Btw - nice axles.

The portal offset gives 100 mm lift, then there is additional lift from tyre diameter.

I have air springs and had intended to run standard suspension height on normal roads (my controller has 2 ride heights that can be preset and also active cornering/dive control over a set speed).

I don't believe the revised rules will be relaxed much, not enough for what I had.

I would not have any problems with stability, braking or handling - extra track width, a lot of measures to keep C of G low and reduce weight (particularly in front and behind F/R axles), hydroboost brakes, decent sway bars.

I would not be in any more danger in the event of a collision from changed height of impact protection. But the height of impact damage on the other vehicle is what I see as the big issue with VSI50 and I don't think this will be relaxed much.

When the dust settles and the new regs are known, I am hoping that I may be able to modify the chassis to raise it where the axle bump stops are.

This would overcome the lift due to the portal offset, but some thought will have to go into the suspension link mount locations for good link geometry. I may have to modify the engine sump to clear the tie rod (I have a tripple section scavenge pump, so could make it dry sump as a worst case).

I am not concerned with suspension height offroad as I can easily lift it 100 to 150 mm there, and still have good down travel (356 mm total travel at my shockies is subtantial at the wheels).

However if I was to continue the build with the greater freedom that the portals allowed, I would have much more work to undo if I had to take them out.

They are Nissan GU axles with Marks portals. H233, diffs with ARB lockers.

John have you actually had a chat to an engineer? even if the VSi50 had come into play people building cars where still allowed to finish there products it was just a matter of talking to an engineer and have him sign off I think on the work that is in progress to be done. I.e just to prove ti was being done before the date.

and I think it was to get lodged with the light vehicles man at the RTA so when time came to register they knew about everything before hand
