  1. CH1: Welcome to the family, Betty

    You must be wondering, why are you seeing a brand new 2016 BMW (F80) M3 sedan next to some of the coolest race cars in the world on the JRZ website? And why is she named, “Betty?”

  2. CH2: The first of many for Betty

    Later that very same day, Tom drove over to Blacktrax Performance in Milpitas, CA with a tank full of 91 octane Shell V-Power gasoline to find out just how much power “Betty” is putting down at the wheels using a Dynapack dynamometer. Keep in mind, BMW claims that the F80 M3 produces 425 horsepower and 406 ft/lbs of torque at the crank.

  3. CH3: Betty gets big gir shoes and shocks

    In the last chapter of our blog we wrote about how Tom had his first-ever track day with “Betty” at Thunderhill Raceway. Since then, the team here at JRZ Suspension Engineering has built a brand new set of RS Two Touring dampers and shipped them out to sunny California for Tom to install and use. As it turns out, Tom had been very busy preparing for these shocks to arrive.

  4. CH4: Betty goes back to the track

    In order to solve this problem, Tom chose to partner with our friends at Fall Line Motorsports to run their cleverly designed rear toe link kit. These allow for the rear toe to be easily set after camber is adjusted. This meant that Tom was able to dial in the rear toe to his liking in order to minimize any “rear steer” while still maximizing rotation.

  5. CH5: Betty unlocks even more potential

    There’s never a dull moment with Tom Tang and his 2016 F80 BMW M3 6MT sedan, “Betty.” With the end of the year quickly approaching he wanted to accomplish at least one more thing before 2017 arrived; and that was to lap Buttonwillow Raceway in under 2:00 minutes on street tires. Not an easy feat, especially for a full street weight daily-driven car with no aero. However, Tom knew that he and “Betty” could achieve this personal goal.

  6. CH6: New shocks for Betty

    The new RS Two shocks shipped from JRZ’s global headquarters in the Netherlands with updated packaging that I personally think is a much better representation of the quality product(s) inside. They arrived at Trackspec Autosports in Fremont, CA. Trackspec are my partners this year, and they are now proud JRZ dealers and authorized installers.

  7. CH8: "Betty” receives the world’s first ever set of 095 edition JRZ RS PRO3 dampers

    Hi, everyone. Tom Tang, here again. Recently, JRZ released “095 edition” dampers to commemorate the first-ever JRZ shock designed and developed by company founder, Jan Zuijdijk, back in 1995. The “095 edition” dampers are available in two trims: double adjustable as the RS PRO, and with the addition of low-speed compression as a triple adjustable shock in the form of the RS PRO3.

  8. CH7: Betty joins the sub 1:40 club at Laguna Seca

    As a longtime JRZ partner, I was honored to be chosen as the recipient of and test driver for the world’s first ever set of RS PRO3 dampers; built for my 2016 F80 BMW M3 6MT, “Betty.”
