Factory intakes are notoriously restrictive
Ultra Race Series manifolds were developed using the latest in Computational Fluid Dynamics software and years of R&D with our legacy Pro Series Intake Manifolds to provide the ultimate modular solution to suit your needs
The finisher is made of carbon
Larger volume with inlet diameters of 78mm to 88mm (stock is 63mm)
and slight modification was necessary
Spoon Rear Camber Adjustment Plate, Street - Jazz/Fit GK5 Gauges Factory intakes are notoriously restrictiveThe rear suspension of the FIT3 (GK5) is a torsion beam type, so there is no adjustment mechanism for toe as well as camber, and so when the car is lowered, the toe is significantly in the IN direction. For FF (front wheel drive) vehicles, if the rear toe is extremely in the IN direction, the rear grip force increases too much and the car tends to understeer, which means that the cornering performance is poor. Therefore, SPOON conducted repeated tests
