Touring suspension options?

[P3RH4PS]

I've done a bit of research already so I'm planning on the sls delete, but I can't find from there a relatively cheap kit to buy.

I may use bavauto's sls delete kit, but I don't want stock ride height. So I'm looking for lowering springs and shocks. I only want to go about an inch lower, nothing crazy and I'll do any other diy sls delete if anyone has any advice on that. Please help!

If you're going SLS delete then a sedan rear spring on same application shock will work. If you remove all SLS bits, then all you would really need is a non-SLS p/s pump. If you keep all the plumbing and pump in place then a simple bypass at the rear of the vehicle is all that's needed. I can't wait to do mine. Just haven't made the time to get it up in the air and start removing the stuff.

I stock bilsteins and B&G lowering springs for the e34 touring. The B&G will bring you down about 1.5" evenly front to back.

That's what I'm running on mine; couldn't be happier.



Perfect stance, IMO. Not low to the point of scraping everywhere you go, but no real fender gap either.

Do you have any idea how the B&G lowering springs will work on a touring with E38 16" x 8" basketweaves with 10mm spacer? The spacer is needed to clear the spring perch up front with these wheels. I am using M Tech springs right now and they do not drop the car much. I would like to close the gap but not if my tires are going to rub. I currently have Konis up front but also have a set of Bilstein HD's for the touring.

I'm thinking of going that route. I have to sls delete first.
How much for the set? (Bils and B&G)

Shouldn't affect it. I'm running B&G's / Bilsteins with E39 style 5's 17X8's and have run E39 18X8's M Parallels in the past with no rubbing issues.

Style 5's:

I'm planning on SLS delete and then running some Koni SA's with shorter front inserts (more shock travel) and some sleeved coilover adapters so I can run higher spring rates. I plan to start out 450f 550r. Plan is to be 1-2.0 lower and have decent ride and no scraping. Style 5's with 245/40's

I will be yanking my Billie HD's and installing some sports very soon. I love my B&G/Billie setup but I'm going more for handling now.

I had the same set up and a 3mm spacer should be enough to clear the strut with the e38 wheels.

You need to ditch the billie's and get Koni. And higher rate springs than B&G. I run 550f 630r on the E36m3 i drive daily and it rides better than stock.

Based on the weight of the E34 touring to get really good handling spring rates of 700-800 rear and 600-700 front will work and probably nto ride bad. The E39 M5 guys run 800f 1000r on the street and track...

Weight has the enemy.

[Inv3ctiv3]

I have always had Koni's on my E36's and always liked them but I just want a good kit that will lower the car and still ride well. This is my hauler not a fun race car so whats good and decently priced?

[attack eagle]

why the insistence on SLS delete?
It rides great, very firm and planted. leave it in place and you'll never have to worry about a 1000 lbs or more of weight driving the rear toe to 0 and the accompanying dangerously wandering rear in gusty conditions.

[Inv3ctiv3]

Don't you have to delete it to mount any sort of aftermarket suspension?

[attack eagle]

why would you WANT an aftermarket rear suspension when there is nothing wrong with the one there now?


If the only lack/desire is a lower ride height, you can simply reset the ride height mechanically via reindexing the hydraulic ride height valve. no need for new springs and struts and upper mounts and SLS deletes etc etc. You have nothing to lose by trying it before spending a bunch of money after all.

I have run Koni's on my E36M3's and E30's for years. My touring is going to get temporary suspension, then later I plan to do Koni's. Unless the temporary suspenssion turns out better than expected.

I did some research it seems Votgland springs with Boge/Saches or KYB GR2's is a good daily driving set up with lowering aporx 45mm front and 15-20mm lower rear. Spring set is around 200-250, TUV certified.

In an effort to have the front shocks not bottom out I am going to use a shorter shock insert in front like the E36, and E30, guys do sometimes.

I have a set of springs from a 535 we had at one time with Jamex suspension on it. I may stick the rear springs on with shocks and then just cut the front springs down to get the nose of the car slightly lower. Probably play with ride height. Sometime after all the gremlins are worked out and its painted I'll do coilovers and Koni's.

I don't normally load 1000 pounds of crap in my car.. I have a truck for that. I MIGHT load 200 pounds of stuff wich wont' effect the ride/handling much.

I'm like you I want it to ride nice and look good... I have a track/toy car aready

Yes. I posted a bypass thread.. its really easy...

[Inv3ctiv3]

Yea I saw that, great write up.

Would these fit? Bilsteins with 22mm nut?

I want new shocks for a little bit lower ride height and my shocks are totally blown 200k on the originals for all I know.

[GGray]

Should if its E34 stuff. They all use the same srut up front as far as I know. Out back you will have to buy the upper shock mount and a new bump stops. The fronts have the stops in the shock itself since the Billys are inverted desgin shocks.

You may have to play around with ride height with shims but shoudln't be bad. Normally you shim under the upper perch or lower depending on how much shiim you need. Old school method to corner balance cars for stock class racing

400 is pretty cheap!
