Hi,
Anyone know what lowering springs to use on a BM diesel?
No direct listing for this model by the usual manufacturers. I can get a good deal on Prova springs (for OEM struts) but cant decide from the spring rate options...
31144 TH 1010: DIT BMG 2.0 sedan
Standard height ratios: f =-25 R =-17 (mm)
Rating: F=3.85 R=3.89(kg/mm)
31140 TH 1010: BM9/BMM 2.5i/2.5GT sedan
Standard height ratios: f =-30 R =-20 (mm)
Rating: F=3.90 R=4.30(kg/mm)
why is the 2.5 stiffer in the rear?
