\n ULTRA \/ HIGH-STRENGTH RACING SPRINGS\n<\/h2>\n\n

Since the start of the company in 1980, involvement in top international motorsports has been part of H&R’s DNA. Countless victories in various racing classes and series are the reward of continuous development work at the highest level, innovative research and state-of-the-art production processes. By using high-strength spring steel wires, H&R racing springs reduce the “unsprung masses”, an effect that has a positive impact on the vehicle’s handling. In addition to the best corrosion protection, the elaborate production process includes many different operations which distinguish the quality of H&R race springs. A wide range of accessories such as spring plates, intermediate plates, adjusting nuts, lock nuts and many more complete the H&R motorsport program.<\/p>\n \n \"\"\n \n\n

\n Main & Helper Springs\n <\/h3>\n
\n

Main Springs:<\/strong><\/p>\n

Are made of extremely solid spring steel. This leads to a reduction of weight and more travel for a given spring rate than competitive springs made of usual spring steel. The main spring has a linear characteristic. By choosing suitable bump stops the block setting of the main spring must be avoided in use.<\/p>\n

Helper springs:<\/strong><\/p>\n

Made of a special trapezoid material which resists long lasting solid stress can also be used. They can either increase the rebound travel or the response of the spring system, depending on whether the helper springs are already closed and have more travel, or if they can still influence the rate of the chosen main spring. To harmonize the intersection of the main and helper spring there are also some progressive helper springs in the range. In addition to this, there are also many accessories available like spring plates, setting nuts, counter nuts and bump stops.<\/p>\n\n <\/div>\n <\/div>\n <\/div>\n

\n Formula 3 and Formula Student (SAE) racing springs \u2013 small but fine\n <\/h3>\n
\n
\n
\n

For the smallest formula racers H&R has developed a range of springs with 36 mm inner diameter. Here too, precise production with low tolerances forms the basis for reproducible driving behavior. The use of high-strength spring steel allows a low weight and a large spring travel in relation to the length and thus contributes to lightweight design. A range of helper springs complements the race springs offered.<\/p>\n<\/div>\n<\/div>\n

\n Group-G-Springs\n <\/h3>\n
\n

In case a coil over suspension or a main- \/ helper spring set up is not allowed in a race series, special springs with an OE spring support can be used.These springs are designed for the specific race purpose. A combination for the matching race or rallye shock absorbers concerning length and characteristics is recommended. To ease the assortment, the free length of the springs is mentioned. The shock absorbers extended length must be shortened to guarantee an prevent the springs from slack with the wheel hanging out.<\/p>\n

The springs are partly available in different spring-rates and different heights. The part numbers mentioned are for one single spring, by ordering please remember to order 2 pieces per axle.<\/p>\n

The part numbers are composed like the following, example 1:<\/p>\n

RG664VA-100<\/p>\n

=> Race Gr. G, based on spring set 29664 (BMW E30) , front spring, spring rate 100 N\/mm<\/p>\n

Unless otherwise noted the race springs are designed to a lowering of 40-50mm.<\/p>\n

Additionally there are Group G springs with original height or even higher which are especially designed for rally use with it\u00b4s fierce conditions like jumps and \/ or gravel stages.<\/p>\n

Example 2: RP701HA-110<\/p>\n

=> Race Gr. G, Rally, based on spring set 29701 (BMW E30 M3) rear spring, spring rate 110 N\/mm<\/p>\n

Individual special applications are possible on request, as far as technically possible.<\/p>\n

For enquiries please mention the car details as well as the race purpose and the requested height (original car height or lower \/ higher).<\/p>\n

Please note: The springs are delivered with a T\u00dcV approval of the matching public road spring set to make the homologation easier (in Germany: homologation following \u00a7 21 STVZO). More info \/ data of the Group G springs are not available.<\/p>\n

Group G springs do not have an own approval.<\/p>\n

It is recommended to clarify suspension changes like this BEFORE homologation, in case a homologation is needed.<\/p>\n

Please use the request sheet on page for your individual inquiry.<\/p>\n\n <\/div>\n <\/div>\n <\/div>\n

\n Monotube Race coil over kits\n <\/h3>\n
\n

H&R race coil overs are renowned in racing series worldwide. High grade monotube shock absorbers are used with application-specific high tensile springs to complete race-suspensions.<\/p>\n

The struts are upside down technology and the shock absorbers are equipped with spherical bearings whenever possible. Suspensions are built to order, so delivery time may vary and will be given on request. Custom made suspensions, based on the H&R layout, are also possible.<\/p>\n

Alternative spring combinations<\/p>\n
