Anyone had the bump steer mod on their tuscan
Discussion
There are a couple of different options
Raise the rack with spacers
Change to sag type steering arms
Str8six full mod.
No definitive answers as far as I am aware, ie. track times/ owner feel as if you do one you don't do the others, then walford is also trying all sorts of things with geo.
What wishbones/rack have you got?
Anything has to be good though,I've had a few trouser staining moments when full on!

Str8six full mod is what exactly, and any idea of cost?

About half way down, basically all of the above parts. There are 2 different wishbones, two different racks, steering arms and geometry changes. Bit of a mine field.
Add in suspension and tyre choices, bushes, spacers and general condition, there are a lot of factors.
I haven't gone the probably preferred (Str8 six style) route of saggy steering arms but have achieved the same end result by flipping the track rods to mount below the arm and spacing rack height to fine tune. I also fitted a later wider rack at the same time.
The result on my '00 Tuscan was a big improvement. I already had Nitrons fitted and was running the preferred 235/40 tyre size but the car could still be scary under heavy braking or when hitting bumps mid corner. Toe in on bump is not the best for high speed cornering stability! The changes on mine have resulted in slight toe out on bump which calms the car down massively on uneven surfaces. Country roads are no longer the roller coaster ride they were.
I'll may end up buying a pair of saggy arms and re-doing mine at some point.
I know Walford has made his own cranked arms to suit the Mk1 geometery. I wonder if he would be interested in producing a few sets??

Speak to Russ at RaceProved as they do a kit
Is the kit any different to str8 six?i.e. sag steering arms and a rack spacer? You would have to get the geo re-done afterwards?
Str8 six mod is quite expensive @£395 + vat when you can get the arms for £120 each and the spacer isnt much more than a piece of 8mm odd alloy strip with some holes in it. I guess you pay to have the geo re-done in that price - about two hours worth by the look of things!!

To be fair it's not just a 2 minute job to swap the steering arms.
Fully agree and i understand there is a big labour element to this - but i would be happy to tackle myself if i didnt have to readjust the suspension afterwards - dont have the equipment (or skills!) to do the set-up...

I'm with you and enjoy the tinkering element, which is why I went the DIY route. You could get the tracking close enough to be able to drive it somewhere for the final setup.Have had several set ups on front end with respect of camber (now .75 deg static) castor (now 5 deg) steering arm geo
I thought the car was handling quiet well , but got Paul at PPC in Melton to test drive it (he,s driven hundreds) and he said it does handle as well as some of the later cars he looks after, (they have nitrons on I dont)
think i will set KPI to same as the later cars

Do you think you have any improvement on the standard saggy arms? Seems like progress to have a car handling as well as a nitron car!I thought the car was handling quiet well , but got Paul at PPC in Melton to test drive it (he,s driven hundreds) and he said it does handle as well as some of the later cars he looks after, (they have nitrons on I dont)

Interested in doing a few sets of steering arms or is it not worth it ?(i.e. we may as well buy the sagaris arms?)

I looked at it, there isn't much in it if you ask me. If they fail and you lose the steering might be an issue for the insurance. I wondered about doing a group buy?Interested in doing a few sets of steering arms or is it not worth it ?(i.e. we may as well buy the sagaris arms?)
ive only had my tuscan for a month and a half, purchased from racing green. Speaking with them the main difference between the sag and tuscan s is that they have a wider chassis at the front and therefor a wider track. Racing green put spacers on all the tuscans to widen the track to that of the Sag and S model to reduce the twitchyness, but i cant compare as the only tuscan ive driven is the one i own which has the spacers.
however, going on racing greens word, it makes a considerable difference!

Sag uses different hight and width pick up point for wishbones on chassis this brings all sorts of dynamic changes, as well as the static track increasehowever, going on racing greens word, it makes a considerable difference!
