Almost sold my Tuscan due to poor handling! Fixed for £20!
Discussion
I see what you did there!! I'm looking at a few quid improvement and then suddenly I'm contemplating a full wheel change!!
The trouble is, I'm not good at saying NO!
So, front-end re-spray and new set of wheels.....
Cheers (I think!)

Sorry to butt in, but does this apply to those of us with Cerberas? I only ask as we have the Tuscan wheels too!
Cheers
Rob
It sort of does, but Cerberas don't have as much clearance around the arches so that when you fit the spacers the wheels start sticking out of the arches. The problem with Cerberas also is that the 225/35 tyre is really a bit too narrow for th 8.5x18 front wheel so the tyre is too stretched and consequently doesn't operate as it should. It won't come as any surprise to you I'm sure that the SP12 wheels deal with both of these issues simultatneously... as well as being 3kg lighter and much stronger Cheers

A Mk.3 is a Mk.2 with the convertable dash. Apparantly they have revised electrics, although to call it a Mk.3 is a bit rich.
Mk. 2.1 is more appropriate I think.
Dave, what is mine then its a FULL CONVERT with the swoopy dash, so is it a MK2 A MK2 1/2 or aMk. 2.1 is more appropriate I think.
MK 2 3/4 or a MK3....

Will this reduce/eliminate what many perhaps incorrectly perceive to be bump steer? I know that the Sagaris has revised steering arms that bring the track-rod into a more horizontal position, I presume with a view to reducing bump steer. The Sagaris though uses the same wheels/brakes/hubs as the Tuscan so in theory it should suffer from the same offset issues?
The Sagaris has a much wider track anyway and a different rack and PAS arrangement so it's not the same set-up. Crucially, the Sagaris was engineered with 18" Spiders.Night Rider said:

DELIVERY UPDATE:
The spacers were late arriving and only arrived late this morning. Despite my best efforts trying to juggle the packing of spacers, preparing for ROAR and fixing a few cars in between, I didn't quite make it arriving at the post office at 17h32. So, sorry but they won't be shipped until Monday (delivery Tuesday). As I'm sure you can all imagine, I'm more than a little disappointed because I am looking forward to you all trying these out as much as you are.
Sorry for the delay.

I fitted the spacers to the car today. Took it out for a drive and there appears to be an improvement in the handling, can’t quite put my finger on the exact change but it feels better. 245x40x18 F1's on the front with a good wheel alignment. Still follows the furrows in the road to an extent. But for the cost and min time to fit you can't go wrong.
Just fitted some cheapo 3mm spacers to my Mk1 Tuscan as I was quite intrigued by this one and a little bit sceptical. Sceptical because its supposed to work for all tyre sizes and the intersecting point of king pin inclination and centre of contact patch most definitely changes if the rolling radius changes, as it does with different tyre widths and aspect ratios's (I have 225/35ZR18's).
The result? Well, round the twisties its much improved and inspires more confidence, it's almost even chuckable. But, and so far it's a big but, high speed wander and tram-lining is worse, as though the front toe settings are parallel or even toeing out (it may be worth looking at rear toe as well).
My initial thoughts are that it's a step in the right direction and combined with a change in Geo elsewhere we could nail it (or front splitter?).
On a different but related subject I'm convinced the Tuscan has a degree of bump steer that is unacceptable although I haven't had the time to measure it. I spent many hours designing and fabricating a single seater and its suspension systems only to experience bump steer of epic proportions. I then learnt the geometry behind bump steer and it's eventual cure, with the help of the late Alan Staniforth (I highly recommend his Race & Rally Care Source book). This experience has made me a bit paranoid about BS and one big regret I have is I actually threw away the BS gauge I made all those years ago.
Anyway, be interested to hear how you Guys get on with the spacers, no doubt there will be differing views.
May see you at Goodwood in the morning (TUSC FUN)

My hopes of fitting the spacers this weekend and trying them out have fallen flat on their face, my Tuscan has a problem and is back with Str8 Six. Doesnt look like i will be at Goodwood in it either, Gutted 
Its the first and prob the last time i will be able to spend the whole weekend at goodwood for a few years....i bought the tickets ages ago
So...if anyone sees a guy in a black VW passat at Goodwood that sees you in a TVR and frowns like a baby with a smacked ass, wave and say hi, its me.

Bump steer on early Tuscans is pretty bad. The track rods post 2001 were shortened (the rack was widened) to line up with the lower arm pivot lengths but, due to the outer rod end being too high, the angles are wrong, creating bump steer. This seems to have only been corrected with the Sagaris which has offset steering arms, lowering the outer rod end. It can be corrected by using rose joints to connect the track rod below the steering arm. The result? Well, round the twisties its much improved and inspires more confidence, it's almost even chuckable. But, and so far it's a big but, high speed wander and tram-lining is worse, as though the front toe settings are parallel or even toeing out (it may be worth looking at rear toe as well).
