Which coilovers gives the most drop?

Hi guys,

Ive been looking at coilovers for the 135 but seems like the max drop on the KW is only 2inches. Are there any other brand coilovers that can drop the 135 more than 2 inches?

Found some other brands like H&R, Bilstein and Eibac. most of them also only drops the car 2 inches.

Im looking for coilovers with 3-4 inches drop.


Thanks for your help.

i'm not a huge slammed guy (live in Northeast Ohio, can't afford to be) but the only way your going that low is on bags. Someone else will have to varify but no coils i've seen/heard of go that low and still provide longevity of the suspension; that's compressing the strut quite a ways

since you're obviously not out for performance, just bag it. adapt an airrunner system or something

Bc racing's can go ridiculous low... Absolutely undriveably low!

Just Tucking tyre, and there's probably 2 inches to go. Easily tuck 18's, i'll fully lower them sometime and take a few pics

I cannot see any reason to drop the car over 1 inch in my opinion. Once you start tucking the wheels into the fenders, you make the car look awful.

Which bc coilover youve got on the car? I tried looking for bc coils but they said they dont make them for the 1 series. Who supplied your bc? Are u able to give me their details?

Also whats the maximum drop on the bc? 2,3,4 inches?

Just to be clear, you do know that 4 inches equals 10 cm, right? If you dropped a 135i by 4 inches, it would be absolutely undriveable in Sydney, where there's no such thing as a flat road...

over m-sport suspension, the fronts need to be about 1.5" lower reasonably to be flush.. rears only need like half an inch maybe

BC BR's, the lowest ones.. ER's are more like $1700 or so

justjap have them for around $1300 or so? they are the same as the E9x ones, so just look for the E9x non-m

i'm not sure on the max drop, 2+ inches for sure, 3?

i'll let you know when i do it

this is a good point.. even in brisbane... go lower than 10cm minimum clearance and you'd need to wind up damper stiffness.. that would SUCK

4 inches would leave <10cm clearance for sure

....which is precisely why I said for him to go air suspension.

seriously, if you're dropping that low, you're doing it for looks. do it right and run air/hydro so you can lift it for shitty streets and dump it for hard parking and shows.

4"+ drop is absolutely idiotic on coilovers. you're just making life hard on yourself. If you don't want to spend the money to do it right, sell the 1, buy something more air-friendly that leaves more room in your budget, and do it right.

Google answer 1: http://www.thehoffmangroup.com/c/air.../2008_Bmw_135i
Google answer 2: http://www.ecstuning.com/BMW-E82-135...pose/Air_Ride/

didn't search any more, but you get the idea. both these look like about what you'll get on any market for our cars. BMW is the ultimate performance machine, not many buy for sitting on the ground. hoffman group looks complete where ECS you'd have to piece it together yourself.

Hahaha. Have you owned a car that low? Stock ground clearance on my car was 5.5". With 3" drop, you would scrape on absolutely everything. Every speed bump up and down, every driveway in and out, every rise or dip in the road. Please report back on how it goes.

Anything adjustable you will be to go as low as you want, like Standard Suspension R3, Got those on my E36 and I love it, can't wait for the ones on the 128i to need replacement.

This is the guy that you have to wait behind as the carefully negotiate each speed bump in the parking lot.

Congrats on the coilovers.

Do you mean to say that e9x non M coilovers from BC use the same spring rates & dampers as e82/e87 BC coilovers ?!? I need to knwo this soon, Thanks!!


Did you get SWIFT springs too?

E90/E92 will fit E82 in terms of springs/shocks/coils.

Yes - bc only lists e9x coilovers, they have 7kg/mm and 11kg/mm, you can convert it to lb/in. There i no special offering for e8x

No, they're not a thing over here, standard springs. Plus i bought them used for supe cheap
