NOTE: This kit fits will fit all BMW chassis used for motor sports except for the e30 (we have another product for the e30). It`s built per order and will have a few weeks lead time. Please email us with your chassis / knuckle / diff combo before or after purchasing. With the advance of power in motorsports seeing a 1000+hp car with 1000+nm can be often seen. Our standard 720NM kit was not enough especially when adding a sequential gearbox in the game with lots of play and hits transfered thru the drivetrain. This is literally the strongest kit we can come up with and do believe it`s key features might impres you: - Stub Axle setup with 30z (33mm) spline size - 122mm inner and outer CV joints with more than 40mm travel featuring 30z (33mm) shaft spline size which is probably the biggest you will see in the motor sports market! - highest grade shaft material with spring capabilities allowing it to withstand multiple twists and deformation giving easier life and longer lifespan of the whole drivetrain What you will get: - 2 stubs with 33mm splines whith nuts to tighten in the hubs - 2 high end half shafts with 4 122mm CV joints necesarry hardware included - 2 adapters with bolts for the differential flange NOTE: This kit might have interferance issues with the factory E-brake cable and would require you to rework it`s path if you plan on having it. NOTE: A picture has been attached introducing you to the right way of how the size of the shaft should be taken. NOTE: This kit will have some interference issues with the bmw e36 and e46 upper control arm. Using a thru coilover setup with adjustable thinner than stock upper arm is a must! These are built per order and will have a few weeks lead time.
