H&R's sport spring is a complete four-spring set (front and rear) for the 1993–1998 Volvo 850/S70 platform, and listings for this kit include the T5R. The manufacturer's spring line is built from 54SiCr6 steel, which H&R rates at about 290,000 psi tensile strength. Owners in forum threads usually steer buyers toward H&R or Eibach rather than budget unbranded springs, so this set is the better buy when you want a known spring rate and a predictable ride. One owner who ran H&R springs with Koni Sport struts reported a firm but comfortable ride and a stance they did not want to lower further.
Application data points to sedan and coupe bodies, not wagons, so confirm your body style before ordering. Owners say the wagon uses a separate part number. Use this kit for a lowered street stance and better body control on a daily-driven or occasional track FWD Volvo, and confirm the exact front and rear drop with the manufacturer, since published figures vary. Search terms buyers use include "1993-1998 Volvo 850 sport springs," "S70 T5R lowering springs," and "H&R 29958 sedan coupe."
Owners on user forums report that the wagon uses a different H&R part number, so this sedan/coupe kit should not be installed on a wagon without checking the manufacturer's fitment list first.
Owners on user forums warn that Nivomat self-leveling rear springs are much weaker than standard coils, and that a lowering kit meant for one setup can drop the rear onto the bump stops when fitted to the other. Confirm which rear system your car has before ordering.
Front installation is a strut-type job that requires a proper spring compressor. Owners who have done it recommend compressing the coil before loosening the strut top nut, and they describe catching about six coils with the compressor so the spring stays seated. Rear coils are easier by comparison. One owner reports they can be swapped without a compressor once the rear suspension is allowed to drop fully, while another owner on a V70 found that the rear spring needed compressing and the caliper removed to reach it, so plan for both possibilities. Owners also note that the sway bar link, ABS wire bracket, and strut mount orientation should be handled carefully on reassembly, and that camber should be checked afterward by an alignment shop.
