PDCC Lowering Compatability
Hi Guys, I realize that there are so many ways to lower our cars with springs the most economical and quick way to do so. However I have been researching and found ( correct if I am wrong) that PDCC equipped cars can run into issues when lowering with springs. I was going to go with B16 Damptronics that is PDCC compatible but found that lowering is limited to 40mm and with my already 10mm pasm drop doesn't leave much room for a bigger drop considering spending over +3K for the kit.
KW HAS comes into mind that is around 1.6k and is PDCC compatible and gives you 35mm drop so with 10mm pasm an extra 25mm which is higher than the B16 coilover but also half the price.
My question is H&R springs gives a 30mm drop so that makes an extra 20mm but only for 300 bucks which is very cheap but will this cause any issues with PDCC?
Many thanks

The labor to install B16 damptronic, HAS and H&R springs will be the same, therefore, the only real choice is going to be the adjustability.
I have ridden/droven all three setups. HAS feels no different than H&R springs, B16 damptronic is definitely getter performing.
The only real issues you run into lowering is 1.) ground clearance, 2.) will need a good alignment 3.) amplifies the wear OEM offset and makes you want to run spacers.

Never had a single issue in 3 years with H&R springs, car rode perfectly fine and when I move them to turn the car back in from lease, it rode perfectly fine on the OEM springs.

On the cars that sit 10mm lower, expect an extra 25mm (1") drop with H&R springs. With the HAS or B16 damptronic you can go much more than 25mm because of the adjustability.
Here's what the H&R look like at the lowest setting on my car.

No, not at all, the OEM extra 10mm drop does not even come from a different OEM spring height. The extra drop comes from a movable lower spring perch.

My car had PASM/Sport Suspension. No PDCC or torque vectoring.
H&R lowering springs work with PDCC, the H&R VTF adjustable lowering springs are not compatible because of the PDCC front sway bar end link.
