    This car is not a peach. It is a precision instrument, and will be used as such.

    # Laguna Seca 2019-04-20
    
Earlier in the year, I signed up for Laguna Seca HPDE hosted by SpeedSF on 4/20. This would mark my first HPDE in over 3 years and my first HPDE in the E90. It was safe to say, there was a lot of rust to clear up! In hindsight, I should've done a track day in full stock form but oh well!

    Current setup:
    MCS 2WNR Coilovers
    BBS GT4 on 275/35/18 PS4S
    PFC08 brake pads / Castrol SRF
    BW SS brake lines

    The weather in the morning was definitely not behaving as the morning sessions were a “tad wet.”


    Open 2 group was the first ones out which made it more fun! Lap times were ranging in the 2:10.xxx mark during this session simply because it was so slippery.


    Luckily by lunchtime, the weather started to clear up and I was able to get some decent laps in. I finally was able to get into the groove by the last session of the day.

    ## Impressions
    MCS coilovers were simply amazing. Since this was my first day out with the car, I was more focused on fine-tuning the nut behind the wheel before fiddling with the setup too much. At the end of the day, I felt like I was in a great position to improve times without fiddling with the setup too much.

    I ended up setting the MCS to the following settings:

    Front
    Rebound: 16 clicks
    Compression: 6 clicks

    Rear
    Rebound: 14 clicks
    Compression: 6 clicks

    It is not set in stone but I still need to fix the driver before I can start fiddling with the suspension more.

    The Michelin PS4S tires were great but definitely not ideal for a track day. They did perform great in the wet whereas the folks on NT01 were having a hoot in the earlier sessions. I felt like I was getting them greasy at the end of the afternoon sessions even at my slower pace.

    Brake pedal feel was okay and the PFC08s were not warming up enough for the first few laps (Another telltale I was too slow for the car) and squealing. They definitely were powerful enough to activate ABS on the PS4S so that was a good sign they were doing their job.

    ## Video


    I started to fiddle with RaceRender and it's been really cool to throw in Harry Laptimer data and GPS data from the GoPro Hero5 into the mix. It makes a very cool compiled overlay with a decent amount of information. If HPDEs become a little more serious, I will "invest" into an Aim Solo2 DL. For now, this will do pretty well!

    Lap Time: 1:47.11
    I am happy I was able to at least get a 1:47! My old E46 was doing 1:49s so I was hoping to save face by at least beating my old slower car. :lol:

    My quick analysis says I was early apexing T2, T3, early braking T5, early apexing T8 to name a few obvious areas needed for improvement. I saw one of the M3post members Kpewpew was doing 1:42.xx so I have a few ways to go once I have some better tires.

    Next HPDE will most likely be in the summer months so it will put a test to the brakes and PS4S. I'll run the PS4S until it wears out and purchase one of the 200 treadwear tires to replace it.

    That's it for now. Till next time!

    That audio is way too good for a GoPro. Did you have an external mic?

    Ahh yes. Audio Technica MTR3350 external mic right below the rear license plate area.

    That video is proof the e9x was the best generation M3. There will never be a sound like that from any Bmw going forward. Damn.
