I'm useing B16PSS10, current setting is Front 4 / Rear 4 (soft 1-10 stiff)
is it necessary to set the rear chock 1 level softer than the front or it's ok to be same ??

 

It’s okay to set them however you choose. It’s your car, and you can dial it in for either your comfort or however aggressive you want.

 

Ideally, adjustable dampers are set to the road conditions. However, that is not really feasible for a street car. What is nice about the Bilstein adjustable coilovers is the rear adjustment is exposed so you don’t have to remove the damper to make adjustments.

Here is a short but good article to help set your adjustments:

FYI, with single adjustable shocks, you are only adjusting the “bump” setting.

 

thanks !! this is exactly what I'm asking for, not like someone just posting meaningless comment of " it's your car you decide blah blah blah"

 

Ultimately it comes down to personal preference and vehicle response to driving style and conditions. I just gave you a guide how to figure it out.

 

It truly comes down to how you want the car to react or for how you drive. There are a ton of threads here on how people set up their cars and how it reacts. Read The one the ScottyR56s has going, great read, seriously 2 different people set their cars up to different things. I get if trying to get a baseline and going to dial it in from there.
