Bilstein Heavy Duty struts

[DWBOX2000]

I will replacing the front struts on my 2000 Boxster S in a couple weeks. The rear has Heavy Duty (HD) put in by previous owner. Why would someone do HD instead of sport, is it height related? Would HD keep it stock height? Am I Correct to assume that I should get HD in front to maintain the same height? Any other parts I will need or should it just be swap out, swap in?

Thanks,

David

What type of driving are you doing? Do you take your car to the track once in awhile? Is your car a daily driver?
I have PSS10 Bilsteins on mine and it bounces around like a "happy rabbit". I also take it to the track.
When I drive it on the streets and roads my back at the end of a ride kills me. It's a very hard ride.
Maybe you should direct your question directly to Bilstein or wait until someone from Pelican, with more knowledge, answers your question.
On the matter of height it all depends on you. If you lower your car you will suffer the adversity of hitting your oil pan on manholes and other types of obstacles on the streets and roads. Also remember, when lowering the height of the car, your center of gravity changes also.

I don't think you should use struts to adjust the height of the car, its in the springs.

I want to keep the car stock height. I just do not know what bilsteins to buy for the front that will keep the car level. Currently Bilstein HD's in back with original Porsche struts in front.

I plan on doing some autocross in the future but not enough to warrant changing the way it rides.

Thanks,

David

As steven states, the shock/strut control up/down movement, the spring provides the platform,...simplistically stated. The difference between HD and Sport has traditionally been the length of the piston/shaft. Sport is typically used with lowering springs so the shaft is shorter. HD typrically has a longer shaft to be used with OEM springs,...or springs that lower slightly. This, unfortunately is not always the case. I have an '88 911 and the car has HD on the front and sport on the rear. I think the sports are a bit stiffer but not easily noticeable.

Finally, Bilsteins are gas pressure, so there is very subtle upward pressure which could raise the ride height VERY slightly when used with your stock springs.

fwiw.
