what is the easiest way to adjust coilovers? right now i jack up one wheel at a time remove the wheel adjust so on and so on

 

You jack up one wheel at a time? You don't have a pair of jack stands? Have either the front or rear lifted at a time and go from there. No need to lift each corner individually.

 

no i just want to know how people do it my friend on his car dosent even jack it up he drives it on those ramps and twists

 

haha yea im lazy.. i just jack my car up and go underneath and twist. No need to take the wheels off....

 

see i tried to get up on those ramps but i cant get to the coilover to adjust

 

well for the front i just full crank my wheels left or right and reach. but the rears i jack it up from the subframe.

 

any more quick and easy ways like steezys?

 

It's usually better to jack up either the front or rear if you can, that way the swaybars aren't loaded and it makes adjustments easier.

 

Has anyone ever experienced a significant difference between drivers side and passenger side spring preloads when trying to set ride height? By this I mean that the spring on one side requires more preload to achieve the same ride height(force) as the spring on the opposite side?

 

no both side feels the same for is350

 

It's not unusual to set the front driver side height higher than the passenger side. The weight of each corner of the car varies enough to throw off your wheel gap. This is why guys with lowering springs are often left with less wheel wheel gap on the driver side than the passenger side. The springs are made the same so corner weight is not compensated for.
