My car wanders at high speed - is it normal?
Discussion
Has anyone else had probs over say 110+ whereby the car is all over the road and feels like its going to break loose any moment?
Ive always put it down to the 18" wheels but I now think it must be something else.
Apparently the 'S' is totally different in terms of suspension mountings etc. Is this because all us Red Rose option people found high speed driving more than a bit freaky.
I'd be interested in other drivers opinions.

Righty oh!
So I am not the only to find our beloved TVR a bit hairy a 110+mph. Yesterday I let loose on a nice stretch of motorway with no-one around, climed to 140 on the counter (surely must be wrong
). I was so freaked that I took my foot off the right pedal after a few second. Blimey, felt like the slightest bump could have sent me flying around the moon. I am really impressed when people say they push their Chimaera above 150mph. May be they have upgraded the suspensions, or may be it is just my car... 
My new Tuscan (8 weeks old) appears to have similar high speed instability.
See my previous post "Self steering Tuscan."
If there is any camber or ruts in the road they seem to dart up and / or down them with worrying alacrity.
I nearly Sh£t myself the other day.
And yes the Cerbera, Chimaera and Griffith were not like this.

Our Cerbera is rock solid at 160.....
(I presume the Chims & Griffs are the same ?)
Well, as I said mine isn't. In fact it is far from it. As far as I know, Chimaeras or Griffiths have never been reputed for the quality of their handling. It'll be interesting to hear other people voicing their opinion.

R...Guys,
Have you had your wheel alignment checked.
The latest Mole Valley demonstrator has had a 4-wheel alignment done with specs supplied by the factory and felt a lot more stable the second time I drove it.
Apparently the cars' alignment can be way off these specs when they're delivered.
Just something to check...

TuscanRR,
I've done 145-150mph in my Tuscan a couple of times on the way to/from Le Mans this year (showing a couple of boxsters and an Impreza the error of their ways
) and the car felt fine (ever taking corners at 120 on a two lane road).
I've just had a number of upgrades and a service carried out at the factory - including checking the geometry - and the car handles even better now. The steering feels more direct (less vague) and it doesn't tram line as much.
I'd suggest you get a PROPER suspension geometry setup on your car (don't assume it was setup spot on before delivery 'cos they're not always right - or even close). Who ever does the setup for you, get them to get the spec. for 'parallel alignment' from the factory service department. This is what I've had done and it does seem to improve things. Aparently the parallel alignment has been developed for the Tuscan S (with the new suspension pickup points) but still seems to improve a standard Tuscan 4.0 on 18" wheels.
Give it a go and let us know how you get on.
Mike.

Thanks Mike,
Who can do check the geometry, is it something fernhurst could do for me? or is it worth going to a specialist?
Many thanks for the info.
RR
I don't know about Fernhursts but I do know that the usual tyre places can't/shouldn't do it.
I seem to remember someone on the Tuscan egroup talking about Micheldever(sp) Tyres being able to set it up properly - you could try them (or search the egroup archive first)

My Chimaera was fine, 153 on the autobahn felt rocksolid, took some corners at 130-140 still felt fine, the following bike actualy backed off.
My Tuscan feels great I've had 150ish afew times and no problems including a 145 with sharp braking with no rear end instability (but I'd definately got the weight transfer). I've also had corners at 140ish no problem.
I have noticed though that the breaks are quite rear biased. It would not be hard to lock the rears if you transfer weight to the front quickly and snatch at the brakes. (my brother did it!) Rules of the game is smoothness, especially at speed.

The only real fix is a TuscanS. Its absolutely the business.
The best I came up with was to fill the tank before pushing it. It does really help.
I've had a std 4.0 18" wheels, I suspect that the RR might be better as it might not dip at the front so much when trying to slow down.
The back spoiler is the one you want but they won't do it without the lower
lights, cheaper to ell and get an S. The front I think is more to keep the front down as weight increases on the back.
Get an S it fixes all the stability problems.

Ive had my Chim 4.0 up to 155 on the autobahn. MY Chim 450 to almost 160 they were well planted on the auto bahn unless in 1 case I had really bad cross winds. My current car a Tuscan feels a little less firm at high speeds. But this time of year isnt best for getting to 140 plus speeds
My standard Tuscan with 16" wheels feels just as planted as my Chimaera. Had the Chimaera upto 155 and was fine. Tuscan has been to 150 quite a few times and feels fine. One occasion in damp conditions rouns a slight bend at 145ish I hit a bump on the road, I had considerable suspension movement but no problems, the car coped very well. (If it hadn't I can't see me recovering it at that speed!)
All I would suggest if you are not happy with the feel is a full geometry check and if it is an older car it could be bush wear.
