at the moment im running both MRCG and sinister,both are very different in terms of handling.
my sinister has had alot of work to make it suit me,the front suspension left alot to be desired,stock out of the box not as good as the mrcg but with certain tweaks it can be very competitive.
the MRCG is alot more responsive with the rear suspension setup,there is alot of adjustments to be played with too but once you find the sweet spot its unbelievable to drive,a different animal all together
all the tgr stuff i have left is:
most of the different camber castor bars
disc damper setup(only one left)
front spring kit
set of kingpins
not tried the p28 yet but i do plan on getting one to compare when they are made available
