Great product, very smooth unlike some bodykits, my body guy was amazed on the product said will have it done sooner than thought, I did tho however have to drill 2 holes where the side markers go, but easy enough, everything else matched up and fit perfect to all the body lines very easy do it yourself. Amazing kit very pleased

I bought the prodrive-style front lip for the 02 wrx.Between order-complete to lip at my door was < 4 days. The product is legit and of decent quality. The packaging was great and the lip itself seems to fit really well. As cheesy as it sounds, I am glad I bought from ilovebodykits.

The exhaust sound really good. Installation is straight forward. Thanks
