Anyone notice new F80 Specific HR springs (and two options)?

They now have sport and super sport listed on the site:


http://www.hrsprings.com/application...ts/4/1686/2015
Sport Spring Front = 1.3 Rear =.80
Super Sport Spring Front = 1.6 Rear = 1.0


This is much different from the M4 springs (the sport is):

Sport Spring Front = 1.3 Rear =1.2
Super Sport Spring Front = 1.6 Rear = 1.0



Looks like this will fix the rear being too low on the M3 versus M4.

Good find. Glad I didn't install m4 spring.

Why would anyone run a regular f80 spring on an m4?

How could / would they have the same spring rate? I promise you that the m3 and 335 do not have the same spring rates stock as the chassis stiffness, design and dampers are completely different.

H and r just throwing some random ass spring rates at your car. I have no confidence that they have done any research into the spring rates for the m3/4.

Whatever floats your boat I guess. I just can't believe someone would install that on their car.

for me personally the HnR springs work fine. my daily drive consist of 5 miles to work and 5 miles home with avg speed of 45mph. on the weekend I drive to the golf course which is basically the same. I avg about 6-8k miles a year on my cars and never track.

I will say I spoke with Tom@EAS yesterday and they tracked their M4 hard all day at button willow with a pro driver and the springs held up great with no issues.

I think if your just daily driving HnR springs are fine. if you are looking for something better etc.. then yes hold out and get the coils when they come out which Im sure is very soon.

I agree with you. These springs came out relatively right after the release of the car. I'd be waiting on Swifts as i've never been a fan of H&R to begin with.

You do realize that the F80 is ONLY the M3, right? F30 is the regular 3 series.

Spring rates are trivial to measure. Shock dynos take a couple of hours. The cars have been out plenty long enough for springs, since the shape of the spring was already known and the same as the F30.

forgive me for the typo, I meant to compare regular 3/4 series with the m3/4.

there are numerous people here running 3/4 series springs on the m3/4.

that makes no sense to me personally, as I explained in my prior post.

not to mention the fact that springs only is a poor choice for performance and ride comfort, but for those who aren't as concerned about those aspects, it can be an appropriate choice. to each their own.

Will the M4 springs work well with my Adaptive suspension?

Hm, not sure why you're posting this on a thread announcing the F80 specific springs, then.

But, again, springs aren't that hard. Are they ideal? Likely not, but having ridden in and driven a car with the springs, there isn't much compromise. I've done springs on cars and hated the effects, but the M4 shocks seem to be up to the task of damping the H&Rs just fine. Thanks BMW!

I'm not sure why it was hyped on this board that the H&R springs sold would work for either the M4 or M3. The shop I'm working with had called H&R and they specifically said the M4 springs were not meant for the M3.

I agree...it was frustrating to get some misinformation from shops. Didn't make sense but they stick to their guns.

It makes sense that there is a specific F80 M3 solution from H&R now. All the 'early' adopters of the M4 or 435i springs for the M3 are probably starting to flood eBay now. By the time I get my car (late Oct) I hope there are also a few more options on the market.

for what its worth, im pretty sure the E9x M coupe and sedan used the same springs, so the m3/m4 using the same springs wouldnt be out of the question.

That way they can be the first to lower their M3/4 on the block!

The difference in rates are a given. The M3/4 rates are likely higher. In the E9x chassis the rates are 10% higher in the front and 20% higher in the rear.

It does seem early for H&R to come to market with sport springs when the M3/4 just barely released. It will be interesting to compare the OE vs H&R rates.

yes it would. if I ever mod the suspension, I personally will wait for the real products like ohlins RT etc that yall focus on offering.

I would also be curious to see the difference between the H and R 4 series and m3/4 spring rates.

Interesting - the H&R Super Sports are shared between both cars.

28802-1 / lowers 1.6" up front and 1" in the rear

The Super Sports are universal for the F80 and F82.

Only the Sports are different springs for the F80/F82
