Is there such a thing as more than you need for brakes? Just need tires that can handle it!

Too much and you might hurt your neck. It's a safety issue, plus they kill momentum.

Adding unsprung, rotating weight to the car when it's not necessary isn't the best way to spend a buck if you care about performance either. One of the reasons I went with the STR40 instead of the ST60 was the cost was about the same but I got to drop ~12 pounds instead of 5. The 380mm kits do look cool though, and I bet on a street car that doesn't get tracked they'd go 100,000 miles

My buddy runs Pagid yellows and he seems to have made it down to min thickness much quicker than me.

^^^Judging by that car, looks like they definitely look like they don't know how to bleed brakes properly amirite?

I would think that they just used a front BBK in all of the tests seeing how I didn't see the rear wheels off at any point. Personally, I would bleed all 4 wheels if I just opened up even 1 line. But nonetheless...if I am right then I would expect Stoptech to perform the best. The others are probably designed to have an upgraded rear brake system. If that's the case then it would cause the front wheels to lock up well before the rear wheels and activate the ABS. From the video...ABS is clearly engaging in the one shot of the front wheel coming to a stop indicated by the tire noise.
ABS activation increases stopping distances. Let's look at Stoptech. They market their BBKs to provide balanced braking. So their BBKs are designed as a front only or 4 wheel kit. They aren't hesitant to let you know that they are the only company to do this and it provides a performance advantage. So if the Stoptech kit maintains a more optimal brake balance then the Stoptech kit should activate the ABS less and shorten the stopping distance. So Brembo owners and vendors can now stop the stream of tears and resume your normal Brembo superiority campaign (joke and sarcasm...all should laugh at this point).

I wish there was a translation of the article....fitting brand new tyres for each BBK initially seems to rule them out of the equation but are they scrubbing off a mm or so to square up the tread and remove any trace of release compound to make sure each set is identical? Plus tyre and track surface temps play a large role in how much grip the tyre can generate - are they measuring these variables?

ABS on modern cars (like at least the last 10-15 years) is able to keep the tire at optimum slip, or as close to that as possible. This is where friction is at it's highest and provides shorter stopping distances. Much shorter stopping distance and higher friction than a locked tire can manage... http://www.bosch-mobility-solutions....rochure_de.pdf |

The shortest stopping distance is achieved with a trained driver (usually a pro) doing threshold braking. That's how it's done in F1, for instance. For everyone else there's ABS.
We don't know if the car in the test is using a special ABS calibration. Most street calibrations won't get the best out of RComps or slicks, for instance. If you're running RComps and you have the right ABS calibration, you can pretty much do threshold braking - the ABS will hold off until things are well past that point. Street calibrations aren't so forgiving, and they'll kick in earlier. |
