Product Details

The Wilwood FDL Rear Drag Kit is a complete bolt-on disc brake solution engineered specifically for sportsman category drag racing and muscle car applications. This kit provides full-function four-wheel disc brake capability for vehicles competing in classes where weight reduction and reliable stopping power are critical.

Key Features:

  • Forged Dynalite four-piston calipers for consistent, fade-resistant braking performance
  • Drilled 3/8-inch thick plate steel rotors to reduce rotational weight and improve weight distribution
  • Lightweight aluminum hat mounting system secures rotors directly to the axle
  • True bolt-on installation designed for popular muscle car rear axles and custom aftermarket axle ends
  • Purpose-built for drag racing applications where every pound matters
  • Complete kit includes all necessary mounting hardware and brackets

This drilled rotor version offers additional weight savings over the standard solid rotor configuration, making it ideal for racers in classes with strict weight requirements. The four-piston Dynalite caliper design delivers balanced brake force and consistent pedal feel, while the precision-engineered mounting system ensures proper alignment and secure installation on a wide variety of rear axle housings.

My name is Doug Raber and I tell you the truth when I say autoplicity is a great site to shop for auto parts. The prices are low and the customer service is excellent.

Very good. Easily found what i wanted

Excellent price on the product and shipping! Ordered on Thursday night (after they closed) and they were shipped out Monday!

First time I've tried these guys. Had trouble getting this product from my normal source (backordered) but Autoplicity shipped quickly and had a better price too! You know I will be back! Thanks!

I searched for a quality automobile battery charger and found the best priced and longest warranty "smart" charger at Autoplicity and one other seller. Autoplicity carried a wider selection of the models offered by the manufacturer.<br> Looking over the website I entered my vehicles into the fields and found quality offerings. It is worth looking at.<br> Ordering was straight forward, shipping began the next day with a tracking number, and the order arrived on time. I bookmarked the website.

Great price, fast shipping and the items was correct. A perfect transaction. Thank you!

I received my ARP head studs as described and on time with zero problems, and cheaper than anywhere else.Will use again!!!
