Why NEOPRENE well I was looking for the best material that can take all the seasons up here in Canada and handle all the crap we put on the roads all while being sturdy yet malleable for every kind of car, whether they be stock high, lowered or SLAMMED to the pavement.
Now a little about why they are expensive.
The cutout for each flap takes time to cut on the machine. Also they get powder coated as well. This all costs money, and it isn't cheap. Oh yeah they are cut from STAINLESS STEEL. Why stainless well because Canada roads are the worst in the winter. Price MAY go down slightly as I am looking into a thinner stainless but that will be dependent on the testing phase.
If you buy these all I ask you to do is
1) Put them on your car
2) Use them normally
3) After a couple months send me pictures and any suggestions/issues you had with them.
4) Understand that they are a PROTOTYPE so if there are problems this is why and it should not reflect me or my companies quality.
Get them at this reduced price and maybe you will luck out with the deal of the century!
