Why not ? Lowering a car nearly always makes the look better, more compact and especially classic English Sports Saloons benefit from a lowered suspension. Can´t see any reason, why it should not be achieved easily be shorter springs. Even the pullshock damper system works better from a lowered suspension, that´s my opinion, when I´m looking on these totally "unhealthy" damper position, when the front of the car is off the ground.
I´m sure, each 2nd BMW 2002 and each Dolomite´s suspension is lowered and if all components (see Peter´s advice) are seriously inspected or renewed, the driving experience is better. Treat the last sentence as a personal statement ....
I have to bring the car first back on the road, but I´m also one of these guys wanting a more compact (lower) look.
If the P6 would not have this funny front suspension, I would have done it earlier.
A perfect job was done by cobraboy with it´s individual adjustable suspension arms, which really makes sense. Maybe he´s working on small series soon
And don´t forget, almost every car manufacturer loaded his new cars with heavy weights to bring the car more to the ground, when doeing the advertising. Hmh, why ?
