can someone please advise on a good ride height for the inboard vortex,also where to measure from.

im not sure what it should be, but my indys at about 110mm at the front...not sure about the rear...
that was for sva...

I think my MNR is set 100mm at the front and 125mm at the rear

Front ride height is set when the front lower wishbones are parallel to the ground. Rear ride height is 25mm higher than front ride height measured at the front of the rear wheel arch.

also depends on how low your sump is... my zzr sits an inch lower than the frame and have had to raise the car...

20mm difference between the front and rear at the front suspension mount point and the rear bulk head respectively..
