you can use the 3540 if you don't want to install the 4040

Doesn't the 3540 valve shoot a bit less fluid then the 4040. Why will waste the rear pads faster

why would the 3540 wear pads faster? it's sending less pressure to the rears, so technically wouldn't the rears last longer? and the car would be more front biased?

So the best way to go is the 3540
Can I use my stock camber arm?

You will only use the trailing arm itself, all the arms will need to be from your civic.
