Designed from a clean sheet, the new Wavetrac Differential brings current gear technology to the market. Internally, its gear tooth forms are optimized for strength and improved oil film retention over competitive designs. Our gear package is smaller, reducing overall mass, yet is more durable. Attention was also paid to the side gear/axle interface, putting as much material thickness as possible in this critical area - most important when power levels get high. Each Wavetrac Differential is crafted from the highest quality materials available. The internal gears are made from high strength 9310 alloy steel. The diff bodies are machined from case hardened steel billet. To complete the package, every Wavetrac differential is built exclusively using high quality, high strength fasteners from ARP, the world leader in fastener technology.

Wavetrac Review 2016 Fiesta ST
Unbelievable. The amount of additional mechanical traction you get from having this installed is like having another car pulling your car ahead of you. The day I picked my car up from the shop that installed it, it was raining for 8 hours beforehand. The car just hooks up and goes, its almost like having standard open diff all-wheel-drive. Its alot more stable when switching lanes quickly on the highway, deceleration is much smoother as there is no zero load moment after the clutch connects the engine to the transmission. The car is much smoother around 45 degree and 90 degree corners on smooth road in the rain.... where as before the outer or inner from tire would start spinning. Even when traction is lost, the car grips like crazy and the spin of BOTH front wheel is pulling the car forward. Tires on my car are Federal 595RS-RR 215/40/17 on OEM rims Protuned by Stratified on E30, dynoed at DB Performance in Rogers, MN on a Dyno Dynamics "heartbreaker" 196.2whp 300wtq (Stock was 176.9whp 207wtq) crank 218hp 295tq. Cobb Rear Motor Mount Stock OEM Springs front and rear Avg Cobb 0-60mph without the LSD is 6.4 second with above traction advantages. The LSD was installed with (2364-ATB-HW) ATB Differential Installation Kit, B299 Fiesta ST from Mountune which is very important as its common for some of the parts that are needed to install the LSD to brake during the attempt to transfer from Open diff to LSD process, it happened at the shop I had the diff put on. Whether you are tuned or looking to go Big Turbo eventually, or like to hit the track.... this is a must have mod for the fiesta st.
