60-40 drop

Is there a handling advantage to lowering 60-40 rather than just 40 mm or 60mm or is it just a look's thing?

It's a looks thing due to the E30 stance, if you lower it 40/40 then the front will look a lot higher than the rear.
60/60 is crazy as the rear wheels are under the arches and then you have clearance issues depending on the size of wheels used!

Yeah mine sit's higher at the front like you said. 40mm drop at mo. Did wonder about 60-40 but wondered how it would affect handling, for worse or better? if any different.

Depends on the kit used, on my 2.7 conversion I can tell you now it wasn't the engine performance that put a smile on my face, it was the H&R Cup Kit, the 60/40 drop made it handle great.
It would be the wheel/tyre combo that can ruin handling I found, obviously there's bushes etc to also consider.

60/40 is the best all round drop if you use decent stuff. It's good on road and not too low and it will put on a good show for the odd track day imo. Oh and it's the best looks wise too

I wondered about this too.
Standard MTEC is -15mm right? So would dropping just the front -40mm even out the stance?
Is it okay to drop just the front?

you can't go that low the wheels will rub on the back and pull the front arches out everytime you turn
royalratshit the car will look silly if you do that and handle also in a very strange fashion, plus thats very council.

i'm bored snowed off work and i don't like you. How can i help myself, you have a pop when your in the mood. I'll stop as we can't wreck another thread.
Remember you need shorter shocks if your using 60mm drops! 40mm is the limit on m-tech shocks

E30Sam - that's just ridiculous ... but there are a couple of danish guys over here with -80mm - looks crap.
Royal - in theory yes you could fit Mtech springs at the front (-20mm I think) - BUT you will end up with a very unstable car. You will still have standard "wallowing" springs at the back and a tightened up front end.
I wouldn't get in your car if it was set up that way.

No dude.
I have MTEC all round just want the front to be a tad lower to lose that E30 front gap look.
Re:

by Simon13
only the 60/40 drop will achieve this, 40/40 won't lose the gap at the front just lessen it
look at my sig of the alpenis - 60/40 and just right

You can get front top mounts that will drop the front by 10mm ... that might be worth a go if you want to drop the front a bit more.

This is my motor with a 60/40 drop.
Theres no weight in the back of the car so it sits a little higher at the back than it should. The front is slightly lighter than standard but if it was any lower it would piss me off as ive still skuffed the front a few times as you can probably see from the pic:

the ride height is pretty much perfect for me- great handling and still goes over most speed humps

Do you fellas replace all the bushes when fitting a 60/40 kit? Will a full powerflex kit do the trick?

you may as well replace the bushes with a powerflex kit if theyre old.

you can go poly if you like, i wouldn't personally.
they are cheap and stiffen up the car, but they are known the fail in a spectacular way with the control arm bushes. They will help give a bone jarring ride. Good for track but thats all i'd say
60/40 on uprated bmw bushes where you can fit them is the tits and the ride is hard but not too bad. Thats more the bilsteins i'm using though as they are very stiff.

Would I be able to run a set of 8 x 16's with a 60/40 kit? ET25, 5x100 under the standard wheelarches?
Simon, where do I get the uprated BMW bushes, BMW itself? I want a decent compromise between road/track

Those top mounts are also available in Germany.

To be honest I really like mine on the road. It's poly bushed all round and is dropped 60/40. And my wishbone bushes haven't fallen apart yet!
I don't find it too harsh, just feels nice and taught, I'd personally recommend them.
Maybe I'm just used to having my spine smashed in stiffened Minis and Mk2 Escorts!

Hmm...maybe someone should offer front wings with lower arches to match the rears

Re:

do you mean higher arches?!
you can buy all the bushes from BMW, granted they are more but they work. They all come from the M-division parts bin!

No, i mean lower arches, more in keeping with the rear arches.

Mine is dropped 60/40 with KW springs and shocks, H&R anti roll bars, strut brace and all bushes replaced (standard bushes I believe) and it handles great. Just ask Ant.

I have 60/40 handles great, the cornering control is there when you need it, just fed up with it as it my daily driver, most speed humps are fine with 2 wheeling it over, but theres some that i just can't get over without scraping the whole underneath, theres a whole town near me called Bean that i can't go to or through
I want to raise 35mm all round but as said about the front looking higher, would say 40/35 work? handling and look right?

Who does a 60/40 kit of springs and shocks?
I would like to use bilsteins prefferably? Do they do a 60/40 kit?
What are the advantages of using m3 offset bushes and will they work with a 60/40 drop?
Will be going on a tech2, first mod to be done to it!
Re:

you can go with an H&R cupkit, or you can try and source the springs on their own. This is a bit tricky as they only come with the kit and you can't buy them on their own. Or you can use KW 60/40's. Use these with inverted bilsteins either 45mm or 51mm ones work fine. The 45mm spec ones work best on track and give a harder ride as there is less travel in the shock. All these setups work very well. Although i have never used KW springs so cannot comment but i expect they will be fine
M3 offset bushes work fine also in a normal E30, the wheels may rub on full lock when parking etc depending on which wheels your running

KW suspensions complete suspension systems consist of high-quality lowering springs and specially matched sports shock absorbers, which have a shortened stroke and are adapted to suit the new conditions. The aim of the extensive raod tests is to achieve optimum interaction between the shock absorber/spring unit and to enable significant improvements in handling and road-holding. The sporty, hardmonised tuning delivers excellent road-holding and safety, without the uncompressing loss of residual comfort
