If you've seen the video of my clio (on facebook group) doing an autosolo, it's quite strenuous on the car; hard launches, steering quickly and bouncing off the limiter.
Will the wedge take that sort of abuse? I've never hit the limiter on the tvr and try to be as nice to it as possible. Not sure how it'll hold up drifting round a set of cones on the limiter!
Yes I have a severe disdain for tyres!

There is no built in limiter as such, these engine stop reving once they hit valve float and the lifters pump up. 
On stock single valve springs this is somewhere in the 5-6k rpm region, and probably isn't too bad on the engine as all the stock components are good for 6k (providing you haven't got a long duration cam, and lots of preload on the lifters which could risk valve to piston contact).
On dual valve springs valve float is much later, 6700rpm on mine and at those sort of revs your beyond what the stock valve gear (rocker arms and shafts) are good for.
In either case i reckon and aftermarket rev limiter would be a wise purchase.
What would the number be for triple valve springs???On stock single valve springs this is somewhere in the 5-6k rpm region, and probably isn't too bad on the engine as all the stock components are good for 6k (providing you haven't got a long duration cam, and lots of preload on the lifters which could risk valve to piston contact).

This was me on track (well mostly) at Blyton Park in lincs last year.

Looked like fun ^ to be fair to your spin...track looked damp in places? 
It was very greasy. I had the other lad giving me tuition because I had already spun it 3 times.
We worked out it was because of the weight transfer, the weight was still over the front wheels and it just snapped round. He said to me after that there just wasnt any warning it was about to go, it just went! He described it as "a bit of a beast"
I have been round there in the dry and it gripped really well but in the wet/greasy conditions get all your braking done well before the corner to give it chance to settle before you turn in.
Sorry to chime in from a Chim perspective... I did 5-6 auto solos in mine.
Only issue I had was the power steering, I blew the pinion seal on a tank slapper going lock to lock a few times and oiled down the course much to everyone elses frustration.
The rest held up ok. I would really recommend it to be honest, much better to be comfortable going sideways given how easy that is to achieve.
