As Bill and James pointed out there are a few ways of doing it,
I find one of the best ways is to mock the body/bed/and frame up. set it on a stack of cards and adj the height. With wheels and tires chosen put them under and start playing the cards. Once you have your stance chosen, then start looking how low your going.This will determine if moving axle mounts or more surgery will be needed. Another way is to kitbash a whole new frame/ powertrain and fit things in
On this Cameo I used the frame/suspension from a Z06 vette
On this Nova the spindles were cut and moved up:
on this Elky both front and rear axels were adjusted up:
and if you want to see a massive frame Z job.....all3 of these frames were Z'd:
on this 32....the first one is stock front height, the second shows a Z up front.
so heres some ideas for thought .....now get cuttin!!
