But if I want to reduce body roll overall, would it make sense to upgrade the bars front and rear?

random question and I dont mean to thread jack, but do bilstein pss lower the car the same amount as the pss9s? Do the pss have external reservoirs as well?

They have the external reservoirs, and IIRC the PSS go slightly lower than the PSS9.

I don't think the dampers are physically different other than the adjustable shaft. The rears have piggyback reservoirs, just like the OE rears. This is likely done to increase the travel of the damper by moving the floating piston from the main body to the reservoir.

I can take some measurements of my PSSs, if someone else wants to measure their PSS9s.

thanks for the info guys, im pretty much a newb when it comes to REALLY understanding suspensions, but when people speak of "revalving" their coilovers, what does this entail?

PSS Measurements -

Front:
Lower bolt center to bottom of perch threads = 11 3/8"
Lower bolt center to top of perch threads = 16 1/8"
Usable shaft length = 4 1/4"
Top of usable shaft to lower bolt center = 21 1/4"

Rear:
Lower bolt center to bottom of perch threads = 7 3/8"
Lower bolt center to top of perch threads = 10 5/8"
Usable shaft length = 5"
Top of usable shaft to lower bolt center = 16 5/8"

To answer the revalving question...

Instead of trying to write up a response about damping and it's roll in the suspension, it's probably best for you to do a bit of reading from decent resources.

Give those a read through or two and they'll probably get you pointed in the right direction.

I'll stick to what I said before. Get which ever of these you want an then if there is still too much body roll get a front bar and if under steers too much after that get a bigger rear bar or wider front tires.

i don't see bilsteins for s2000s at AutoPartsWarehouse.com???

do you guys have the link for the pss9? is it out of stock? i've been hearing rumors they are getting scarce in the states.
