			From what I've always heard, TVRs are horribly dangerous, over-powered, tailhappy deathmachines. 
 
 
So, understeer issues or not, I would think that the tail would not only be quite easy to kick out, but also easy to lose control of... 
 
		 
Good description of most TVRs, the real things are legendary for the level of commitment and skill needed to drive them on the limit. 
To put this to the test I ran a 350c and Tamora around the Grand Valley Speedway, I'm using the same corners for lateral g calculations from the 
BMW Tyre Analysis post.
TVR 350c
The 350c is a bit of a nightmare around GV, as its stock gearing just does not suit the circuit. You always seem to either ride the rev limiter for a short distance before the corner or change up just before braking; not a happy choice.
One thing that is abundantly clear is just how damn fast the 350 is in a straight line, and how much of a handful it is in the corners. Get the power on too quickly as you come out of a corner and you get a slight wiff of understeer, that then rapidly turns to oversteer. To maximse corner exit speeds you need to keep the tail in check, and that means feeding the power in gently.
Don't get me wrong, it corners damn fast, but it limits your corner exit speed.
Grand Valley  - 2.21:098
1st Hairpin - 56.8mph / 1.11g
2nd hairpin - 42.8mph / 1.11g
Sweeper - 75.8mph / 1.07g
The Autocar test I mentioned in a previous post recorded a peak lateral g of 1.14, the results above were achieved on N2 tyres and are damn close. The lap-time above does not reprent what the car is capable of, but its gearing just does not suit this track.
Tamora
The Tamora has a similar feel to the 350c, it just seems to have been softened slightly (remember this is TVRs user-friendly model), more understeer develops when you push hard out of a corner, still not a lot, but anything is more than you get with the 350c. It still progresses to oversteer, but in a more measured manner, which makes it easier to modulate and catch. 
The Tamoras stock gear ratios are also a much, much better fit to GV, giving you one less thing to think about. 
Grand Valley - 2.20:195
1st Hairpin - 56mph / 1.08g
2nd Hairpin - 39.2mph / 0.97g
Sweeper - 74.8mph / 1.04g
The overall lap time is a second quicker than the 350c, but the gearbox kills the 350c here. Another track and I think the story would be very different. 
Even with this in mind the Tamora is a much easier car to drive quickly, the 350 by contrast is clearly capable of much more, but much more care is needed on the limit.
Exit a corner to quickly in the Tamora and it will understeer enough for you to read and react to. The 350c just uses the understeer as a sign that its about to try and throw the back out, and by the time you've read the message, your going sideways. 
Well thats my contribution to the TVR bit.
