Did some weighing:
Turns out
Stock 261M in 18x8.5 with 255/35/18 MPSS = 23.2kg
VMR V710 19x9.5 with 255/30/19 MPSS = 23.2kg
Not an error with scale. I triple-checked these. Just co-incidence.
So i guess tightening up my rear end with subframe bushings and altering camber to -2.0* has given me much more traction on rear? Because its quite hard to break traction in 2nd gear in a straight line, and slight to moderately difficult in 1st, from a roll that is. Used to spin like mad in 1st and break traction at 40km/h in 2nd prior to rear end mods. Logs show it's boosting fine...
. Will still check for boost leaks anyway, and maybe attend a dyno day and compare. Butt dyno says all is well though
Thats what matters most right?
