Sirion GTVI Suspension

Forum: 

Hi All
I have a Daihatsu Sirion GTVI 2000
I want to upgrade the shocks,springs,Rims & Tyres

Overall I am happy with the car but it doesn't handle well at all.
I am looking at lowering it by 40MM
I have had a look for Eibach springs as they are the best you can get but can't find any.
There is a brand called Ventura that sells on Ebay, I am not sure what they are like.
I also want to put 16's with low profile tyres but not sure what is the limit Unknw
Has anyone found a sway bar that fits Unknw
I had a look under the car and can see a front sway bar but the back looks like a solid axle.
Any suggestions guys Unknw
