I just wished PD would've given us a universal BB setting for each car in the game so that way we don't have to figure it out ourselves!!
Sorry I just have one more question regarding BB setting. So if I use a BB setting for a car using one type of tire compound like Sports Medium, would it still be the same BB setting if I switched to a different tire compound like Racing Hard or Comfort Soft? For a stock Ferrari F430 on Sports Hard tires using a BB setting of 5/2 would still be using 5/2 if I switched to Comfort Soft tires?
That is a very good question my friend, tire compound will influence the braking balance of a car, although the degree of influence is not the same on every car or layout ( FR,FF,MR,RR) An example : I can run Cizeta V16T stock on comfort medium using BB 9/7, but on higher grip tire like sports or racing tire, I would have to adjust the BB again to get the best out of it. The Ferrari F430 stock, I am using BB 8/4 with CS, then with SH BB would be around 8/5, it will also depend on the driver ability to modulate and the controller used, higher BB will always need more delicate braking and better modulation. The higher the grip of the tire, the better is the braking performance, so you can lower the BB to get higher threshold of braking pressure before locking ( if you find modulating at less than 60% difficult ), but the limit seems to be broken more sudden on sports or racing tires.
Higher grip tire = better braking performance - lower BB can be used to achieve good braking - generally higher pressure before locking.
Lower grip tire = lower braking performance - to compensate use higher BB numbers, needs to be more delicate, ie : 9/7 - tire lock up after 50% brake used.
I'll give a nice trick to tune the BB setting, run the car at Tsukuba, Motegi Road or Fuji, but you can always try this on any track you like. Disable tire wear for testing.
1. Run BB 10/0, do several high speed and low speed braking, do the best as you can, take a note of percentage of brake bar when the front tire start to lock up.
2. Reduce BB at front, while rear at 0, until you find the front less prone to locking at braking pressure that you are comfortable with.
3. Lets say you have 6 front, now increase rear to the same number (6), then try on the low speed and high speed corners, try to trail brake late, and the car will start to tail out easily. Lower the rear one by one until the car give the car slight understeer or oversteer on late corner entry to suit your taste and driving style. Remember you can brake in corners, but it needs to be very gentle ( 10% of brake pressure at most )
Another good sign when to eased off the brake is when tires about start to become red, the squeal gets louder, or the car start to squirm/losing balance with high rear BB number.
I've posted this before, but for comparison to most ABS users, I posted the Academy Seasonals TT with bone stock GTR Black Edition GTA- 541pp, 526hp, 1730kg, using CS with BB 9/6, a very high number, this allows me to brake late and better to compete with ABS driver, my time was 1:58.286
