H&R sport springs on KONI FSD's

**FrankA6** · 12-21-2008 02:54 PM

will it work? i have Koni FSD's with Eibach sport springs, and i want to go a bit lower, will the H&R sport springs work on it? or do you guys think its not such a great idea??? let me know!

Yes

I would check with Koni USA - I have only seen recommendations for sport springs or Eibachs pro-kit as a match for the FSD.

I still think you have it backwards -- change the shocks to sport (Bilstein -- Koni yellow a bit harsher?), keep the Eibachs. But if you're determined to get lower, H&R sport springs are lower than pro kit. At least 1/2 inch. (Remember, I was asking you about your pro-kits when I was researching this, deciding on springs, shocks.) If you think your FSD shocks are a little on soft side, do you really want to get lower?

yeah, just a little bit.

that's what I'm running right now. The only real issue I have is getting into the parking deck at work. If I go straight onto the down ramp, something under the car scrapes just the tiniest bit going over the edge. I have to hit the ramp at a slight angle.

That's what I use right now, and I am very satisfied

KONI does not approve of the combination as it kinda negates the purpose of the FSD, which reuiqre more travel to work the way there were meant to. They'll also won't work wiht you if yuo end up having issues. I personally think you'll bottom out/rub in some places and bounce more.... but really it is doable... just with a price.

yeah like $300 for springs and thats it.

Frank - I thought it was the "bounce" you wanted to lessen, no?

Brice -- helluva game last night. I think they'll meet again.

**FrankA6** · 12-22-2008 01:08 PM

the car has to much bounce, and its not low enough , but im not sure yet what im going with.

**Gigi** · 12-23-2008 10:49 AM

FSD's will give you that slow bounce but stiffen in harder driving in turns, which is why people get them, while the yellows will be lower and more aggressive therefore harsher in daily driving, over bad pavement.... it is a tradeoff, can't have it all :) Your best bet may be to spend the $$$ and get PSS(, adjust height and dampening til yuo find the right setting. But it is so much $$$ for a car not tracked.
I think, your car look real nice as is and your ride is still good...

Wofman, - yeah... poeple are so frustrated... they were hoping :)

would you mind posting a LINK to this, because several tuners are selling FSD/Spring combination.

In addition, could you post to where " They'll also won't work wiht you if yuo end up having issues. I"??

Also - is this your personal expereince "I personally think you'll bottom out/rub in some places and bounce more."? or is this just conjecture?

I did not say or mean that there will not sell FSD/Spring combos.... I HAVE on my car a FSD/Spring COmbo that came in one box... I was just responding to Frank's questions specific to H&R Springs with FSD's. When I bought mine, the Eibach springs were the only one they sold with the FSD's.
So the links I would post wopuld be the same you can pull yourself by searching retailers/distributors' sites (I.e.: Tirerack, GMP...)

post what? I found out by working with my local shop and talking to a Koni person. Just call their number or email them to inquire...
But if they did not test or approve of H&R springs with their FSD shocks, it is just very likely that they will not work with you and may void warranty if you have a problem on yuor car with that combination. Also like I said, the FSD is built to achieve a specific goal and it needs enough travel to do its job. The FSD is much closer to a stock shock in its behavior than to the Koni Yellow frmo my experience with all 3. And stock shocks, evensport, don't work well with aftermarket springs epecially the low and mroe aggressive ones like the H&R Vs a Eibach.

Experience with three different setups (Stock Shock/H&R - Koni Yellow/H&R - Koni FSD/Eibach) and the stock sport setup, as well as common sense.... soft shock with more aggressive/lower spring on a 4,000lbs car...
The FSD is very soft compared to other products like Yellows...
I experienced that bounce/bottoming out with my H&R springs on my stock shocks (SPORT OEM suspension) and I quickly added shocks...
Are you looking to change suspension?
