Need some advice!, new to the BMW E9 but not new in the restauration of cars. I have an BMW E9 2800CS here from 1969 and want to buy some coilovers and saw this company in the Netherlands. The guys says it's plug and play, but i think that i must cut my original struts and weld them on the new coilovers.. And must i use my upper strut with bearing again? or are these already in the new coilovers with camberplate? And i don't now if the back is going to fit, because it looks like that it is a other top-mounth then the original shock, these have two bolts (but maybe it's a universal picture by the Ad?)

There is a lot of expertise in this forum, so i hope you guys can give me some information.
Thanks in advance! (sorry for my poor English)

You have a beautiful car. I love how your photo balances the headlights and the remaining daylight!

I’m very suspicious that the vendor is using a stock photograph! The upper mounts look like they might work ok, even with a camber plate, but like you say, you would be cutting and welding your strut tubes drastically.

Perhaps the vendor has a reason to be confident but I know how difficult it can be simply putting Bilsteins in these struts if, for instance, one has been replaced with one from a later car.

But please do let us know if the vendor emails you pictures of the product in a real E3 / E9 / E12 / E24!
 
this is strange.... sure a universal picture.
I have about the same setup , build and installed by Intrax.
It involves welding the front struts, welding in the camber plates and adapt/reinforce the rear towers.

That was + 5000 €..... in 2014...

IF they have anything for E9 , i suspect 4 shocks and springs for that ad price.

I send them a mail and hope to get some pictures! Thanks for your reply!

The seller is near me. I think I'am going to take a look soon, although he has to order everything too. so he probably doesn't have an example laying there. What did you have to weld for the camber plates? Do the coilovers replace the steering bearings (upper strut bearing) or do you put them back above the pillowball top mount? You suspect he sells 4 shocks and springs for that price.. i don't hope so :-) i have to order them online and the delivery time would be 3 weeks... o_O The vendor is BC-racing in the Netherlands and only sell coilovers and other ralleystuff so I am curious to see what they come up with.
 
special plates welded in to accept those camberplates
coilovers replace everything.... nothing oem anymore
Most welding /custom fab is in the rear as now the towers get all the force from shocks and springs. Oem it is only shocks.
I payed a little more than the ad price here ( German vendor) for indeed 4 springs and shocks.... seems quite normal. That was a Bilstein "kit" for my 850i.

Intrax is also Dutch.... you could inquire , they have the design of my car.....must have been 2014.
I have their "black" coating on the shock rods, against stone impacts. Must say , after 6 years rallying it , still perfect condition.

I'm also curious what you will get ......

Hey Belgiumbarry,

Thanks for your reply, I'm going to do some more work on the e9 first, i have a cloncing engine (cranckshaft bearings? so first things first! I will place the order early next year. Seems like a nice job to make everything fit.

I didn't understand how the pillowball worked, I thought it only provided the angle of the coilover, but if I understand you correctly, it also provides the rotation of the coilover. just looks like a small flimsy bearing to me. But we'll see. I also had a look at the intrax stuff. But that is certainly of a different caliber! I'll keep you informed. Thanks!

Right! Whenever you modify something, you open a can of worms. As Belgiumbarry points out, the rear shock towers on e9's are a well-known weak point. Adding the spring loads to those towers will certainly necessitate some reinforcement.

My first question for coachmen would be "why?". Are you going to be racing your coupe? Upgrading the rest of the suspension? If you are contemplating a full-on, hotrodded e9, then sure, go for it. But otherwise, why deviate from the stock spring-shock design? The folks in Munich sort of knew what they were doing.

Why this change? I want the car a few centimeters lower. Ans some part on the frontsuspension are shot. for example i need new parts such as the upper bearing. Also the mounting is bad at the front where the coilstrut is mounted to the fender. So I have to make some modifications anyway. Why not do it all right and let the OEM parts disappear. I also looked at loweringsprings and came across H&R e12. (probably easier/cheaper but i need need new upper bearings then) However, I don't know what kind of coils to put in the back... any ideas? every info is welcome! have a nice day!

I'm not sure I agree with your statement: "I have to make some modifications anyway. Why not do it all right and let the OEM parts disappear." It isn't clear why modifying the car is more "right" than just fixing it. It sounds to me like you need to make some repairs - not modifications - to the front where the coilstrut is mounted to the fender and replace some worn components. And while you're in there, you want to install shorter springs.

I'll bet that at the end of the day, your proposed coilover modification will run into more time and money than just doing the repairs and swapping in shorter springs. But hey it's your car - just be sure to make your decision with your eyes open.
