Hello all - Anyone have have any problems going over speed humps in the roads with a Boxster S? I'm picking mine up next Saturday, and it's just occured to me that there's loads of humps up my road - hope I can get it home! Didn't look to see how low it was!

Thanks for any replies

Nigel
 
Take yuor time and you'll be fine - one thing that is worth checking when you get the car though are all the black plastic flaps underneath - one either side at the front and two either side of central near the rear axle - these are cheap to replace (<£10 each) and are key to high speed stability
 
Our local OPC here in Glasgow is in the middle of a residential area. The locals campaigned for and got some big speed bumps put in at some stage (not sure if this was before or after the OPC arrived, but I can guess). Anyway, the sales guys are very keen to make you go very slow as you set off on test drives but they are fine.
 
Speed bumps should be no more than 10cm (4 inches) in height. They should be removed or lowered if taller than this.

I've never had any problems in my normally suspended boxster. However, inside edges of tyres can wear prematurely if you traverse a lot of humps by straddling them - obvisouly this applies the the mound type. I vary taking them on the left or right side and straddling to try and mitigate some of the tyre and suspension wear.

I believe there is a debate/choice over what speed should be used - slow and gentle, or fast and flying!
 
I've never had a big problem with speed humps, but there are the odd occassions when you come up to one a little too quickly (because of weather and visibility, etc, so you haven't seen it), break firmly, the nose goes down and you get a reassuring scrape from the front end.

Normally though, sensible speeds don't cause an issue.

Design directive from the Scottish Executive places speed bumps at 75mm high maximum.

Can't see these being much problem then - unless they have vertical faces!
 
Problem is, most are installed at 100mm and sometimes higher.

Depends on the ramp gradient also, thats where my Boxster skips each one on our road, single angled brick as a ramp. Useless.
 
Dead or Alive? Sometimes you see them lying in the road, been run over[:D]

Sorry - Welcome to the forum Chris - you have a very interesting first post! What do you want with them?

Welcome!!

You see the humps from time to time on FleeBay but beware the 'look-e-likey' ones tend not to fit very well and can mark the paintwork.

Also note that the Porsche ones are only designed to fit the 986 not the 987.
