Quick question for you guys. I'm pretty confused on what springs and coilovers I can put on my F54 All4. On ECS, the BC Racing BR series state that they can go on the All4. However, BC Racing says that they do not have coilovers for the All4, just the FWD.

Is this just due to a vehicle weight and spring rate thing, or will they physically not fit?

Edit:

Mike from ECS contacted BC Racing and they said that their coilovers will fit the All4. This is contradictory from what Tony at BC Racing told me. I guess I'll just keep you guys posted during my install.

 

FWIW, I just ordered the new ALL4 specific springs from AST. ASTLS-19-75. Will pair with Bilstein B8s, the NM Eng 25mm rear bar plus the KW DDC delete modules.

I’ll report back this summer when it’s all installed.

 

I have a suspicion that somebody mistook All4 for Dynamic Dampers or something like that. Of course you can't swap coilovers and springs on cars with the DD option.

 

As a follow up, the coilovers work perfectly and Tony from BC is full of dog *****. That is all.
