The H&R 50145 is a full set of progressive-rate Sport Springs for the 1994-2001 Acura Integra DC chassis, covering non-Type R cars. The manufacturer's application listing gives an approximate drop of 1.75 inches up front and 1.5 inches in the rear, which lowers the center of gravity without moving into race-rate firmness. It sits in the middle of H&R's Integra lineup, above the milder OE Sport set that the manufacturer lists at roughly 0.75 inch front and rear.
Stock springs leave a wide fender gap and let the body lean through corners, and this kit addresses both while staying comfortable for daily driving. Owners on user forums report that the stance and cornering stability improve noticeably, and some have added a rear sway bar alongside these springs. Shock condition matters, though. Forum owners disagree on whether factory dampers hold up after lowering, so a shock upgrade is worth budgeting for if the car sees track days or autocross. For DC2 owners searching for 94-01 Integra non-Type R lowering springs, 1.75 front and 1.5 rear drop, or a DC2 sport spring upgrade, this is the established H&R option.
No. The manufacturer lists this Sport Spring as applying to non-Type R Integra models, so confirm your trim before ordering.
The manufacturer lists the OE Sport spring (part 50145-55) at an approximate 0.75 inch drop front and rear, while this 50145 set is listed at approximately 1.75 inches front and 1.5 inches rear.
Opinions vary among user forums. Some owners ran these springs on stock shocks for more than a year without failure, while others say factory dampers are calibrated for stock ride height and wear faster once lowered. Inspect your existing shocks before installation.
Owners on user forums consistently recommend a four-wheel alignment after lowering, because toe and camber shift once ride height changes.
This is a moderate-difficulty job for a home mechanic with jack stands and a spring compressor. Per user forum strut-service writeups, the spring must be compressed to relieve tension before the strut seat nut comes off, and struts are not interchangeable from side to side, so mark them during disassembly. Strut mount nuts should be tightened with the vehicle's weight on the suspension, and the strut housing tab must line up with the fork slot during reassembly. Plan on a four-wheel alignment once the car is back on the ground.
