before that one too, it's easy to lose control over that beastly Lambie when you're braking, also because you can't quite see the apex because of the peak of the hill this corner is on. The next turn is closer to the previous than it seems. Brake earlier and dive to realize you took it too slow (happens to me every time, not only during this test)
Not the best time, but still managed to gold it with 1:34,209.
S5 - now that is one hell of a challenge. Your throttle management will get tested the hell out of. At first, get used to Veyron's complete inability to turn on Sports Hard tires, I think that only Buckingham Palace understeers more than that thing.
You will absolutely hate Ascari's sharp turns with little room on their exits. But once you gold this challenge, you'lll love its sharp turns with little room on their exits.
Use the 3rd gear for every single slow turn here. No exceptions. Be extremely careful in corners, as even a slight overdose of throttle can make you go unbelievably wide. Once you're on the straight leading to that chicane, congratulations - the difficult part is over! Be careful though - the second-before-the-chicane turn is not as quick as it seems!
The final turn seems easy. Before it, get as close to the left side as possible, being extremely careful not to even scratch the grass, or you'll lose precious time or even fail the test completely because of trying to stabilize the car. Dive into it at 4th gear, with your throttle about halfway in, gradually increasing it as you near the exit, and thus the finishing line.
2:11,767
I failed this challenge twice right before the finish line, how mad I was should get documented.
Remember - 3rd gear is your savior in this challenge!!!
I hope you can understand my complicated explanations, and I hope this helps at least a bit.
Good luck!
