There is gap between the cross-rails, similar to the picture below of a Palio Stile S10

I was advised to fit a brace between the two rails to help stiffen the suspension at the bottom.

I was advised that this will help with pull away and braking, the cross brace reducing the flexing and this will also help with tyre wear.

I also really appreciate your advise on the 15x6,5j 4x98PCD 35 offset rims. I am going to source a set I like and will post in due course.

I just want to make 100% sure the suspension is up to scratch before I fit them.

Also, I will have to manufacture a cross-rail bracket. Here are pictures of the suspension from the bottom.

I am thinking of putting up a brace between the two cross-rails and the area just adjacent where the firewall meets the lower chassis. See photo below of before and after...



Any advise or suggestions would be appreciated.

Re: Fiat Siena/Palio OEM rims

Here is another option... I think with the bars pulling on opposite ends and with the plate in the middle, it will reduce chassis flexing a bit... or too much.

Any thoughts will be welcome....

Re: Fiat Siena/Palio OEM rims

Start easy: find some decent rims: 15"X6,5J, 4X98, offset 35, and fit quality tires 195-50R15H, with the correct pressure, and see if roadholding improves.
( I like a rim with 5 spoke design....)
Take care with the bolts, use ONLY bolts that come with the alloy rims, and thighten them according to specs.

Let's start with that...

Re: Fiat Siena/Palio OEM rims

So,

I am taking Peter's advice and will get a set of 15" 6,5J rims, with a Michellen 195/55R15 tyre. I am struggling though to find 15" 4x100PCD 6,5J rims in this country. When you ask for those spec rims, they always say: "O, you're looking UNO wheels"... well I guess I am.

So I will have to consider the alternative and go for 100PCD's and fit a 98PCD to 100PCD adapter, similar to the one shown in the picture.

I have read similar threads with regards to these conversions and there are some against, a lot for and then there are purist... the thing is, in my country, I do not have a lot of options and will have to go this route.

Additional advise on this subject with be appreciated. I am also not sure about the additional spacing it will bring about. I am thinking that the extra space might cause additional felxing too.

I am also still worried about the front weight and the flexing on the chassis rail. I have searched high-and-low and have come accross FIAT Uno threads where the owner have installed a (custom) brace, compensating for the gearbox mounting and then taking additional braced to the front of the car. Yes, it will influence the clearance, but it is a sacrifice I am willing to make.

I will definitely be putting in aftermarket poly-bushes and this will also hopefully help. I have also attached a picture of the brace I intend making for the car.

I have also attached pictures of a lower control arm kit (custom made) which I found on another forum. I suspect they are more rigid and will compensate a lot for those rolls. That is just a thought at this stage.

I really want to get this suspension "bullet proof"... I am not looking at
tuning my ride to become a racing car... just a reliable strong-handling suspension.

Thoughts and advise will be appreciated.

Regards
Hugo

Re: Fiat Siena/Palio OEM rims

15 inch 7J rims are OK too, and it is 4X98, NOT 4X100....
And you need 195-50R15 H (or V) tires.
I personally would NOT fit those adapters, I'd go for the correct rims..

Re: Fiat Siena/Palio OEM rims

If you don't mind me asking, why do you prefer the rim-option? Do you think it will improve the camber/overall ride?

Re: Fiat Siena/Palio OEM rims

15 inch goes well with the shape and size of the car, and 15" tires are less expensive than 16-17"ones.
The ( relative) smaller sidewall of the 195-50-R15 tires will improve handling ( a bit...).
