The H&R 29749-2 is a progressive-rate sport lowering spring set for the Mercedes-Benz W202 C-Class, covering the C280 and C43 AMG built after June 1, 1996. The springs are made in Germany from 54SiCr6 spring steel, shot peened and block set, so they resist sagging better than the soft factory coils. Lowering the center of gravity reduces body roll and sharpens turn-in, and the progressive rate keeps the daily ride comfortable. Owners on user forums commonly pair these springs with factory spring pads they have measured and swapped, so check your pad set before you install.
Fitment is the main thing to verify. Part 29749-2 is the C280/C43 kit, not the 29749-1 kit, which is sold for the C220 and C230 W202 with a different application. Year coverage for the C43 AMG is listed differently across sources, so confirm your VIN and build date before ordering. Searching for W202 C280 lowering springs 1996-2000, C43 AMG W202 sport springs, H&R 29749-2 install, and W202 fender gap lowering will bring up the right comparisons. The DIY difficulty is moderate. The front coils need an internal spring compressor, while the rears are easier to remove after disconnecting the lower control arm and supporting it with a trolley jack. Plan on a wheel alignment after the install.
Owners on user forums report that the front springs require an internal-style spring compressor, while the rear springs can be removed by disconnecting the lower spring arm on one side and supporting it with a trolley jack.

No. The 29749-2 is the kit for the C280 and C43 AMG W202, while the 29749-1 is listed for the C220 and C230 W202. Compare the part number and vehicle application before ordering.
Plan for a moderate DIY job. Owners on user forums recommend an internal spring compressor for the front coils and a trolley jack to support the lower control arm on the rear. After the springs and any new pads are in, drive the car for a few miles so it can settle, then have the alignment checked. Inspect the front spring cups for rust and clean them before reassembly.
