the sway bar doesnt really do much to a standard vitara. you might notice it a bit on road, but no one seems to care.
you can remove it and still be ok with drive train component issues. i took mine off, gained a little bit more flex from the front, but i still didnt break anything.
if you want, you can gain an extra 1" of droop if you flip the strut top mount. this can almost be safely run also, and with out thrashing your trucklet too much, you will survive.
the only time i broke a CV was when i put in my strut spacers. at full droop, i can start to feel the CV balls binding, this is not good if the sus is at full droop and the steering turned at any angle. you are pretty sure to spit a CV.
even now, i havent been through a CV as i have adapted to driving my vit a certain way. i sacraficed a bit of go pedal, but gained with more sus travel (rear) and a rear locker. i havent done any major damage yet.
hope this helps, and have fun.
Cheers,
Steve
