I'm trying to figure out a safe way to lower the car's ride height (front and rear) without having to source the JLR SDD cable and software.

I tried shimming the front height sensor 2.5mm, which did lower the car, but lowered both the front and rear I wanted to lower the front only.
I was hoping to have equal wheel gap front and rear, as of now I have 3 fingers gaps in front / 2 in rear.

Has anyone been successful in 'manually' adjusting the ride height via shimming or other methods?

 

the front sensor shouldn't effect the rear should it?

 

I've been wanting to do this with the shims also.
Does anyone have an idea of how much drop per 2mm of shim produces?

I read that the rear might require less shims for the same amount of drop?

There was a promising thread regarding modifying the signal to the sensors but it died without any answers. It seemed like you could install a resistor inline that would modify the signal. Having that on a dial would be awesome but its beyond my technical skills to create something like this.

There is also a module that you can buy from arden that uses the sport switch to lower the car. but its terribly expensive.

 

This was certainly my assumption, but it ended up lowering the rear as well. Im not sure why..
2.5mm shim in front = approx 1/2" drop.

 

The easiest way to to alter the voltages
Remove the back seat rest and fit resistors to the 3 or 4 sensors

The easy way to work out the values is to use a resistor wheel on each sensor

Easiest way is to bend the brackets slightly up? if I remember...I lowered my front 1/2 inch in 20 minutes!
