EBC BSD series high carbon rotors and StopTech 309 series (para aramid) brake pads. StopTech also fits the 309 series pads in the StopTech Big Brake kits, but as I drive relatively conservatively, I do not plan on many 120-to-dead stop braking adventures that require all those extra pistons in...

That story has circulated widely, but it is misinformation. Walmart is closing TWO underperforming stores in Portland, one on N Hayden Island Drive in an industrial area just south the Columbia River, and another in a hard to access location off of SE 82nd Avenue, on March 24. Neither of those...

Carroll Smith, for years a Consulting Engineer for StopTech (now a part of Centric Parts), knew more about all of the arcane aspects of automotive braking systems and their components than any other human who ever has lived. He was the author of this article...

You join some famous company. Dewar's White Label was the favorite beverage of former Attorney General of the United States (and, later, federal prisoner) John Newton Mitchell in the late 1960s and early 1970s. (One suspects that his consumption of Dewar's was cut back during the 19 months that...

Of course, when it comes to matters of taste — well — de gustibus non disputandum est. As one who in the past year has (depending on how one counts age) embarked on my ninth decade on this mortal coil, i have consumed one, and sometimes as many as two, cup(s) of freshly brewed coffee about 360...

Good luck finding Mobil 1 ESP. The same oil has been re-branded Mobil 1 Euro now.

Got to it this morning. The two dry boiling point = 522° F. bottles have a date of 9.5.22, which in the U.S. usually means September 5, 2022, but in France, where the bottles were filled, it could well mean May 9, 2022. The dry boiling point = 516° bottle reads 11.06.21, which means either...

We have a passel of bad experiences with Bosch, although mostly with mechanical devices, not with fluids. We had a terrific, powerful Bosch countertop blender that worked for a while, then one day the connection between the container and the motor base started spinning uncontrollably; turned out...

One of the three 500 ml bottles was emptied (into the vehicle) by the mechanic who performed the new rotors and pads installation; I'll take a look at the other two when I get a chance to go out to our garage

I looked, but the date code, if any is effectively invisible; the Motul bottles are charcoal grey plastic, and the date code would be black on dark grey.

We are in the midst of a brake upgrade. Two years ago, we bought a ten year old Infiniti EX37 Journey AWD, with 38,000 miles on the odo. which, according to Carfax, had been serviced exclusively at Infiniti dealerships for all of its service life. (And the previous owner had anticipated service...

Originally Posted By: y_p_w I don't have an issue that you mention that all-season tires as a class tend towards slightly worse wet traction performance than summer tires. That's pretty obvious because the performance can be measured. I do have an issue that you attribute this to water adhering...

Originally Posted By: y_p_w That wet traction is improved by a tire where the tread holds onto some water and has been known for a long time. Here's an abstract of a technical article from 1956: Quote: So maybe the authors from these sources are off their rockers - especially the material...

Originally Posted By: y_p_w Just as a follow-up, read the literature on why silica is added to tires. It improves wet traction BECAUSE water adheres to it. This is a pretty good explanation of all the factors that go into wet grip: http://www.continental-tires.com/www/dow.../CSC_5_grip.pdf...

Originally Posted By: y_p_w Just as a follow-up, read the literature on why silica is added to tires. It improves wet traction BECAUSE water adheres to it. That many summer tires with high silica perform well in the wet is partially because of the high silica and partially because of other...

Originally Posted By: y_p_w GC4lunch has been mentioning . . . that all-seasons are designed for water to stick to the tread and that the ideal tire for wet would be rubber designed to shed water. The first part of what you paraphrase is true; the second part is your own fantasy and quite false.

Originally Posted By: y_p_w It's 2013 now. Yes, but the calendar has not altered the physical properties of water. Originally Posted By: y_p_w Similar advances have occurred in tire design technology. If you take a state of the art performance all-season today, it will likely be quieter and...
