The best place for D4 Parts! Stocks are slowly ending but there are still a lot of parts that can be found here, that aren't available anywhere else!! 100% Recommended, actual retail prices, the shipping is fast (around 10 days) and decently priced

How does the diffuser influence slip angle and drift control?

The diffuser increases rear downforce and reduces flow separation under the chassis, which helps maintain rear contact patch stability. Expect cleaner transitions and more predictable slip angle behaviour when tuned with rear toe and damping.

What setup changes should I consider after fitting?

Begin with small adjustments: raise or lower rear ride height in 0.5 mm steps, check roll centre and rear toe settings, and recalibrate throttle input to match the new rear bite.

Is the diffuser compatible with tuning parts and rear wings?

Yes, it complements rear wings and other aero elements when used to achieve balanced downforce. Coordinate wing angle and diffuser clearance to avoid overloading the rear axle.
