But if your engine is flat now, by raising the gearbox it won't be with the box raised?
Something to think about, also a 3" system will be that low too so speed bumps are never going to work for that car.
Sorry if I'm being a pain but you might do all that work and it's no better than it is now and cause other issues?
If your going to raise the box you would " benifit " from raising the running gear and keeping it square in the bay
Really I'm just saying I've seen stuff lower than yours and if it goes on a trailor it's not as bad as you think, I have too piss about to get most of mine on trailors and I don't have issues?
