Coilovers

A curious question please guys. I am looking for some coilovers and reading some results from peoples findings as to particular brands one aspect really stands out.

 

The 350z was designed on the rear with separate shock and spring arrangement (not sure if there is a technical term), which does seem quite common. I am guessing Nissan know there stuff :teeth: and there was a reason for this? However, some aftermarket coilover manufacturers offer a combined spring and shock as per front, so looking for some insight as to why nissan choose their set up and some manufacturers choose not to follow??

 

I am not condemning any coilovers here by the way, just want to understand before i commit to making a purchase.

Pretty much all coilovers will be available in both separate rear springs or full coilovers. The most common choice are the separate ones due to needing to reinforce the rear strut if you choose to go the full coilover direction.

 

I know plenty of specialists say it needs reinforced, but there are several owners on here and many in the states that run full coilovers and I've yet to see it cause any damage or have negative affect. Best bet is to be safe rather than sorry and buy the slightly less expensive but just as good seperate rear spring style.

The question is more so what would be the differences between the two and why Nissan went with seperate , not availability. Sorry if that wasnt clear.

The inboard springs design are very common in the European circle, almost all BMW use it.

There are advantage and disadvantage... but one of the main advantage is cost.

The inboard springs design are cheaper to produce, also require less accuracy on the springs.

 

For a performance point of view, both suspension design work... but most prefer a true coilover design as it feel more accurate.

It is also easier to tune the suspension with true coilovers as it will have a much closer relationship between the actual springs rate and the wheel frequency.

 

That is why most "race" suspension system you see for BMW will have a true rear coilover design.

I hope that helps. :)
