Sirion Front shockers

Forum: 

Right, this is likely to get a bit confusing, so I apologize to begin with.

I am in need of some new front shockers, the suspension all round is very tired and bouncy.
I am trying to keep the costs down, so I have been scoring the web to find some deals.
I have found some shockers made by optimal in germany. I have never heard of these before, but they seem like a reputable company. Has anyone had any experience of these shocks???

Secondly, I have also found some almost new original daihatsu shockers, however these are for a 1.0 and my sirion is a rally 2. After making some searches I found a few websites that stated the model number of the shocks indicate that they will fit on 1.0 and 1.3, they also cross ref the correct KYB part number for my car as an alternative.
I phoned my local daihatsu dealer who couldnt find the part number on the system.

So does anyone know if the 1.0 and 1.3 shocks are the same or is it not worth the risk.
