Does anyone else have problems driving on UK B roads with regards to ground clearance?
The car drives so well on these roads but progress seems to be limited by the front scraping the ground.... Has anyone damaged theirs from this or is it just the black blocks in front of the wheels that are causing the problem?
I find I cannot fully enjoy a B road blast as I'm always concerned about damaging the front - A roads are fine but what appear to be flat smooth B roads appear to cause problems

I spend most of my time on B roads and find its just the blocks scraping ,but only occasionlly.And im still able to travel at speeds far in excess of any other road car ive owned without scraping ,i suppose you just have to know the limits of your local roads by building up slowly

I have recently returned from a trip to North Scotland and the West coast where the car seemed to continually bottom out even on bumpy A roads. But I checked underneath and no paint damage just the loss of one front rubber deflector.


I was very surprised as I was convinced the underside was touching down.

Thats what I experience - it is a bit unsettling to the drive but when you check there is no damage. I can't help think that the force on the deflector must go somewhere and could damage the front wing if hit hard enough? I'm not sure what they are mounted to or if they are designed to scrape the floor? Do you think the front wing would hit the ground if the rubbers were removed?

They seem to be designed to be sacrificial as the replacement part is £20 or so and quick to fix.

Will the car bottom out?Will it damage? My guess the lower section is made of PU which will deform and recover after impact but I can't remember the threshold levels.There must be a force and impact that causes damage which I had thought I'd reached several times at speed but have yet to see damage other than loosing the deflector.

Same here,i used to suffer far greater damage on my 911 on the same roads at speeds at least 20 mph less,again i think its just a case of you travelling quicker than you would in a normal supercar and not realising and ajusting to suit.Also i find it helps to use the same peice of road at the same speed but in the different modes,then i get an idea how far i can push it on my way home;)

These black blocks are made of rubber. My dealer cut them 50% off and now they are not scrabbing the ground anymore. It's more confortable to drive the car. I took a picture after cutting the block. It's not a good quality but I guess you can see what I mean:

why not just take the blocks off?
They do give some protection and also a warning you might need to back off before doing some real damage.Also the main reason they are there is to help defect the airflow from the wheels and keep the airflow smooth for the rear diffuser! Im sure this affects high speed handling to some degree,maxeneddy did say after breaking his CF brake cooling duct even that made a difference

This is what broke off
Had exaclty the same happen to me last night - lost the left rear deflector as the car bottomed out at 3 figures - did notice a slight stability issue at high speed - red line fourth then into fith ;). Will get it sorted next time its at the dealer as its nearly 400 mile round trip,,,
