Suspension Help Please

[keith baker]

I'm running a T30 kombi fully converted. It has VW sportline 40mm lowering on standard 16" wheels. The problem is that the ride is too harsh and I fear any pothole. I'm happy with the lowering and could go 10mm higher. Is it the B14 route for me or are there any alternatives? Weight is 1400kg front and 1120kg rear.
Thanks

B14 is a great option, I went from a T32 on standard springs and difference was night a day, so much better.
