I wanna drop my 325i sport beast down as much as possible without having it scrape every speed bump i go over!! I like the arch coming over the tyre look!!. im running 17" alpina reps. Now i understand theres loads of threads on this but i can't find what im looking for!..Im thinking of the 40mm drop but i don't know if thats going to give me the arch low look! i know if i drop 60mm it's going to look the dogs goolies but will it scrape everything!! Also will i need to change everything for the drop!? or will it work out cheaper if i just brought coilovers?!..Thanks :cool:

60mm is fine as long as you have a route that avoids solid all the way accross the road speed humps.

Mine is mtech suspension with aftermarket 60mm drop and rolled arches. I've never clouted anything *touches wood* underneath and I frequently bump up a kerb when I park up to collect the kids from school. Obviously, I take speedbumps very slowly..

Man up and get some 60's.... they look the dogs boll*cks

It would be better to get a full kit, one thing I have noticed with mine since lowering it 60/40 is the rear camber, it's not kind to the rear tyres wearing the inner edges quite quickly.

If you don't want this to happen but still want it dropped then if you look in the group buy section 'Danthe' is selling some adjuster plates that need welding to the rear beam, add some adjustment bolts (detailed in the thread) and you can return the rear suspension to factory camber/toe settings.

At least running 17's you'll have less issue with ground clearance...

17's are fine on a 60mm drop without rubbing IF you have the right offset wheels. Also note that when dropping to 60mm unless you use shortened shocks it will fail it's MOT as the springs will become loose when the car is raised.

The ground clearance will be the same be it 14/15/16/17's if you are using the correct profile tyre, 205/55/15 is the norm on an E30. Check tyre sizes using this calculator HERE

:lol: BMW E30's offset is ET24, your new wheels should have and et number stamped/embosed. The offset is a measurement from where the wheel meets the hub to the outside of the rim IIRC.

If you can stretch to coilovers you could just get a full 60mm kit, decent coilovers for the E30 start at around the £500 + or a full 60mm kit would be around £200-450.

Hazd31 I'm not suprised you were scrapping everywhere with 185/60/14's :eek:

The jamex ones don't appear to be proper coilovers, you get a kit to modify your front struts and an adjustable rear spring platform that would sit were the original spring would sit.

Have a look around THIS site to get an idea as to what is out there, they stock all the decent brands. This place is really good value.

If that's the answer, pm me, I'll sort you discount fella ;)



This thread got complicated though!

If you were sensible and running 15's you could do whatever you want - I'm dropped over 70mm and yes, I'm mega, mega low, but I'd still happily run lower and just roll my arches and go even slower over speed bumps.
Just a case of growing balls, manning up and fitting the right wheels! :D

60 is too low IMO. Sure it looks good, but you loose the handling (weight shifting from side to side round corners can make it "snap" out on you easily).

40 is the practical drop. Easier, cheaper, less things to take into consideration, better handling over 60mm drop (when not fussing about camber, toe in/out etc).

If you just want springs, 40mm drop. If you really want 60mm, make sure you get a proper kit.

Anything else, coilovers win. Adjustable coilovers will give you the exact drop you need/can get away with. Also,

Dan's adjustable camber plates will straighten up the wheels to avoid bad wear/grip issues or allow you to get that perfect 'under arch' look.

Image

If you can see, the top of the rear wheels is more inwards towards the car than the bottom. Thats 'negative?' camber. This will cause the inside of the wheels to wear much quicker than stock camber. When you drop a car, thats what happens to the wheels.

Uni is killing the project.
