When I bought my 320 coupé I didn't think it was much lower than the 318 saloon it replaced but a couple of speed ramps have made me guess again. I do slow right down for them but in a few cases not enough. I hear a horrible thud as the suspension is compressed when the wheels reach the bottom. I haven't had a chance to crawl under the car to see what part is meeting the ramps, maybe I don't want to know! So, two questions I guess: 1. Is this normal for an unmodified E46 320Ci? The only way to avoid it is to stop when the front wheels are atop the ramp and eeeease down the far side on the brakes. 2. What is it that's hitting the ramps? It's very solid, so it's not bodywork. Is it a ball joint or wishbone, or am I hammering my sump and working toward a monster bill for sump, oil pump etc. at my next service? Posted here because of the wealth of knowledge and the fact the 3 series technical board seems to move slower than an asthmatic tortoise. Edited by milltown |

I hit a few of the really narrow sharp ramps yesterday (on the way into
Hilltop Quad) and something under the car was banging off the ramp also. I went over really slow and it seems that when the front suspension compresses the car hits the top of the ramp. Went over a little faster on the way out (like 5mph) and the car didn't bang off the ramp but if felt a lot harder on the suspension. Poxy ramps. |

I know of one place here in Ireland where there is a speed ramp in a 80km/h limit! Beggars belief! |

Try diving a E39 Mtech. The plastics on the front bumper get smashed all the time. If a ramp is in a 30mph zone then in theroy you should be able to drive over the ramp at 30mph?? not me 5mph. I like my car mister county council. Mick

Ramp just outside front door of B&Q Airside in Swords bottomed out the e46 compact every time. Even crawling along. Has anyone noticed how often you now see sill damage on cars, especially small ones? Seems to be most common on passenger side under front door. Speed bump related perhaps? |

There are speed bumps on the way to my car park at work... and they are very poorly designed so they make a sharp bump when driven over slowly. My car grounds out after my front axle has navigated the bump and there's a thump as the car gets back to normal height. This doesnt happen if I drive over them at about 15-20mph.
Any ideas what I'm hitting? (seems like something behind the front wheels) (sorry to jump in btw!) |

Looks like we all have cars that run too low. Shall we all chip in for a group buy on X5s?

You guys think you have problems... I have to slow down for the smallest of dips in the road. Not potholes, just dips. My car bottoms out in Mondello coming up to dunlop. http://www.e39m5.com/stuff/M5BottomOut.wmv Can't believe the roads I have to drive on considering the ammount of tax I pay a year.

Have a look at your pic above. The 'D' should be directly in the middle of the car. A bit anal I guess. Edited by flyingalexf68 |

eh... the white spaces on either side is equal, the D is not in the middle because the 1 takes up less space than the 9s and 0s. I rather have the spaces on either side be equal, look more symetrical I think.
