So speed bumps here are a pain, I take most of them sideways whenever I can but you always have that speed bump on that road that doesn't have enough room for you to maneuver. Anyways I check the bottom of my car and its not the bottom of the body thats getting scratched, it has more than enough room to handle those speed bumps. There is some metal bar like things behind each tire, its diagonal, and thats whats hitting the speed bumps. I asked the guy at our mclaren dealership and he thinks its to protect the car from being damaged from things like speed bumps.

Honestly that doesn't make sense to me because if it was to protect the car from bumps then the bar should be from beginning to end which it isn't. I am sure you guys know what I am talking about, so these metal things under the car behind each wheel, what are they for?

Not near the car at the moment,but the only thing under the car that im aware of are the airflow deflectors that guide the air down the centre of the car and away from the wheels to give smoother airfolw and hence maximum downforce,and i thought they were a rubber compound,but i might not be thinking ot the same thing

better than the side rocker panels getting nicked.

Yes I agree its definitely better than anything else getting damaged, but I think your right Andy they are airflow deflectors, I guess if they can damaged to much they can be replaced or something. I will try to minimize driving on small roads as those are the ones with the speed bumps that cause problems.

Unlike on the Ferrari/Lambo I find with the Mclaren it doesn't make a difference going over speed bumps sideways - its still bottoms out.
There is one road near my house which doesn't look too bad but no matter how I've tried the car won't get over the bump without scratching

Would it make a difference if you had it in track handling,Maybe its just a few mill out and a stiffer car might help?? Probably not but worth a try.

The pieces you are speaking of are made out of a hard rubber compound - I know because I busted one. My dealer told me that while going diagonally over speed bumps helps to keep from hitting the splitter, it ends up putting more force on these rubber pieces.

I'm going to stick with the diagonal approach because rubber is cheaper than carbon fiber.

Thats definitely good to know, but for me thankfully going diagonally on most of these speed bumps even prevents me hitting that rubber part, its going straight that actually manages to scratch it. I wish they had the same feature that was in the LP640 we use to own, with the push of a button it somehow raises the car a few cm to be able to tackle any speed bump lol.

I just patented (two weeks ago) an aerodynamic system that deploys under the body and automatically adapts to the road surface. The aero bits can literally go right to the floor and they will not impact the road. They are also completely compliant on impact with objects on the road. I've had the system built onto my Elise and have just begun testing it at the track. No issues even at 120 at Willow Springs. I've tried contacting McLaren through emails, but get no response from them. If any members of the forum know an engineer or other appropriate person at McLaren I'd greatly appreciate your help getting in contact. McLaren ultimately might not be interested, but I know it's something worthy of their attention.

Sounds interesting,just keep trying!,i only know the customer services and sales teams,i know an ex engineer,but he works for a different team now,but just a contract guy,not the in the main loop
