How to make a Tuscan quicker round corners
Discussion
What recommendation would you make for improving the cornering of a Tuscan. Its a standard road car - not rose spec or anything and runs on 1A tyres. I use it on road but also for TVR Speed Championship. It is the latter I want to speed up. I have been considering best route to improving for some time and would welcome suggestions for suspension. I still want it road usable and don't want driveability on road to get much worse
I have had corner weighting and wheel geometry checked in past and will do so again.
I have already taken steps in terms of driver improvement, next is car
Suggestions?

Would get somebody that definitely knows what they're doing to set it up - had a couple of "supposed" experts do my Tivs and fail. Would agree that making sure the camber, etc. is correct too is a must. (And decide how much toe-in/out you want) Would also get some wheels and tyres suited to the type of racing being done - probably ditch the 18" wheels for 16s or 17s. Would switch the suspension to adjustable Ohlins/Nitrons so you can tweak them for race days (and have them be FAR better in general, too). And I'd upgrade the brakes if you're planning on pushing it for extended periods, too.
If it's a Tusc I, then there may be some (expensive) options around switching to the Tusc II steering rack, mount points, etc. The T350 definitely feels a LOT better for that.

This is all V good advise.
Nitrons are the best money that i have spent on my Tuscan, combined with a 'proper' set up it has transformed the handling.
Has anyone changed to the rack and mount points from the mkII ?
If so who did the work ?
Got nitrons on my mkI S and made a huge difference, but I did like
the handling of the mkIIS I drove, thought the steering especially
on bumpy roads was great, although did feel a bit more distant.

The basic problem is that the rack is mounted too low,leaving the rack and the wishbones out of line,which is less than ideal on any car,promoting bumpsteer.
I really dont know how the fundamentals of steering geometry can be overlooked by the designers, but this is one of many things with these cars that, with a little bit more thinking could have been a lot better.
You can actually move the Tuscan 1 rack upwards using a couple of blocks,and a bit of courage and oxy/acetylene to "tweek" the chassis rail where the column comes out of the bulkhead and passes under it.this causes the wheels to toe out but just re set the tracking.
I Raised mine enough so that the cut-outs in the chassis are almost redundant.
It really makes a difference because it brings the rack ends parallel with the wishbones,it cures bumpsteer on all but the worst roads.
Cost sod all but a couple of hours work,
dont know if its as good as the tuscan 2 conversion but it`s certainly cheaper.

How tough is the speed challenge on the wear and tear of the car? I'm thinking if doing a few rounds but don't want to wreck my car?
A decent diff would probably help too, especially through & out of the corners. I dont know how effective the diffs are as stock but generally an upgrade to a more aggressive will transform most cars. You'll get better balance on the throttle, much more control & both wheels will be driving the car forward as opposed to one or one & half. Have you any pictures of the car exiting corners? what sort of tyre marks does it leave? this is always a good indicator. Does it do one wheelers out of tight corners? if so you be gaining seconds up those hillclimbs by upgrading.
Also the Monaro boys found that adding Redline friction modifier tranformed the diff action on their UK cars, I've driven several of them & compared them, the difference was astonishing, I have no idea how it works but it does plain & simple (plated diffs that is)
I would be interested to know peoples opinions.

its not bad. You're only doing runs that are 1 or 2 miles long at a time so its not like you're putting it under pressure for long periods. On the other hand it is fantastic fun. The adrenalin rush of the competition is fantastic, and since you are 30s apart on the track you can commit knowing that there is no idiot the other side of the corner to spoil your day - the only idiot that can do that is you!.
Track days are extremely tame in comparison as far as I am concerned. All the sprinters are very welcoming whether you are good, or not so good (like me). Why not come along to met everyone and watch an event? Roughly where are you and I'll let you know when and where an event is close

My good mate Jes does the sprint championship and says the wear and tear is far less than a track day. Runs are short so engine and brakes dont tend to get overheated.

And your good mate Jes pushes the cars more to the limit (and occasionally beyond) than almost anyone else: superb driver; superb bloke; total nutter on the track. He's right tho, wear and tear is much less
As for Tuska or anyone else - see
www.tvrspeedchampionship.co.uk/
That has the full calendar, FAQs etc

The list of work Jes has had done on his cerb this winter would make most TVR owners weep. However, its still not ready and i think he has already missed an event or two.
Be afraid, be very afraid......

I am not afraid of Jes for one simple reaslon - if he completes the runs I have no expectation of beating him. He intends to win the championship back and may well do so, my ambition for the year is to be top 10 (especially in a completely unmodified car as the suspension changes will be for next year).
