Hi Folks,
I've done some testing on the effects of brake strength, thought I'd share the results in case someone was interested. All testing done offline with DS3 controller. Sure, some of it is repeating previous testing by others on here, but I thought it best to start by checking whether the basics still work the same. EDIT: Test methods are below.
First up is straight line braking. The cars are Opel Speedster Turbo, Volvo C30R and Ruf Yellow Bird, all running Sports Hard tyres.
Next question, is what happens in corners? So it's time for some circuit testing at Tsukuba (unfortunately the Yellow Bird needed some crazy toe and ballast settings to stop flying off the track backwards). Here are my comments on the handling while under brakes
Ruf 3400S on Sports Hard
0 / 0 slight understeer, car "flops" into understeer mid-corner if releasing brakes while turning (a chassis setup problem)
5 / 0 more understeer, but smoother transition into mid-corner grip
10 / 5 most understeer, shortest braking distance, fastest lap
0 / 5 less understeer, more "flop" after releasing brakes while turning
Volvo on Sports Hard
0 / 0 mild understeer
5 / 0 dulled turn-in under brakes
0 / 5 gentle slide of rear under brakes
Ruf Yellow Bird on Sports Soft
0 / 0 oversteer everywhere (not just under brakes)
5 / 0 less scary
0 / 5 rear slides very easily under brakes
Ruf 3400S on Racing Soft
0 / 0 stable, outside front scrubs and overheats if turning while braking
5 / 0 more understeer, requires greater steering angle to turn while braking
0 / 5 rear slides under brakes, but car "flops" into understeer after releasing brakes.
Hope this is food for thought, I'm keen to hear what you folks make of these results.
Straight Line Test procedure
1) in offline practice, go to High Speed Ring backwards
2) MT, ABS 1, tyre/fuel off, grip reduction real, damage off
3) tuning: 0 ballast, LSD initial <15, LSD braking 5, default suspension except camber 1.8 / 1.3, sports soft tyres
4) coast to whatever speed you like just before the start/finish line (I used 230km/h except for the Yellow Bird which used 250km/h)
5) brake as you cross the line (helps to have a ghost to check you're braking in the same spot each time), do not downshift while braking
6) write down the grid position where you come to a complete stop
Cornering Balance Test Procedure
1) in offline practice, choose a track you are very familiar with (I chose Tsukuba)
2) MT, ABS 1, all other aids off, tyre/fuel off, grip reduction real, damage off
3) tuning: 0 ballast (use as last resort if car very unbalanced), LSD initial <15, LSD accel <15, LSD braking 5, default suspension except tune camber ( <2 for sports tyres and <3 for race tyres), rear toe (-0.4 to 0.3) and springs to achieve neutral balance for baseline
4) run laps, paying careful attention to manouvrability/stability while braking, how the car responds to gentle dabs and the chassis response as you release the brakes.
