1.6 vs 1.8 Avensis parts

[Darren Carthy]

Hi all, 

I'm looking to up the spring rate of my 2006 1.6 VVTi Avensis, i've been told by a veteran that the 1.8 model came with a harder set of struts, after examining the part numbers however, I cannot find any difference between them, 

Can anyone advise on a harder toyota manufactured suspension to suit the avensis? I don't want to go after market unless absolutely necessary

Kind regards, 

Darren

There should be no difference in spring rate according to the following links -

The weight difference between the 1.6 and 1.8 should hardly be much. The stroke difference is 10mm, which only the block, crankshaft and connecting rods will be different (add the longer cam chain). 

If you were using springs from a diesel engine, then it be firmer!

HI Konrad, 

 

Thanks for the link, on paper the diesel and petrol suspension parts are identical, I was hoping there would be some difference so I cold justify purchasing the springs/shocks from a larger engined model but unfortunately its not the case, 

I've found a set of 25mm lowering springs from Eibach that offer a progressive spring rate and are suitable for standard shocks, I think i'll give these a shot, 

 

Thanks for the reply, 

 

Kind regards,
