I've just started building a gasser Rover P6, and wanting to raise the front of my Rover P6 by 6 or 7 inches. I'd love to sling a tube axle under there but it's a real budget build so for now i'm going to be raising it on the origional suspension. Thing is, i'm not too sure of the best way to go about it?
Don't know how familiar you are with the P6 front suspension set up but it's a bit of a perculiar arrangement:
Here's someone elses pic of their P6. Now, after a bit of a head scratch I can see 3 possible ways of raising it:
^ 1- The 'swivel pillar assembly' as the Haynes manual calls it, that vertical tube connecting the hub and top link assembly. This could be lengthened by the required amount yes? Assuming it's tubular and not solid, this could be sleeved and welded at the new length I thought.
^ 2- The ball joint that bolts to the top of the swivel pillar assembly. I was thinking maybe a flange could be made with a length of tube similar to the swivel pillar welded to it that bolts in place of the ball joint, then have another flange on top of the new tube for the ball joint to bolt to instead, and raise the suspension height that way?
^ Or 3- There's a rod thats part of the top link that acts on the road spring. If I lengthened that (or even threaded it and made it adjustable) that would also raise the suspension.
I discounted getting a longer road spring because they're already very long from factory and I don't think i'd find anything longer from another car. Although I suppose having some made isn't out of the question if neccesary.
So the question is guys, which way would you go about it? Any of the above? None of the above? A shorter version of all 3 modifications combined to get the right height? I suppose i'm looking for the strongest way of doing it really, the safest option. But if there's nothing to choose between them in that respect then the next consideration is the easiest/least machining/cheapest.
Here's what sort of suspension height i'm going for up front:
Hope you can help!
