Finally got diamond at Bathurst. Weirdly I find using BB forwards is better now because the last physics update made braking distances longer, and on a bumpy track such as Bathurst the extra braking force really pays dividends. It doesn't make the car understeer as much as expected.
Corner by corner tips:
- BB -5 except last chicane & corner -3
- T1 brake at ~90m. You don't have to hit the apex exactly here, I find carrying as much exit speed as possible and using all the outer kerbs are more important.
- T2 you can brake deeper than expected thanks to the uphill incline. Brake almost near the end of the asphalt sliproad on the left and then trail to apex. Avoid the inside kerb as it will unsettle the car. You want a slight 4 wheel drift to be fast here.
- I totally plebbed the Cutting on my diamond lap so it's not that critical to a good laptime. Just lift at the kink, brake straight and early, get as close as possible to the inside and accelerate carefully. Lewis is extremely fast in this whole uphill section and you can make gains later so just get through here safely.
- Quarry second part slight lift and STAY IN 3RD. For some reason this car understeers more in 4th gear
- First left kink is flat, second kink slight lift on the dip, third kink dab the brake over the crest and aim late apex.
- Biggest time gains for me are going downhill. You can absolutely go crazy on the Esses and cut very close on the inside at the Dipper. Can't give specific tips here, you just gotta learn the rhythm of the brake/throttle/gear. I find the more I think the slower I am so just let it flow
- For Forrest Elbow, slow down earlier and more than you think. I started lifting on the right kink before. Entry speed is really not critical. What's critical is getting as close as possible to the inside, rotating the car early and getting the power out.
- On the straight, upshift before going uphill so you don't lose momentum. Gains you a few hundreths easy.
- The chicane is my biggest problem until I learned a trick from Lewis - he lifts just before the 2nd brake board and then goes full brake after the board. That split second of coasting settles the car and allows you to brake harder and later. If you go full gas -> full brake it "shocks" the car and your brake distance is actually longer. Take a late apex, avoid the inside kerb and slightly delay acceleration. Too much power too early and you risk understeering off because the front end goes light.
- Final corner, same tactic as above. Lift before 100m and brake after. Late apex and avoid inside kerb. Use all the exit kerb and pray you've done enough. I beat him by just 0.003 sec
That's 6 down, 4 to go. Nurb and Brands 0.1 sec off. Suzuka and Willow still 0.6 sec off
EDIT: Got Willow to 0.3 sec off. I'm kinda getting the hang of the last corner but my main problem now is the uphill part of Omega. Car just doesn't rotate there. Surprisingly I'm plebbing Nurb GP so hard now. Can't get closer than 0.5 sec as I did before the physics update
