Boxster Shock Absorber & Suspension

Recommended Posts

Hello, good day ! :welcome:

I owned a Boxster 98 - 2.5, I feel the shock absorber a bit hard and bumpy while normal driving. I guess, time to change the Shock Absorber after so many years. I want a combination suspension, which I can enjoy normal comfortable driving and sometimes I will push for hard driving.

Which is better ? Coil-over or original absorber ?

What is the difference between coil-cover & original shock absorber ?

Blistein PSS9, K&W colilover, H&R coil-over, which is better in term of cost, performance & normal driving ...

I ready appreciate anyone for the input. :renntech:

Thank a lot.

Technically, the stock suspension on a Boxster is a coilover since the shock assembly mounts through the spring. However, the term "Coilover" is typically used when a suspension has adjustable ride height. Normally this is achieved with a threaded shock body like the PSS9 and H&R Coilover systems.

You don't mention your location. Here in the US, a popular upgrade is to install an ROW M030 (Rest of World, Sport tuned) suspension. If you are not located in the US and your car does not have the M030 suspension, that is probably your best bet. If you go that route, I would also recommend upgrading your swaybars to the M030 bars too.

If you drive your car 100% on the street, I would recommend simply replacing your suspension with either OEM or aftermarket stock replacement parts. Bilstein has a couple of standard shock replacements as well as their PSS9 system you mentioned. I would be hard pressed to recommend a coilover system unless you are autocrossing or tracking our car. Even at their softest settings, you may find the ride a little harsh.

Good Luck,
