As strat mentioned, the cause of the instability is probably the difference in pad friction coefficient between the xp10's and ebc yellows. Try matching pads front to rear.

You can do it on rural roads if careful.
100-10kmph 10 times over like stated in the post above. I do it all the time prior to track. Do it at your own risk. The layer wears off on the way home... I would never attempt it on track unless is was closed lol |

The only thing I did to bed-in the pads was to avoid hard braking (with ABS) during the first 200km of city driving. It seems I keep doing stupid things
After that I left for the mountains and I really pushed them hard the whole trip. Then I hit the track and the rest you know. I have a 80km drive to the nearest track with about 40km of highway in the middle. I'm going to try re-bedding them on the highway on my way to the track next saturday. Meanwhile, here are some pictures of the rotors, looks good to me and the surface feels very smooth and plain. |

In my division, SM times are competitive with T4, so that really didnt sound right to me. So I looked it up: Sonoma SM: 1:54.9 86cup stock: 2:00.8 Laguna Seca SM: 1:45.5 86cup stock: 1:48.6 Willow Springs SM: 1:36.1 (2016) 86 cup stock: 138.6 Not that those results are anything to be ashamed of for a car on street tires, SMs are actually very fast. It takes 86cup modified class to beat SM records at Laguna and Sonoma. |

Hard to beat a Miata on Hoosiers with street tires and an extra 500 lbs, SM records should drop next year as they start using the Penskes, 86cup will drop too as people get more experience building to the ruleset, not a great comparo since fast tires get punished so hard, stick R7s on an 86cup Stock class car and I would bet on the 86.

That being said, if we have the fast guys run stock class cars for times, I can 100% assure you the SM times would be beat. These "fast guys" would be T25 winners, pros, etc. They simply choose not to be big fish in small pond, at what is essentially a friendly competition. |
