Springs

[Barney Paull-Edwards]

Can somebody point me in the direction of front spring rates for E34`s? Making my own coil-overs and need a starting point for new springs, assume TDS is about the same weight as 535?

I dunno what you're asking for but these are nice replacement springs for your model.

Thanks but tried them,not stiff enough,on fourth set and going coil-over as springs cost $26 so can experiment. Also ride height problems will be eliminated, hopefully.Need datum to start with.

I haven't found springs rated listed for the e34 before.

yes its its in japanese but
it does have the spring rates in N/mm for H&R springs including e34s

[BigKriss]

no it doesn't, please show me where. It only states the lowered drop that is common knowledge.

[pingu]

Eh? It's got the spring rates in N/mm.

[Barney Paull-Edwards]

Which column? And can anybody clever convert N/mm to Lbs/in??

[pingu]

A newton is about 100 grams; there are 454g in a pound. And 25.4 mm to an inch. Happy calculating!

As to which column, the two where it says N/mm!

[moonsspoon]

Sedan = 35 F 30 R
Touring = 32.5 F 35 R

[MBXB]

1 Newton-Meter = 0.73756215 Foot-Pounds

Cant vouch for the accuracy but this seems to be right up your street:

Thats ironic the australian was the only one confused by the metric units....
i searched in german also for spring rates but couldn't find anything apart from that page.

The column that shows the rates is the one that says バネレート F and R (front and rear)

[Barney Paull-Edwards]

Thanks fella`s, my starting point will be 230lb/in, got some fun fitting top mount but still cheaper and more adjustable than any other method.

[BigKriss]

yeah my mistake Rob. I honestly couldn't notice it the first time I saw the table.

yeah no worries, hope this helps out yourself in the quest for spring rates.
some of those rates are defined as
race version - ロアーバージョン
sports version - スポーツバージョン
or comfort version - コンフォートバージョン
as written beside the car type in the LH corner
