I Just Lowered My E30 316 1986 The Springs Are 60mm, But I Have Not Changed The Shocks They Are Standard. I Feel That The Car Is Still Sitting Higher Then I Expected, Is This Because The Shocks Have Not Settled Or Do I Need To Change Shocks And If So Any Recommendations On What Ones To Get Thank You.

The Car Is Still Sitting Relatively High, About And Inch Above The Actual Tyre. Do You Know If I Need To Change The Shocks To Make It Sit Lower Or Do I Have To Wait For The Shocks To Settle ?

Please Stop Putting A Capital At The Start Of Each Words.


It makes reading very difficult. Remember E30s sit lower on the rear naturally anyway, look into E90/2 drop hats as they will lower the front an extra 10-15 mm, if you want lower youl need coilovers, but as magpie says itl chew sumps like fucking wine gums. Best thing to do is drop the back 40 front 60, and have a bit of rake, stick deep 16"s on there and itl look a treat

The shocks won't like a drop like that, probably sat on the bumpstops! You'll need shorter shocks and have you used 316 springs?

i like the arse end lower than the front,just like ky old mk11 escorts.

the way my galvaniser sits isn't as harsh though -40mm eibachs on the rear and -15mm mtech sport springs on the front .

i don't want to change an m50 sump :wink:

His is an '86 car so has a totally different rear arch profile to the one Magpie has posted so it won't look as low on the back.

Yeah, my pre-facelift sits like standard on the rear, even with a supposed 50mm drop. Front looks good though, thats meant to be about 75mm, but it's only around 50mm.

Also, M10 sumps sit relatively high. I've only knocked mine once, and they're made out of steel so they take a bashing before they go ;)

Change the shocks, so they match the springs a bit better. Overwise you end up with the shocks reacting too slowly for the stiffer lowering springs and funny handling. Changing the shocks won't lower it more though, unless it is actually sitting on the bumpstops (which I highly doubt). You can only go so far with lowering springs. You're going to have to start looking at coilovers if you want to go lower.

Half the problem with the rear is that on pre facelifts, the rear arch sits higher than on facelifts, so it looks like it's higher. You shouldn't have too much trouble with the front. Also, tyre profile makes a different. A 15" wheel with 205/50's fills the arch a lot better than a 16 with 215/40. Rides nicer too :)

Mine looks pretty crap when parked, especially downhill, but when its driving it levels out alright.

Indeed. Good little engines considering how old they are. Very easy to tune as well.

I've gone for the stretched tyre look as i have deep dished wheels lol :/.. I have 16's with 205/45/r16's on the rear and on the front i have 195/45/r16.. I think i am gonna change the shocks and maybe cut the springs :). What do you think ?

Let's nip this in the bud:

Suspension is a critical aspect of any car, and for the rear end twitchy nature of the E30 correct suspension is critical if you want to keep your wheels on the asphalt and your head facing in the right direction.

While BMW set up the car for the right balance of comfort and performance, people adjust their suspension depending on their specific needs, whether its increased comfort or increased performance. But either way it means buying the correct parts for the situation.

To that end, each component is critical. Each shock and spring has to support 300kg of weight, a quarter of the car, on a steady even path while the wheels are bouncing up and down to the road conditions. Lowering springs reduce the height of the suspension, and therefore the amount that the wheel can move up and down, but to compensate they use thicker steel so that they can still carry the weight of the car.

Butchering a normal spring means that you're removing that much strength from the suspension; when the wheel hits a bump it will be launched upwards, effectively punching the car from underneath, and you've removed the car's ability to absorb that shock just because you want to be cool in front of your mates.

This will ultimately mean that a raised manhole or a nasty pothole will send your car fishtailing. If we're lucky, you'll crash into a tree and only kill yourself, but knowing Sod's Law you'll take out a family of three on your way, killing them and saving yourself. Just because you wanted some stance, some lows, the right profile to make your car look sick, innit.

It's only a 316, and it's only a manky old Beemer, but it's still a 1.2 tonne killing machine and it demands a certain degree of respect. Taking an angle grinder to the springs is just plain stupid.
