For a second time, my friend Chu, kindly offered his M2 to me to take out for a session at Sonoma. Similar to Laguna, the intent was to get footage and data for him to review. This is a 2017MY OG M2 with the N55 engine. There's 1-2 seconds more left in the car with me driving it in its current setup. This was the last lap in the session and I was forced to take a critical long corner, slower than I needed to.
My feedback was that air pressures needed to be dropped by 2psi and I think that really helped to make the car slightly less nervous.
Chu's F87 has the M4 GTS tune for steering, transmission, and stability/traction programming, Apex Wheels with 265 width RT660 (2022 clearance tires), stud conversion, 2-way JRZ RS Pro (purchased used and rebuilt by Elite Performance), Ground Control camber plates, and ride height remains stock (very close to it at least), Pagid RSL29 brake pads with Castrol SRF Brake Fluid. Car has a full interior and I actually found the stock seats to hold me in decently well once the side bolsters were fully inflated.
Great fun!
