Product Details

H&R part number 51657-88 Race Springs are engineered for drivers who demand uncompromising handling performance on the street or track. Manufactured at H&R's ISO 9001 certified facility in Germany, these race springs are built to exacting standards using a proprietary 54SiCr6 spring steel alloy rated at 290,000 psi tensile strength, delivering exceptional resilience and long-term durability.

H&R Race Springs provide an aggressive lowered stance combined with race-ready handling characteristics. The stiffer spring rates tighten body roll, sharpen steering response, and lower the vehicle's center of gravity — translating to dramatically improved cornering performance and a purposeful, aggressive appearance.

Key Features:

  • Manufactured from proprietary 54SiCr6 spring steel for superior tensile strength and resilience
  • Produced at H&R's ISO 9001 certified engineering and manufacturing facility in Germany
  • Lowers vehicle an average of 1.75 to 2.5 inches for a lowered, race-ready stance
  • Designed for race-level handling — responsive, tight cornering with reduced body roll
  • Direct OEM replacement fitment — no cutting or modification required
  • Compatible with H&R Triple C Camber Adjustment Bolts to correct excess negative camber after installation

For optimal tire wear and handling performance after installation, H&R recommends pairing these springs with a camber adjusting device such as H&R Triple C Camber Adjustment Bolts to dial in proper alignment geometry.

Great web page!

Half the price of local parts store

Satisfied with the whole experience. Fast speedy service. No issues at all.

Wonderful e3 spark plugs direct fit for my 84 porsche 944. Will never use a lesser plug! Thank you autoplicity for wonderful prices and fast shipping.

Found good sale price for LED headlight bulbs on google shopping and it was very easy to get shipping estimate info and complete order. Very good experience.

purchased chrome tailpipe extension - very nice product

real pleased with the transaction

Great Price fast shipping, I can't complain.

Great transaction. The bike rack was about $90 less than a local retailer, and shipping was faster than promised. I wish all internet retailers were this reliable and useful.

It was easy to order and the truck bed extender we bought was the lowest price we could find! However, the shipping charge was higher than what was posted on the comparison sight. Nevertheless, it still came in under the next highest price from a different vendor.

Order arrived quickly and was exactly as described. Great prices and service!

Very fast shipping and price is rite

I was searching for brake rotors on the Internet for over 3 hours tring to find the best prices-- Autoplicity beat everyone hands down! The best deals out there. Quick response and my order shipped within one business day! Bravo. <br><br>Their website could be improved by auto selecting make/model combinations. I had to double check the part numbers for the pads..they matched the rear pads with the front rotors. I only caught this due to the fact that the pads were extremely cheap..too cheap. The low price was for the rear set as front pads usually at more expensive due to their larger size.

Fast service, great prices, highly recomended retailer.
