Correct Suspension height

[Andrewkb]

Hi all,

 

While adjusting my coilover height today, I noticed that the front left and front right has 5mm difference.

 

3 ways I measure, which is the most accurate ?

1) From top of strut tower to spring perch (see attachment)

2) From bottom of screw thread to lower spring perch

3) From center top wheel arch to the floor (According to TEIN measurement is top of wheelarch to center of rim, but I just measure to floor easier)

 

I am currently using #3, and ensure the 2 sides are of the same height.

 

Question is, am I right ?

 

However, some people mentioned that 5mm is too "minimal" to be bothered.

The only correct way of measuring ride height is the distance from the wheel arch to the centre of the wheel ie:your rim.

That;s what TEIN manual said .. but from top of arch (never roll before) to center of rim vs to floor, the same right ?

you floor might be uneven.

anyway a difference of about 5mm is common as maybe your inflation of your tyres and other suspension components might cause this.

TEIN is right... Coz your tyre plays a part in the height if you measure to floor.
