Kerb weight in relation to coilover height

blackster · Postby **blackster** » Tue May 13, 2008 9:29 pm

After measuring the OEM height I have noticed that passenger side sits about 5-6mm lower then the drivers side, putting mwah in the drivers seat makes D & P height about equal.

Is kerb weight considered when setting P & D coilover height? If so, would you apply the same principle when setting the height with aftermarket coilovers.

Cheers

P = passenger side
D = Driver's side

Seeming you have coilovers you can cornerweight the car.

Did you buy coilovers Phil? If so, what did you get?

Corner weighting (if i can use that word) as i undestand it attempts to provide even weight distrubtion to stop the car from wedging or reverse wedging. The process of going about it seems a bit of an overkill for a street car.

I am wondering if whether mazda deliberatly from factory adopted corner weight principles, as un even height; which is noted affects weight on that corner. Perhaps the placement of the battery in the right rear also serves a purpose other then being placed there because of a lack space.

You have a very rare car there Blackster. 99% of vehicles would be lower on the drivers side than the passengers, especially once they start to age.

Care to share the reason why? Apart from having a driver that surpasses "kerb weight"

Yep, overtime that great lump of dead weight located amidships of the car (the driver) causes the suspension to settle/droop/drop/sag on the driverâ€™s side. Race around to a few cars with a tape measure and see what I mean.

I'm NOT saying there's more unladen weight on the drivers side, just that most vehicle without the driver are down on the drivers side. A lot of people swap sides with their springs when replacing their shocks in an attempt to have the car settle evenly over time.

Sâ€™pose if you think about it, it would mean that the car is level when the camber of the road is taken into consideration. :roll:

PS Out of the factory mine was 5mm lower on the right rear than the left but the fronts were within 1mm.
