Default :: ECS Tuning :: 924S, 944, and 968 H&R Suspension Components





H&R suspension components are synonymous with quality. Since the inception of H&R in the late 1970s, they have been making some of the highest quality suspension components available.

With a need for an improved suspension in the automotive aftermarket, H&R essentially created the modern-day coilover that we are all used to. Not only concentrated on “stance,” H&R considered high quality materials and ride comfort extremely important.

Now that looks interesting. Was just considering options.

What are the included spring rates or can I specify? Looks like you recommend pulling the T-bars. What does the lower mount look like for the rear? It says 'fully adjustable' - what is adjustable?

H&R does not publish spring rates because there is no industry standard of measurement, so comparisons across brands don't hold much meaning. H&R will however, build custom race springs at nearly any spring rate you desire.

As for the lower mount, it's just like the stock lower shock mount. You can see it in the product photos. "Completely adjustable" refers only to ride height with the threaded shock bodies. Valving is non-adjustable.

Really? No accurate way of measuring spring rates? Surely it is simply force applied vs deflection. What's so complicated about that? Every other manufacturer seems to have figured it out....

It's not that there's no accurate way to measure spring rates, it's just that there are several ways to measure, and no industry standard. Other suspension components that are installed affect the working spring rate, so it can vary from vehicle to vehicle. Here's H&R's article on it: http://www.hrsprings.com/technical/spring-rate-101.

H&R don't publish spring rates for their kits. However I can tell you that the 944 RSS kit spring rates are 80N/mm front (400lb/in) and 150N/mm rear (850lb/in). Works well!

Actually you can see the free length and spring rate written on the springs. For example, the rears are 120-150 = 120mm free length x 150N/mm.

That's just weird that it is written on the springs but not disclosed on the kit info. I must say though, that's a really rear biased setup.

Sure, but it is hard to make an informed decision on a particular setup without spring rate info. That link talks about progressive rates, not linear.

You can't work out wheel rate unless you know the spring rate to start with.

Hi Eric,
H&R are entitled to protect their IP. A full kit is more than the sum of its parts! Anyone considering this kit will benefit from H&R's R&D/setup expertise. Probably best not to try and second-guess them, so the specs are almost irrelevant from that perspective.

On paper it's a rear-biased setup; however the devil is in the details...

Cheers,
Mike
