billly sport vs. HD?

[Powling]

Where can you even find Bili sports anymore?
I literally just pulled the trigger on some Koni sports since I couldn't find any Bili's that were on back order for eternity...

I almost bought them from a few different suppliers. I had a hard time finding the Koni's I needed, so but I found them from Shox.com

I think she's still hot, but I'm REALLY, REALLY old. Check with me in 2018.

Looking through this thread for a piece of info and found this.

Checking in - do you still think she's hot?

i have HD in the front with ebay coilovers. bounce like a M*****F*****!!need sport very soon. btw i been riding like that for almost 2 month now and they havent blown..lol..

This guy is an idiot, bounce equals blown.


If you replace your springs and your ride gets really bouncy your shocks are blown. If you have new HD's, sell them to someone who isn't going low.

damnit. all this arguing is confusing me... I am running bilstien HD'z on my cabrio right now on stock springs.

If i get H&R cabrio specific spring which only drop about an 1.4" in the front and .75" in the rear, would running them with my HD'z be detrimental or not????
please someone advise

[HarryPotter]

ah thats good then.

actually i think i discovered it was the sway bar bushings. easy fix, i bought an m3/ix sway BAM

[HarryPotter]

mkcman sounds like the rear shock mount. And if you wanna hear some decent shit about kyb's talk to stereo installer.

[mkcman17]

I guess I had better check on these..I know my rears are mismatched HD/sport and I consistently hear a solid dunk sound when hitting potholes...but I feel like its more my bushings than anything else.. is it still important of I'm only on HR sports all around?

this sucks.

is it really a dire need to have bisltein sports for lowering springs?
my application is simply a daily driven car, careful driver,
and occasionally some spirited drive up the canyons, which i rarely get to do nowadays.
anyway the springs lower 60mm front and 35mm on the rear,

are the really sports my only option?
does anyone actually have experience of KYB blowin up on them?

400 is just a big chunk of money.
i think a lot can easily agree..

Interesting information, and I believe it.

They still feel different though, period.

I have thought about it since your first post, and all I can think that could explain is:


1) your old struts were worse than you thought.

2) your old struts were the p30 (small body) special BMW units that used a special gland nut compared to p36 which is your new BilSport 0335

3) your old struts were not e30 sport (maybe another BMW)

4) your new struts are revalved and you dont know it

4) you are nuts


Now, just so you do not think you are barkin up the wrong tree, a 30mm Bilstein, with the -exact-same-valving as a 36mm Bilstein will behave differently because of the volume of oil available. The valving is the same, it shows up the same on a shock dyno, BUT when it gets warm it will feel different.

id agree that this is a good idea. wouldnt go any lower than a inch though on the hds. why not the m3 rears though?

same springs in the rear, iirc.

maybe a small difference in rate, but height is too close to count. Plus, I have an 89i with late rear fenders (lower), it looks lowered in the back as is!

[Hellabad]

and thus the spread of misinformation starts. great job hellabad.

might want to clarify that there is a reason you run sports with a higher drop race spring. before all the kiddies run out and buy twin tubes because you told them there is no difference between sports and any other bilstein.

None of the e30 Bilsteins are twin tube, which is what WE are discussing.

i refuse to believe that the sports and hds are identical in performance. proof of this here:

Hmmmm. When i initially installed my H&R race springs on the bilstein HDs i had on my car, it bounced like crazy. I assumed the bump stop placement was different on the sports as the bouncing went away as soon as i installed the sports. Also would the longer tube change the bias of gas on either side of the valve? I've always felt it is a little easier to push down the last inch of compression then the first inch.[/I]

I have a shock dyno and an armload of e30 Bilstein struts, damping numbers from Bilstein engineers, and you have a "QUOTE" button on an internet message board and a sarcastic demeanor.

I am trying to tell a guy that it is ok to use HD on his car to save money.
