Spring Rates

[Gowf]

you dont need a tensometer to measure spring rates. You can calculate them from measurements of the spring

[bradc]

B8 shocks and bilstein springs of some description

[MYKEY]

I have the standard spring rate at home but not here.

I dropped my Bilsteins into Autolign and they are going to build me up a custom set, will be interesting to see what they think is best. The Bilsteins were 4.5kg and 2kg which means they must have been designed for a 2wd 1.8 Galant!

Just out of interest Brad, do you have the standard spring rate info, only ask as i am looking at my options with regards to springs/shocks combo or going for coilovers.
It would be helpful to have the the standard rates to get an idea of how much harsher different rates will be, cheers

[bradc]

Stock is about 4kg and 2.5kg for a Legnum, I think Galants are slightly lower in the rear. If you move to a lowering spring though you must increase the spring rates substantially, otherwise the car will bottom out.

Have you had the new springs made to match the B8's Brad? What did the rates end up being?

[Gly]

11kg f and 9kg r i believe, they recommended pretty much what the tanabes come with

[Kenneth]

I am very happy with 12kg front and 8kg rear in my Galant. Even Jo is happy being a passenger. Just gotta make sure you can adjust the damper rates right down when around town.

[bradc]

Yeah something around that spring rate. I forget exactly what though.

[twisted32]

So how do they feel now Brad?

[bradc]

Good

To conclude (nearly) this thread, about a year and a half later

I am going for 10kg front, 8kg Rear - Parts required for this are.

1 x SV100-01225 Front Springs
1 x SQ080-01175 Rear Springs
2 x CR019-01080 Helper Springs
2 x USS01-95585 Spacers

Fronts arrived today - The rest are in the US, making use of a colleague to purchase and ship them.

How much does this setup come to, if i may ask?

[BraindG]

The springs are about £200 - I'm getting them from the states, via a colleague - The price is considerably cheaper than TEIN UK/Japan - Although, the part numbers are a little different - I will post up once i know the US part numbers.

[VR457]

Thanks for that. Is the drop the usual Tein, 25 or so mm?

[VR457]

Can you give us any updates on these, whether they are part of a coilover setup or can be used with normal dampers?

[BraindG]

Nearly 2 years after posting original thread....

TADAAAA!!!

[BraindG]

Erm, do helper springs go at the top or bottom?


Google seems to suggest a mixture, saying that I can't seem to fit them at the bottom as the dust covers are in way.

Does it matter?

Cheers.

[adaxo]

Mine are fitted at the bottom

[BraindG]

Cheers Adam, mine will have to go at the top, the spacer doesn't fit over the dust cover thing.

Hopefully get them on he car tomorrow!

i fitted my helper springs at the bottom.
