I've joined this site because my wife owns a '06 reg Sirion 1 litre, and I'll probably doing any further maintenance on it.

I quite like the Sirion, it's pretty much ideal for someone that wants a well specified economical runabout, and is not bothered by performance. All my wife needs is to be able to sit on the motorway at 60 mph, which the Sirion will easily do all day.

I quite like travelling in it - it's comfortable and has a nice airy spacious feel to it. The only issue I have with it is that even when cornering modestly, the body roll is quite alarming. As a passenger, I want to lean away from the roll like a racing motorcycle sidecar passenger - I swear that if I didn't the wing mirrors would scrape on the road!

They do lean a bit!

Recently I had occasion to test drive a sirion 1.5 SX and a fiat 500. Got to say the Sirion did lean a bit on the roundabout whilst the 500 took it in its stride.

Cornering roll

I also tried a Sirion 1.5 and thought it wasn't too bad in corners. However it's jimford's taste that matters here.

So Jim should try a Sirion 1.5 and if that rolls too much for him then BobF can tell him where to get stiffer springs wound for a fairly modest sum.

Thinking outside the box Jim could have a couple of special brackets made and parallel a pair of standard anti-roll bars, gaining more anti-roll and probably losing less comfort than using stiffer springs.

..............and all Jim wanted was a simple solution!

Anti-roll bar

I had the same problem with my YRV and fitted the anti-roll bar from the YRV Turbo, which sorted it. The twist-beam rear axle is common to the basic YRV and the Turbo version and thus the anti-roll bar bracket fixing holes are also common.

"What's that got to do with the Sirion?" do I hear you ask.
Well the Sirion and the YRV have many common parts and maybe the rear axle is one of them.

If that doesn't work out, I think the latest Sirions do have anti-roll bars and maybe they are backwards compatible with your wife's. The 1.5 Sirion may have a stiffer anti-roll bar yet.

None of this is for certain, but it gives you lines of enquiry.

New Sirions - All the same Chassis !!

2004 Sirion 1300 4 Track. And I love it.
Don't like the new shape much.

As far as I am aware the new box shape Sirions all have the same Chassis.
But I beleive the 1500S model which has the 1500 engine has stiffer Suspension.
It may be possible to fit the 1500 Springs to your wifes car.

I know you can fit the Rally 4 Springs to the 4 Track on the Sirion up to 2005 (Before the new bow shape)And they are much stiffer and cost £47 each.
I suggest you ring Daihatsu Technical on 0121 747 4000.
Ask for the technical section and ask if the 1500S Springs are stiffer and if they will fit your wifes model.

If they do - You have your answer.

Cheers, Bob F.

2003 Sirion Rally 4. And I love it.
Don't like the new shape Sirion much.Sorry.
