H&R's 29513-2 is a front and rear sport lowering spring set for the 1998–2004 Porsche 911/996 C2 in Cabrio and Targa body styles, 2WD. User forums describe it as a 1.25-inch drop at both ends, enough to close the wide wheel-arch gap that stock suspension often leaves on these cars. Owners on forums also call it a clear step up from tired factory springs, though some find the ride firmer than stock. Many pair it with Bilstein B8 dampers, and owners say that combination feels more settled than the springs alone. For buyers searching for a 996 C2 Cabrio sport lowering spring, 996 Targa H&R sport springs, or a 1.25 inch drop setup, this is the C2-specific part number. It is not the C4 set.
Installation is a serious weekend job. Owners report that the front struts come out through the wheel wells, and the top strut mounts are reached by removing trunk-side panels and the rear seat panel. A 21mm strut nut tool is the one special tool owners recommend, along with a full set of metric sockets, a torque wrench, and penetrating oil. Owners describe removing both rear sway bar end links and working the lower rear strut bolt free, which can take some persuasion. Rear sag is the most common complaint in forum threads, so check ride height on both axles after the install. For 996 Porsche lowering spring installs, the fitment years listed for Targa models vary by source, so confirm your exact chassis and model year before ordering.
No. User forums note that H&R splits its Targa and Cabrio sport springs by chassis, with 29513-2 for the C2 and 29466-2 for the C4. Confirm your model before ordering.
Opinions on user forums differ. Some owners say the ride turned bouncy with factory shocks and settled after switching to Bilstein B8 dampers, while others have run the springs on stock shocks without issue. The manufacturer's guidance on damper pairing was not confirmed in this research.
Some owners on user forums report that the rear settled lower than the front, with one describing roughly half an inch of difference. Owners have described adding a spacer to the lower rear spring perch as a workaround. Check ride height on both axles after installation.
Owners rate this as a moderately difficult job for a home mechanic with solid tools and jack stands. Per owner write-ups, you will need a 21mm strut nut tool, metric sockets, a torque wrench, and penetrating oil. Front struts can be compressed with a floor jack and heavy zip ties before loosening the top nut. One owner lists about 80 Nm for the top strut nut, so verify the torque against the service manual. Rear struts require removing both sway bar end links, and the lower bolt can be stubborn. Owners say the springs do not need trimming of the bump stops, but check the data sheet included in the box.
