Almost sold my Tuscan due to poor handling! Fixed for £20!

[Curdster]

Just had the spcers fitted to the car. This was post fitting Nitrons and having the geo done. So the verdict after 300 miles this weekend is that it does feel less twitchy although still trams sometimes. It's better but not amazing. But for £20 probably worth it.

From the photo on your profile it would seem that you have 225/35 front tyres, is that the case? That is far and away the worst set up for the car (much better with 235/40 or even 225/40 both of which improve the car's handling a great deal, then the spacers make an even bigger improvement). Hope that helps.

I agree with the above, I had S03's with 235/35 on the front, used to be a real handful on B roads and my old mans griff would leave me standing cross country. Changed them to Toyos on 235/40 and although it looks odd to have a higher side wall compaired to the rear it handles so much better. No bump steer and very little tram line, going to make up a set of spacers to see if it improves it further.

You could always buy a set and reward the poeple who actually came up with this solution

I thought the plates are only 3mm or is this an optical illusion.

Are the bolts bent too?

for the avoidance of doubt you only get the spacers...

they are 3mm

TBH Not worth the effort trying to make your own, these are good and there in a day IMHO. I am an engineer with a shop and it wasn't worth it so I bought them from Matt.

Devil you are right about the fronts. So if I change them, what is the best, the 235/40 or 225/40?

235s seem to be the most preferred but given that most (with 225/35) have 255/35 on the rear, opting for the 225/40 might be a better choice so as not to upset the rake of the car (unless you have adjustables in which case you can adjust ride heights anyway). Best set-up seems to be 235/40 front and 245/40 rear.

225 40 work really well on the front my Mk1, i think they are the closest in diameter to the 255 35 rears. Transformed handling, tramlining and bump steer and the spacers made a good difference too.

[ukcerb]

Thanks fitted today and had a drive when the roads had dried up. Definate improvement at all legal limits!

[brownpb]

Ive been away for a while so havent driven my car I understand unfortunately Silverstone have closed, where can I get these speacers from now? Is Matt still producing / selling independently?

[nrick]

Matt is still selling them on ebay

Bump steer is coursed by track rod not swinging the same arc as the suspension

this can only be corrected by moving the rack up or down, altering the length of the rack

or moving the track rod end up/down, in/out on the upright


putting on a tyre with a bigger more flexible sidewall may help hide the problem, as would adding rubber anywhere on the suspension

[dvs_dave]

+1, although this mod corrects a dodgy scrub radius which can be mistaken for bump steer due it causing the steering wheel to writhe a little in your hands when goivng over bumps.

[Pacman1972]

Might seem a daft question but doesnt the spacer put a lot more strain on the wheel bolts?

Looking a the pics on ebay it looks as if the centre lip is absorbed by the spacers leaving the bolts to take all the weight.

[Basil Brush]

I think that pic is a bit misleading, probably due to the disc having moved. On mine there is still enough of the hub to locate the wheel.
