Scrub Radius: From my observations of other cars, the 75 has a fairly aggressive scrub radius. The SZ/RZ even more so

Apart from load on the steering components, what other disadvantages are there from having a high amount (for a road car) of scrub radius? I see many cars with much lower scrub radii.
This brings me to my second (rehashed) query:
Increased Track Width: With a decent camber curve, I have enough negative camber gain for the front tyres to clear the top of the wheel arch even if I add 20mm spacers behind the wheels I have.
Coil Overs: I would ideally like to go a pure coil over set up and ditch the torsion bars.
So my current thoughts are:
To make new wheel hubs that reduce the scrub radius. I recon I can move the wheel mounting flange in by between 12-15mm with the wheels I have, before I have clearance issues with the brake calipers.
Make new upper and lower control arms that allow for not only the reduced scrub radius of the different wheel hubs, but also increase the front wheel track by a total of 40mm over current. At the same time remove the need for torsion bar splines (not really an issue) and move the lower ball joint forward to give more positive caster without clearance issues.
My desired move to a stand alone coil over set up raises a question.
I would like to use a 375lb/in coil spring per side. Nothing massive, but technically the chassis isn't designed for it. Apart from my viewtopic.php?f=10&t=3403, which I believe would be sufficient, do others see any potential long term durability issues with the chassis and a pure coil over set up?
