Hey all, new to the forum, BMWs and the UK.  2 weeks ago I bought a 1995 520i and have a few questions about it.  The rear suspension is sagging and I would like to replace the springs/shocks/struts (whatever they are called).  I am not sure where to start as far as buying parts, finding a garage to fit them (if I decide against DIY) etc.  I also don't know what would be best to get. 

 I imagine genuine BMW would be too costly, but I don't know enough about aftermarket BMW suppliers.  I don't want anything radically different, I am not a spirited driver, and I don't want to lower the car into the weeds, but if the stock ride can be improved upon then I would consider that.  

From my online searches I have seen "Bavarian Auto" springs highly recommended, but shipping from the USA and import duty would probably be quite high.  Are there any locally available suspension components that are the match or exceed the Bav auto?.  I checked Eurocarparts and they list "Ventura" springs for a very reasonable price.  Does anyone know if these are worthwhile?, also what shocks would be recommended.  Euro list many different ones which doesn't help as I have no idea how they perform.

Thanks.

Hi,

When you say that the rear suspension is sagging what do you mean exactly ? Does it feel as if the shocks have worn out ? Or could it be that someone has already fitted some "sports" springs

The rear of the car sits lower than the front.  It would look good if the front was equally as low but it isn't.  The car was fitted with a tow bar (which I have since removed) when I bought it so the cause of the saggy bum is most likely due to towing than the fitment of lowering springs.  I have been under the car for a look around and the rear springs/shocks look to be in the same condition as everything else under there.  Basically, nothing to suggest anything had been replaced. 

 The shocks do not feel worn as the car does not bounce over bumps etc, but to be honest I have never been in an E34 before buying this one so who knows.  What I may consider acceptable shock absorption might feel quite different to someone more knowledgeable about these cars.

The rear of the E34 always sits much lower than the front, it must be a design "feature" Even the front of my M5 looks too high compared to the back.

If your car has done a lot of towing the rear suspension will be knackered. If you buy some genuine BMW shocks for both the front and the rear you will transform the car. You are probably looking at about £60 per shock and a new set of springs will be about £200. It's probably no more than four hours work for a garage. If you don't want a sport set up that will make the car quite hard, a genuine BMW setup will give the best ride. I would give andy at Motormec a call who can supply you with some part pricing options on 01502 500590

And another option, if you can find a good mechanic, they can "repair" your suspension(springs cant be ofcourse). Yes,in my country you can repair them, I did so and I am very happy with it. It costs just 80 euro for 4 shocks. When your country is poor, people are starting to be more creative,right?

Thanks for all the suggestions.  Original BMW ride would be ideal but at those prices I will probably lean towards something aftermarket.  I don't necessarily *want* to lower the car, but if lowered sport springs are significantly cheaper than BMW originals then I can live with a lower, stiffer car.

Any recommendations on where to find good aftermarket parts?.  I have visited the Motormec site, but like many other sites (Euro, GSF etc) I can't tell what would be best to get.  Maybe I will try a new post asking for opinions on the various aftermarket brands I have seen advertized.

I had a set of Boge Lowering springs fitted to my 525 last week and they have improved the look and handling of the car no end They were around £65+vat from GSF.

e34m5,

Excuse my ignorance but to lower the car is it just the lowering springs that are required? is GSF - German and swedish??

Also, is this something thats easily DIY or a garage job?

Thanks


Posted By: e34m5
Date Posted: 13-November-2003 at 16:35
It really depends on what sort of condition your shocks are in, mine had recently been replaced so it was just a case of swapping the springs over. My local friendly mechanic did the job for me and charged me 3 hours labour.

Yes GSF is German, Swedish and French

If that price was for a set of 4, I would be very interested in that option.  I would sooner trust the Boge name than the Ventura set  Euro is advertising for similar money.

The price for a full set i.e. 4 Boge Lowering Springs is £65.00+vat from GSF. Part number is B99410 for E34 518-525 1988-1995.


Hope that helps

Yes that does help, thanks.  Do you have any idea how much it lowers the car?, the cars in your sig look a bit lower than I would like.  My car looks that way with 4 adults and a baby seat in it.  I can't imagine what it would look like with that payload after lowering springs.

