I bought this together with all the other chassis mods for my 9-3 Aero. This was my last mod, so that might have been the reason i didn't feel a great difference. Regardless i believe, with further testing, this have made a difference.

The finish of the product was great.

The instruction video and gallery pictures made the install quite easy.

I can recommend this product!
