I have no arch liners

[chrisJDM]

Got my new FD about a week ago, it has no front arch liners, is this gonna cause me a issue? the main issue i can see is the fact there is a hole into the engine bay so dirt and water will be chucked into the engine bay from the tyres

the arch liners also work with the brake vents... so direct air round and out...

and if the car is low, then ull eat into the wiring....might cause ur car not to start cos wiring to the ignitor runs there as does wiper wiring

You\'ll eat the wiring if the car is low anyways - a few 10ths of a mm of plastic won\'t stop the tyre eating through it

As said - they provide cooling for various things, and keep all the crap out the bay, I\'d suspect they also contribute to the aero on the front. I\'d be replacing them
