How low do I go?

[p4uke]

Hi

I’ve just bought some 15” BBS 7j’s for my 1983 e21 316 which currently has standard suspension. Obviously it needs lowering as at the moment I can fit my head in the arch.

What I would like to know is can I just replace the springs or do I need to change the lot?

Also, how low do I go? I’ve seen some springs available with 40mm drop and 60mm

I've always worked on the idea that a 40mm drop on standard suspension is OK. 60mm+ drop u should look into upgrading the shock too

Just my opinion don't take it as gospel

The 7J wheels at the front may give you issues (rub the fenders and cause damages) if your dampers aren't too fresh, or if you go lower than 40mm drop. I would not fit wider than 195-wide tyres at the front which is also Alpina spec.
