Bottoming out h&r race koni struts xdrive

Dom_J · 03-17-2013, 06:47 PM

Anyone know of any good aftermarket bump stops? The factory dust covers didnt fit, of course.

Any ideas fellas? I haven't adjusted them to full firm yet as they are on full soft till.

Just installed, test drive, and I think they are hitting.

Help me out fellas

*note* I haven't installed the rear shocks yet. Still h&r race on stock struts...idk if they'd help but worth mentioning.

So....

I've sourced Koni's progressive rate style bump stops.

Part Number: 7034950000

This is turning into a painful and expensive lesson learned at this point haha. All in the name of low.

SP lowering perches (RWD E90)
Front Strut Mounts (RWD E90)
H&R Race springs (RWD E90)
Koni Sports (AWD E90)

So I'm a good $700-$800...I've achieved the ideal drop! .....I don't think there is another E90 AWD sitting lower than me right now, especially up front....

Driveability.....work in progress.

Right now:

-Roughly 2-3" of shock travel
-Very Tame around corners/on straights
-NO BOUNCE what-so-ever
-I need to keep the lowering perches from hitting the spring seat on the konis.

Besides which I would have just saved and went with the h&r street coils, I don't have many options from here.

-Throw away money/time spent, attempt to sell what I can, save for coils = oneight headlight conversion money...gone

-Try these progressive rate bump stops....pretty much ride on them daily(through winter) $100

-Remove the lowering perches to possible alleviate some shock travel along with the bump stops

-Source custom built shock (extremely difficult)

-The question is can the koni's ride this low? I believe people have even used these to convert to coil over set-ups.

Now that I think about it, the SP perches put the strut DEEPER in the "cups" so to speak so I do have the travel, the issue is the perch is hitting the spring seat on compression...maybe the bump stops will alleviate this.

Idk...money spent, tired, confused, moral is buy the good stuff first, AWD is always a pain in the ass anyway. Any input or suggestions would be nice. Thanks.

First! I found my tie sway bar link was disconnected, they didnt bother to mention that...second, it looks like the spring seat is hitting the bottom of the lowering perch due to the perch sitting so "low" into the spring due to bringing down the strut mount.

Looks like due to the lowering perches

Ive been here. i was using koni yellows with H&R sport (they dont make race for xi's) with the sp lowering perch and the ("i") tophats to work with the perchs. got fustrated at that point. sold everything and got kw v1's been happy ever since.

idrift4wd · 03-18-2013, 05:25 PM

get H&R sport springs, Endlink just disconnected like that? that cannot be good.

You got a good link for them at a good price? I'm weighing out the h&r street coils right now, contemplating hitting the buy button. Do the V1s get pretty low for us AWD guys?

I'm sure they ride pretty comfortable.

Exactly....lucky I took a look back there.

I'm wondering how bad it would really be to ride on the bump stops lol they're not really supporting the vehicle or if I should attempt a coil over conversion w/them possibly.

I may just attempt the conversion...already have the shocks and information needed to do so. Hell, do it like the old days.

Very interesting, I'd completely the lowering perch.

I'm thinking coil over sleeves at a 2" diameter.

I don't know what diameter I should get for springs just yet:

ID 60mm (2.25") 65mm (2.5") 70mm (2.75")

I bought mine used for 800 with 5k miles on them. im on 19's and they get pretty low, definitely no wheel gap in the front. I do like the way they ride. I was also considering the H&R's but i spoke to my uncle who had the h&R's then bilsteins then kw on his m3 and said the kw's were by far the best. so i went with the v1's

Dom_J · 03-19-2013, 06:17 PM

I wish I could find a deal like that! I guess I'll just have to keep my eyes peeled! lol

Do you mind posting pics of your current set-up?

I think I am going to go w/the coil-over conversion and custom coil-springs. I'm in too deep at this point. Might as well, go the extra step.

-If all goes well, I should be able to match a 6" linear spring at about a rate of 400 lbs.

-With about 800 lbs of weight at each corner, that'll drop the car down roughly 2" with the weight of the vehicle applied.

-The Swift spring at 6"/400 lbs rate has about 3.5" of usable stroke so I'm in the ideal window at this point. Koni rep just told me these things can handle up to 650 on a full track set-up.

-Taking into account that I will be chopping the Koni progressive rate bump stops to about 1.25" I now should be able to sit the vehicle down with roughly 2.25-2.5" of shock travel, which should be plenty.

With the usable rod length of the koni strut(for the AWD) extending about 7" I should barely squeak by with the height of the spring sitting right at 4-5" weighed down.

It can all work out in theory, the awd's have been converted a few times already, Henry is definitely a magician. Only thing is, he's never attempted the set-up with a 6" spring, only 7" this should be interesting.

OP,

If you decide to sell what you have now, you may take this kit into consideration --> http://www.tcklineracing.com/webdocs...Details690.cfm

Front struts are shortened, so you don't lose compression travel, and car will sit fairly low for you.

PM me if you're interested......

I'm upset I came across this kit so late!

I spoke with you guys on the phone earlier

& my fiance made the order on the top hats.

I'm pretty much at a stand still, I guess I will gather pieces and try them out. The spring rates I used were 448 linear 6" tall. Shortening the strut is what Koni mentioned on the phone earlier as well, its a smart process. I will have to hit reset on the piggy bank and save up for your kit and sell the same up I'm piecing together for someone looking for good performance and a moderate drop.

The only other way I can think of getting strut travel back is a pretty slim strut mount at this point. I have both set's of top hats, AWD & RWD E90.

Highly interested in something like that blue one but I think its for an e46.

Dom_J · 03-20-2013, 09:36 PM

If there is anyone w/an AWD sitting this low around? Please post pics.

This is my "fail set-up" but I've achieved the perfect stance I was after! >.< 1" of shock travel...no bueno.

- H&R Race Springs
- RWD Strut Mounts
- SP Lowering Perches
- Stock Shocks (terrible idea)

Was this your setup? The kW coil over housing with koni yellow stuffed in the middle? I have a set of kW v2 for a rwd with blown shocks and brand new koni yellows, trying to figure out what to do.

Koni x-drive struts converted to Swift doesn't offer enough compression travel and may bottom out. You may be able to get away with it if you run higher than usually rates and trim the bump stop. Shorten body is the way to go.

Right I get that but if I run the KW shock bodies and remove the Koni inserts from my yellows and put them in the Kw bodies using everything kw other than the inserts, would that work?

I don't think they are interchangeable. Worth a look into though.

HP- Yeah I've been researching for a while now and it seems a lot of the v2's use Koni inserts. The older kw systems used to use a straight up koni yellow for their rear shocks. I am receiving the KW said I bought today, so I will let you know how it goes.

To the OP, Dom J- I have the same set up of Koni yellows up front and H and R race springs for a rear wheel drive vehicle upfront and it is one of the worst rides I have ever had. I'm guessing it's just that the H and R race springs are very harsh and going that low we are definitely bottomed out. I don't know about you but I feel every bump and feel like the bottom is just going to drop out from under my car. People that are in my car, usually ask if something is wrong lol.

KW uses Koni inserts, that is very interesting. Perhaps due to issues they had with the dampers in the past.

Due to the limited travel on the front suspension you need a short body strut. The use or race springs further takes the travel away. Swift Spec-R is a good choice on the xi according to some of my customers. It is a higher linear rate spring that doesn't slam the car.

A custom short body Koni strut is available, but you must run it in a true coilover setup using linear rate springs.
