This is built from the earlier donk version of the kit, but the lowrider front and rear ends were on the sprue.
I used them, redrilled holes in the front suspension uprights (or made new uprights, can't remember which) to raise the front a little bit.
For the rear I inserted spacers above the rear end and carefully bent the trailing arms to fit the new axle position.
If I was to do it again, I wouldn't raise it quite as much. :)
Easy job, anyway.
