Published on 08 Feb, 2024

Dropped 4 seconds since my last outing at BW, pretty happy with that but definitely can be improved. Hopefully next time out I can at least match or beat my overall PB (2.07.3 in a MK7 GTI).

Fair amount of traffic this day with Turn8 but was able to get plenty of clear track during the final 80min open track session.

Major changes included Megasquirt 2 and tune (124whp) and narrower tire setup (15x9 225 Nexen Sport R to 15x8 205 Kumho V730) the narrower setup feels a lot better and more responsive for some reason. Maybe I just prefer Kumho V730 over Nexen Sport R.

Setup:
205/50/15 Kumho V730 on 15x8s - Hot pressures 30PSI
MeisterR Clubrace coilovers
JDM BP5A, NB2 headers, 2.5" catback, ebay intake w/ heatshield/airbox
MSPNP2, tuned by Toby at Advanced Engine Dynamix
FM sways (loosest settings)
R1concepts track pads front, sport pads rear
