H&R Sport Springs - 1989–1990 Porsche 911/964 C2 & C4 (2WD/AWD)
H&R's Sport Springs are the classic lowering upgrade for the air-cooled 964, available across the Carrera 2 and Carrera 4 in Coupe, Targa and Cabriolet form.
H&R’s best-selling lowering spring. It closes the fender gap, lowers the center of gravity, and cuts body roll while keeping the car comfortable enough to drive every day. The progressive spring rate is what keeps this from riding like a track spring — it works with your factory dampers, not against them.
Important Compatibility Information
BMP also stocks the matched 24mm front / 26mm rear 964 sway bar kit.
Why Choose H&R Sport Springs
H&R crafts every spring in this line from a special (hf) 54SiCr6 spring steel and shot-peens it, a process H&R rates for more than double the service life of an untreated spring. Every spring is 100% tested before it leaves H&R’s ISO9001-certified production facility in Germany.

Frequently Asked Questions
Will this affect my ride quality?
It firms up, but the progressive spring rate is designed to keep the ride comfortable for daily driving — this is H&R’s daily-driver lowering spring, not a track spring.
Do I need new shocks to run this spring?
No. H&R designs it to work with your factory dampers, and BMP does not require a shock upgrade to install it.
Do I need an alignment after installing this?
Yes. We recommend a four-wheel alignment after installation, our standard advice on any spring or sway bar job in this family.
