I have my car pretty low and the little plastic flaps in front of the front tires on an AP1 scrape on any and everything. I do not know if this is the right place to post this but do those flaps have any aerodynamic significance? Or can i just take them off and ditch them.

Thanks

 

Took mine off, took about 3 mins. I never saw the point of them and they look funny.

 

it direct incoming air around instead of letting it hit straight into the tires.

yes, there's a very meaningful purpose for it.(unless you are a hardcore autocross fan with on a car diet)

 

that funny looking thing works, you see a similar flop under alot of american car for the different reason.(to create high pressure zone under the car to pull alot of air into the radiator to achieve max cooling)

 

I think I hit 65 on the highway for about 1 mile a day. 1" worth of plastic aerodymanics isnt my biggest of concerns

 

I realize they have a purpose was just wondering to what extent it would affect driving. Its no big deal though its just a little bit of plastic scraping I guess ill just leave them on. I appreciate the replies.

 

Unless you go 100+ on a regular basis I really cannot imagine you would ever notice a difference, other than looks and scraping noise.

 

um...not sure how should i say this but, yeah, i am just trying to correct common myth around the forum. the truth is there's a purpose for it and we don't know how effective it is(well, let's say at least i don't, since i am pretty dumb). that is the truth, but if it's concern the engineer enough to put a few gram in from of the car, iMHO it's worth keeping there.

also, the size of the flop is relative to the location and speed of the car, one inch is not much but one inch of flop can create alot of changes if the placement and speed. NSXr has an antenna retract swtich to lower the antenna to lower the air drag co-effiecent(the circumference is only what? 3/8 of an inch?)

i almost feel like doing a physic problem for this.we know the size of the item, the velocity(let's say 45 vs 100 km), air friction

again, not trying to offense anyone nor i am trying to tell anyone what to do with their car.

 

It's not the straight line difference you'll feel. It's track stability. Air is a "fluid." With the flaps, the air is directed largely down regardless of which way the front wheels are turned. Without them, imagine driving through standing water with the wheels turned. Plowing through "fluid" will induce more oversteer. Transitioning from side to side might also contribute to "throwing" the car into oversteer and feel less stable.

 

Currently they server the purpose of letting you know 1 inch before you bottom out.
