Thorney,Here are your choices:
Spax - adjustable and available now, used by a few here.
Nitron - I'm testing a kit in 2 weeks time to see how they are.
Vauxhall - Sprint kit will be available, but you're right it cold be a while.
The adjustability I will be looking for is in geometry, not the damping.
Toe, Camber, Castor.
I would think that the adjustable components fitted to the VX Sprint will have these fitted. Where abouts was your house again ? I'll make sure that I leave the car on some very nice Limestone bricks. Similar to Bath Town Centre.
cheers

is this a standard elise S2, or any of the specials ?The Elise has shims on the upright to adjust camber (front and rear) and washers on the top wishbone front mounting to adjust castor. Toe is easy to set using the track rod ends (front) and toe-link (rear). Would be surprised if the VX is assembled any differently!
Anyone with the tech manual able to comment?
cheers

Took my car to my race car specialist.
Err...there are no geometry settings that can be adjusted on the front.
your "race car specialist" must've had indulged in heavy ,
since there are a pack of 5 shims front and rear to adjust the camber.....
I did it myself at the rear, adding a thicker shim to decrease the excessive "/ \ " inner wear, and I will do the opposite at the front today, to decrease the outer wear, a bit too pronounced for my liking, seen after 2 trackdays. with the Exige setup +spax combo.

I gave him a ring and he said that he hasn't looked at the rear (because the most important adjustment to make is on the front), although he said that the rear is likely to be able to be adjusted. However adjusting the rear on its own will not provide the correct result. At the front you can adjust the castor only (with the shims you stated).Took my car to my race car specialist.

Have you ever adjusted the negative camber on the front ? , because if this is the case, then my specialist must have had a few too many.

...as a matter of fact, I just finished adjusting the FRONT camber...it took me ...what....25 mins maybe, for BOTH fronts....
removed ONE of the FOUR front shims, so to increase the "/ \" (vertical inclination, so to speak) angle.....
first impressions is an increased steering response, diminished understeer and crisper turn-in....I also went for a quick 180-190 kmh blast, and speedy stayed remarkably stable (very important...lerned it from last year's Ring experience... ).
I guess once I reinstall the 195-16 yokos, the effect will be even more dramatic...
I MIGHT try a bit more open toe, to take the aggressive turn-in edge out...
I'd suggest this mod mostly for the lowered cars, since on normal setups it MIGHT increase the inner wear a bit much, but not sure about that....visually it IS noticeable....
worth a try anyway, it's a breeze to put back togheter in case doesn't work...
it's definitely the cheapest (zero cost indeed!) "understeer-reducing-mod " on the market!
will post piccies....

if that's the case.....a) The VX has got adjustable camber settings, and the VXT doesn't.
congrats Vauxhall for screwing up enthusiast's modding needs, and more proof that the VXT was thought as a fast cruiser more than a dedicated track tool.
...still....can't fathom how an extreme sport car can be w/out a camber setting...

I shall be doing some more investigating.if that's the case.....a) The VX has got adjustable camber settings, and the VXT doesn't.
