Bc Br Vs Hsd Hr/ad Spring Rate Interchangeability

[Pattey21]

Hey guys im looking at these three coilovers, for my daily r33 but are wanting spring rates as close to 6/4.

Ive been contacting a few suppliers but i cant seem to get an answer regarding how much i can vary the spring rate while still keeping the dampeners effective.

Bc is 8/6

HSD HR 8/7

HSD AD 7/5

cheers

Well the closer you are to the original rates the less concern you would have but basically there isnt a problem with the 7/5 or 8/6 either.

Why not get some Bilsteins and use the rates you want to?

[Pattey21]

Yeah true really want the ride height adjustability i know you can get that with bilsteins too. Just trying to see if anyone else has opted for lower rates on these coilover or equivalent and how they went.

BC also offers 6/5, at least here in the UK.

6/5 was recommended by them if you want a more comfy ride.

HSD AD is great for the street. Even though they are 7/5, they are very comfortable for the rates (dampening I'd say). Bum-on-seat experience in my mate's S15. He has the dampers up past half way as well.

Im currently looking to change springs on my Cusco Zero 2R - i assume you can use any spring being the same diamater

16kg front n rear are no fun on Sydney roads....

I think Hanaldo or someone else from wicked witch land had a thread on doing that to the same coilovers recently (Cuscos). Have a little search.
