Dial in pan car handling with XRAY 4.0 coil springs

For tuners who want precise front-end feel, the XRAY 372180 4.0 Coil Springs deliver consistent response for pan car setups. These gold springs are made for front suspension use and help refine handling without guesswork.

Fine adjustment for competitive pan cars

The XRAY 4.0 coil springs are built to give racers exact control over suspension compliance. By selecting coil count and wire dimensions you can tune motion, and the C=3.5 stiffness rating provides a neutral starting point for many track surfaces.

Easy ID and reliable finish

Each spring uses powder colour coding so you can spot the right rate quickly during practice or race day. The gold coating resists wear and keeps spring geometry stable after repeated use.

Are these springs a direct swap for standard pan car front assemblies?

They are intended for pan car front suspension designs and fit most common front assemblies, but check your shock shaft and retainer dimensions to confirm fit.

How does the C=3.5 number affect handling?

C=3.5 indicates a medium-stiff spring in this range, offering a balance between turn-in response and mid-corner grip for pan car applications.

Can I combine these with different rear springs?

Yes. Mixing front and rear spring rates is common to tune understeer or oversteer; start with small changes and test lap-by-lap.
