I know their crazy spec safaricomp racers, but since i'm not competing I think the look could be done and still be able to do some gentle green laneing, I don't want just a padock car, small point to remember I'm useing rally gravel tyres which are much lighter then pretty much any 4x4 tyre
if your planning any green lanes at all (by green lane i mean legal byway - not bridleways, footpaths, fields etc) then you need ground clearance under the car, adding bigger diameter wheels will only give a little lift under the car itself before things bottom out
I run 31" diameter rims on my 4x4 and still catch the wishbones/bottom mounts on local lanes...
Cracking idea tho and I've been thinking about jacked up cars recently too, only a couple of inches, high could defo be the new low!!!
