Spring for CF bonnet

[jhonson3141]

I do always wonder, after gone for a pretty CF bonnet, the spring force will need to be lower to fit the lighter bonnet, but how hard can it be?

the origin spring force is 350n and i figer if i can get a 200N or lower it will be good, but after i've looking into most of the springs are 300N+. I have search the forum and tried the m3 spring, wich is 1cm longer in full compression. So basically i can close the bonnet but cant lock it.

can any one suggest a spring that can fit my case? i,e the full compression length is shorter than oem and force is lower than 200N


the bonnet is a V_style bonnet made in taiwan, fitment is good but due fit on 120kmh+

I believe the shock for an m3 with an aluminum hood is what most people are using for this.

I tried m3 hood shocks too and it was too strong too. Anyone know If the e90 shock different than e92?

What other options do we have

I use the m3 shock- works well with my CF hood
