Power:
BMS JB4 Stage 2 Tune
Flexfuel wires
40% e85 mix
any N55 FMIC, I like the Wagner as it fits without cutting anything.
any N55 downpipe, I have the BMS
any N55 intake, I also have BMS
any meth kit will also work
Cut out the midcats, worth 5-10whp.
There is a pretty bad kink (I mean, the pipe collapses to just about 1.5in diameter) near the rear of the muffler in the stock exhaust tubing, fix that for more slight gains.
Suspension:
KW v1 and v3 coilover kits exist
H&R springs are a bit cheaper
e9x camber plates work as well
A FBO X1 is capable of low 12s 1/4 mile with meth. I'm at 12.5 @ 110mph with no meth, stock midpipes and exhaust, full interior, and 19in OEM runflats.
Long story short, all the mods for the 135/335 work on the X1.
