I purchased a ducktail spoiler and front lip from WBS, and I couldn't be happier with the experience. The quality of both products is amazing, and the customer service was absolutely first-rate.
I also chose to have both parts installed, and the work was completed to an exceptionally high standard. Everything fits perfectly and looks fantastic. I highly recommend WBS and would definitely use them again in the future!

Can’t say enough about the customer service from Emad and quality of products . Can’t imagine how anyone could justify going anywhere else. Does wonders for the look of the M cars and very competitive pricing. Absolute 5 star total experience! Absolutely top notch fit and finish at least as good as BMW’s limited carbon fibre.
