Now that you mentioned torque, would a stock GSR that's overboosted 1.0 bar with locked 4wd autobox be able to produce more than 35kgm or 350nm? Don't think it's possible, isn't it?
Your autobox is from GSR? It comes with eco/power mode? What would the eco/power mode do? Does it delay the gear changes in power mode to a higher RPM bandwidth and vice versa with eco mode? It'll be great if you can share a little on the autobox twerks.
Also, I don't think stock GSR can go beyond 180 due to speedcut, isn't it? Pivot, RSM, or some form of speedcut alteration device is probably required. I'll probably do it too once I have GSR swapped in my Wira.
In this case, I'll need 6k spring rate for front coilovers due to the autobox? It's that heavy ke? Oh my.
I live at Kota Kemuning. Is it near to AEON Bukit Rimau by any chance?
