I got this email from my local dealer, aug 27th.
Hello i4 Depositors!
We have some fantastic news!!
We were finally given our i4 First Edition Allocation.
i4 FE Production begins in January 2024 and will last for four months. Deliveries will begin most likely beginning in June.
I would avoid those and go straight to Castrol srf, track compound would depend on how aggressive of track driving you want to do.
best choice is swap pads from race pads to street pads depending on the occasion.