The M5 Suspension is standard i.e. EDC Shocks and standard m5 springs and the ride is rather firm (or sporty) after having the Boge springs fitted to the 525 the ride is a bit firmer but still very comfortable and there is still plenty of suspension travel. What you really need is an M5 as it has self levelling suspension.

i dont wanna sound like a cheap skate but if its only the ride height ur worried about then the very cheapest option is buy a set of coil spring asistors which simply slide around your coils to stop them from compressing as much . they were designed to aid in towing caravans but they will be perfect for you , if your thinking that they will fall out then dont worry because when the car` is off the jack the springs  compress and hold the assistors  in tightly .  they only cost about £14  and take 5 minits to fit .
   if you cant find any , get back to me cos ive got two sets in my garage  (i had to use them in my last stereo demo car cos of the weight , they raised it up by at least one and a half inches , and the thing weighd nearly 3 tonn )

I have heard about those before and have been thinking about it, but wasn't sure if they would be a good option for this car.  The car rides fine as it is and I wouldn't want to mess up the handling for the sake of appearance.  £14 sounds high if you are talking about the same things I am.  The ones I have seen were nothing more than hard rubber blocks that wedged inbetween the coils, and went for the equivalent of £3-4 when I saw them in the US.

these arent blocks ! they wind round the coil and are made of heavy duty rubber , and things arent as cheap in blighty as they are in the u,s.

  and if you want to raise the height of the car then you are gna effect the handling  no matter how you do it ! a lower car will allways handle better than a high one !!

they have good points and bad points the same as everything

 Good points are they will raise the car up when empty , stop it from sagging as much when loaded and of course they are cheap !

  Bad points are  they arent permanent,  they will stiffen the ride when loaded up because it will shorten the amount of movement available in the spring ( not terrible tho )

 if you were closer to me i would have let you try one of my sets . but theres a couple of hundred miles between us .

Thanks for the offer, they aren't too expensive so I don't mind buying them even if I wind up not liking them.  I like that they aren't permanent that way I can remove if I ever sell.  It will probably take another drive with a full passenger load in the car to make me take the plunge and buy them.

you can find the spring assistors at demon-tweeks.co.uk

Miles, do the Boge springs leave your 525i higher or lower than the M5? My 535i currently sits about 25mm lower than the M5 in your pic(!) and I'm quite keen to lift it up a bit - just moved to a house with an unsurfaced drive and I can't get it up there!

I guess I want a full Sachs/Boge kit, but can't find one - can anyone help?

Is your rolling radius the same as mine? I've got 235/45/17s on, and looking at the pic you've got more clearance from front tyre to arch (you can't even get a finger in the gap on my car), yet when I calculate the clearance from your pic you seem to have less from hub to arch. Maybe I got my sums wrong...

Looks a very tidy car btw. My 535i's spent too much time at the seaside - got one or two nibbles round the edges.

Oh, and I checked and the heated mirrors are standard, or at least not mentioned as an option.

I am using 235 40 18 Tyres which give an overall diameter of 645mm, a 235 45 17 Tyre gives an overall diameter of 643mm so i think we can say the rolling radius is practically the same.

I think my car has been very well looked after by its 2 previous owners it has full BMWSH and i have the original invoice for £30,500 !

I'll have to check to see why the heated mirrors don't work i guess i need some new mirror glass.


Thanks

Is your car lower than this M5 that i looked at ? It has the Hartge Suspension Kit fitted. The ride was VERY firm.

Looks about the same I'd say. I must admit the handling has been impressive, especially on the limit, the low centre of gravity really disguises the mass. However, three inches of ground clearance really isn't fun, and the springs and especially shocks are now totally buggered anyway.

So, I've ordered the Sachs/Boge springs and dampers from GSF. Given that the nsf shock is now bone dry and the wheel thumps up and down demonically over every bump, I think I'll be happy with them!

Another thing - the back end of your 525 looks about the same as the Hartge M5's (and mine). The M5 looks better than the standard bum-down stance, IMO.

Miles,

I think it looks spot on. Those wheels look great. You need a bit more clearance on the front of a car than the back anyway. Looking at the photos if the front was as low as the back you wouldn't be able to turn the wheels.

I have an E34 525i the same colour as yours, but mines an early one, 1988.

Whilst I was helping my mate rub it down to respray it we found that the bumpers and sills were body coloured (the bottom bits of the bumpers), and then painted black, must just be how bm do it.

So I have left them silver, sills stone chipped finish of course, but still silver.

I notice on your car the rubber trim along the bottom of the doors, and the matching bits on the front wing and rear wheel arch are also silver, mine of course are black...I think your looks better as mine now has two black lines.

Did you buy these ? or as its a sport is that how it comes ?

As far as i know it came like this from the factory as it is a Sport, it has the same bodykit+interior as the M5

I think the sport sills are convex as well as keyed, whereas the se sills are concave. The chin spoilers are different too. INterestingly ascotgrun, your sills look like sport ones but the chin spoiler looks se! Prob you're right and it is a late-model thing.
