The H&R 29526-2 is the manufacturer's Sport Spring coil-spring lowering kit for the MK4 Volkswagen Golf and Jetta. The manufacturer lists it at approximately 1.5 inches of front drop and 1.4 inches of rear drop, which lowers the center of gravity and reduces body roll for sharper street handling. It sits one step above the OE sport spring, which the manufacturer lists at about 1.0 inch front and 0.5 inch rear, so the stance change is far more pronounced than factory sport hardware.
Choose this kit over stock springs when you want a measurable stance change without the cost of a coilover system. The manufacturer positions its race spring (29527) at approximately 2.0 inches front and 1.75 inches rear, so this sport spring suits owners who drive mostly on the street and want firmer control without a race-level ride. The manufacturer's application listing covers 1998–2005 Golf MK4 VR6, TDI and 1.8T models. Confirm your Jetta's engine and trim against that listing before ordering, because fitment details are not consistent across sources.
Searchers looking for an MK4 Golf VR6 lowering spring, a 1.8T MK4 Jetta sport spring, or an H&R 29526-2 versus 29527 comparison will find the drop figures and application notes above most useful.
