Several considerations here.
If you add a splined adaptor to the hub so you can stick splined wire wheels on, you are adding to the unsprung weight which can result in a deteriorating in handling.
If you use the readily available bolt on wires, the wheel centre can be even heavier.
Then there are strength issues. The AC Cobras used wire wheels on the early cars, but switched to knock off Halibrand alloys for the 427 engined cars. My Lamborghini came with knock off Campagnolo magnesium wheels (a very expensive option to put on a Solstice) but Borrani wires were also used. The Aston early DB series used 72 spoke wires. With a lot of power, the wire wheels can be marginal.
On my rebodied MGA, I stuck with wires as I think it gives the car less of a kit car look. They are AC Cobra mounted on Triumph detachable splines, but then I am dealing with only a bit more power than an NA Solstice and with almost 1,000 lbs. less weight.
OTOH, the West coast Jensen dealers offered an option on the Jensen Interceptor of wire wheels made by Zenith in California. The mated with a serrated rather than splined adaptor and seemed to work just fine with a 4,000 lb car with a big block Chrysler, so might also be reasonably durable on a Solstice, though still not advisable for drag racer types, nor solo event participants. They were 7x15"
And in any case not a cheap way to go.
