Steering Geo early cars

[Walford]

Have just set rack height and flipped track rod ends over,
was at least 35mm out car is completely trans formed, not sure how these cars have been around for ten years, with steering Geo so far out

[PetrolHeadPete]

Can you share a bit more detail. Did you use the revised steering pickups or did you really just bolt the track rod end in upside down ?

Photos please

[blueg33]

Please can you share full details? Incl geo settings after and tyres sizes, spacers or no spacers etc

Cheers

Same here, could do with some photos..

Thanks

,
Tyres are less than average, so are the stock dampers, springs are Eibach 14/03 D 0368 3mm wheel spacer fitted

just getting rid of all the bump steer transformed the car beyond believe

you can have the best dampers and tyres in the world, but as you enter a corner one front wheel becomes loaded the damper compresses, if at this point the steering is turned by the and track control arm and wishbones swing different rads the driver has to correct this to were he want the car pointing, this is compounded by the fact he lifts the throttle and the damper comes back up, moving the steering again
I think the tyres and damper part of the handling problems something that should be looked at after this problem is sorted not before

you just need a combination of rack height and track rod angle that swings the same arc as the upright, its that simple

with the damper and spring removed, its easy to find the best rack/track rod end position

But you've not just raised the rack and flipped the track rod over, you've also fitted the Sagaris steering arms. These are designed to have the track rod in that orientation. What you've done is essentially the Str8six bump steer mod.

If your car had those steering arms already fitted (would be very odd if that were the case) and the track rod was mounted on top of it, it's hardly a surprise that you had horrendous bump steer!

I thought the same... definitely look like Sag steering arms.

sorry thought was passing on helpful info

if you just flipped the track rod ends over the tapper would be wrong, obviously, the track arm is not std

Where did you source the arms from?

I'm asking about the steering arms, not the track rod arms.

Sagaris Steering Arm (as fitted to your car)


Standard steering arm as normally fitted to the Tuscan


Your car has the Sagaris style steering steering arms fitted, however these are not standard fit so was wondering how they got on your car as you didn't mention anything about changing them.

FYI, the str8six bump steer mod consists of raising the rack, fitting the Sagaris steering arms and flipping the track rod over as you've done.

My car has steering arms that were made for suit the Geo of a MK1 year 2001 Tuscan speed six not a Saggy
my car has never been to Str8six, i don't even no were it is, was posting info for people who want to sort there own cars out, not take to dealer



My two point are
1 moving the rack will not get rid of the bump steer without also moving the track rod end
2 the amount of bump steer on the early cars means what ever dampers, springs and tyres you put on the car it will not handle

end of comment,s on Tuscan Geo, seems there are people out there that no a lot more than me
thanks for telling me what i am running on my car

FYI



how this is achieved is irrelevant

I realised they weren't saggy arms from the finish on the cranked section, hence my question about where you sourced them from. Could you let me know?

[Robertjp]

V confused by this thread....

Could it be true that some of us have different steering arms?!

[Basil Brush]

As standard, all cars except Saggys had the flat arms. The cranked ones were then made for the saggy to correct the track rod inclination.

Easy Tiger! We're just asking questions, not doubting you in any way?

It's reasonably well known that the Tuscan has this geo problem and that this is a way to improve it, however the only place I'm (we're) aware of that offers these modified arms is Str8six (a TVR specialist near Oxford).

Consequently we're interested to know where you got those modified "Sagaris style" steering arms from as that's the crux of the modification. Some more info on this would be helpful.

[Basil Brush]

Not sure what Str8six sell the parts for but Racing Green list the standard saggy arms for about £115 each incl vat. If you do the work yourself you could replicate the Str8six mod for about 250 quid all in.

[Robertjp]

whats the 'drop' / height difference in the saggy arms - 35mm as Walford suggests above??

May be able to get some made

This whole topic is very interesting to me as I'm stripping down to the bones my W reg Tuscan for a full restoration, and am very keen to know the latest thinking about what mods are needed to get early mk1 cars driving right.
Cheers,

So, it seems so far that the improvements are seen on Tuscans from late 2000 onwards.

The optimum set up is to retrofit saggy steering arms that allow the track rods to be dropped by around 35mm, a spacer under the steering rack of around 8mm is required to achieve this, but on some cars there isnt enough room...

All sounds fairly logical and straightforward

[Basil Brush]

You'd see improvements on all Tuscans, not just from late '00. The difference would be that it would be easier to correct it over a wider suspension movement on later cars due to the shorter track rods whereas, assuming a like-for-like static set up, earlier cars would tend to more toe out as bump increases.
