View Full Version : E36 belly?

I used to drive an MKV GTI. I'm set on getting an E36. I was wondering what the belly side of those cars are like, what do you E36 guys smack off the ground the most, pan/subframe/beams etc. I feel like subframes on MKV's hang down pretty far, you can get one on the ground but the body will still be about an inch or more off the ground.

Frame rails.

im not ridiculously low, but i scrape floor mostly, theres not a lot of chassis rail, but that scrapes too. pan sits fair high, dont recall any marks on it last time i was under the car.

edit:

couple pics of the bottom of an e36

awesome. stoked to get what i find mad low. im sure its not the same feeling as smacking subframe/oilpan.anyone ever "drop" or crack anything from hitting something too hard? im sure its not the same feeling as smacking subframe/oilpan.

Front sway bar and frame rails are the first things to hit on an e36. Easiest to drive slammed car I've ever driven

this, my old e30 four banger scarped the oil pan with broken springs, those pans hang so damn low.
the e36 so freaking easy to drive lowered. its only the frame rails that scrap.

yeah, dude, you're going to love it. my wife's mkv is pretty low (23" ftg), but my e36 is a lot lower with just over an inch frame rail to ground. i'd say (and she probably agrees) that the e36 is just as easy to drive even though it's lower. i have been scraping my frame rails a LOT though, but it doesn't affect driveability.

Most 6cyl E36s have the fuel filter sitting next to the frame rails (I think it's got to do with the year), so relocating it might be a good idea if you want to go really slammed.

But apart from that, easy going.

My mkv was a daily, static at 22.1". Im so incredibly stoked to slam an e36.

it just kills me when i scrape the frame rails on my E36. it's just an invitation to corrosion.
anybody coat the rails with POR15 or similar?

10-17-2011, 05:47 PM
You realize that if you coat it, it will just scrape off...

reportedly POR15 is chip and scratch resistant. i'll believe it when i see it though.

plus i'd rather have to keep coating it than having the frame rails rust out in 5 years.

lol. huge difference between scratch resistant and the weight of the car dragging on the pavement at any given time. the forces aren't the same.

while we're on the subject of low e36s, are you guys running fender liners? i'm rubbing mine quite a bit and considering removing them.

SeanDub

No liners, though I wish I had kept them in to keep rocks and dirt out of my door jams

I understand that, I am a mechanical engineer. i do not need a lecture in physics. The point is that the product could potentially be more useful than a rubberized spray on coating, which would definitely come off, if it were scraped (as evidenced by the factory undercoating...)

Furthermore, while surface rust could potentially be "scraped" off, it doesn't negate the fact the bare metal is subject to moisture and dirt, which will accelerate corrosion.

I don't get how nobody has this concern.

Dr.AK
10-18-2011, 02:52 PM
I run the fender liners, but I'm not as low as some (about 4cm / 1.5inch at the frame rails). I don't have any rubbing, so no issues there... if I were to go lower and would encounter rubbing, I'd still keep them, I'd just trim the top most portion so the wheel's got enough space to move. But the rear and front parts would stay on for sure. It just looks ugly when you can look THROUGH the wheel well to the bumper for example, imho.

Then don't lower your car.

LOL obviously you're not getting my point Sean.

For me, it's about doing things right. some people are OK with rubbing or baseball bat rolled fenders or fucked up frame rails. I'm not one of them though and it seems peculiar that in a community like this, nobody has been concerned with bare metal on frame rails.

SeanDub
10-18-2011, 03:18 PM
You're grinding metal off, you really think a coating will withstand what the metal can't?

If its that big of a problem, don't drop it.

i guess we aren't on the same page. read the posts by the OP. he wants to get "mad low." the picture that comes to mind is skrapez aka Josh's e36. that car was "mad low." any coating that you sprayed on, would be scraped off and would expose the metal regardless. you dont need a ME degree to understand you are sanding the product right off when that low.

if you are rarely scraping any of the chassis, then you would be looking in the right direction.

yeah sucks i got a 4.0 gpa for my masters and designed and built an SAE baja car. If you want to get into a pissing contest, message me dude.

i merely expressed a concern and was curious if anybody had any experience with a product since we're all "car guys" and I didn't think i was the only one that would cringe at the thought of rusted frame rails.

back to OP yes, if it's "mad low" i agree, no coating will stay on any frame rails. Regardless of that, corrosion is still going to occur (which is my point). my question was in reference to moderately low and utilizing a coating.

IDK my E36 is what i would call moderately low, i would call Mike's E36 moderately low too. Josh's car is very low. IMO it's like lowered (BF.c); Moderately low (Mike's E36); Very low (Josh).

in driving my car i can avoid anything that would potentially scrape the rails EXCEPT getting into my work driveway. granted the car isn't my daily but i was just really concerned about having bare metal. That's all LOL.

10-19-2011, 07:55 AM
if you are that concerned about rust, build some sort of skid plate that will sit against the frame rails. so only that part will scrape / rust, then replace it when its worn down.
there really is no other option, except if you cut them out. but that will leave the fuel / break lines unprotected and would easily be damaged.

if you dont wanna scrape your car on the floor dont slam it.

oh you wanna slam it? get an x brace it will protect your pan even though its no where near danger

what about my frame rails? dealwithit.gif there no way to avoid it if you are low.

skid plates only will reduce clearance not worth it, so either get 18's or dont slam it because your rails hitting the ground is inevitable




i also want to point out that you have to notably really low to constantly hit them andscraping them once in a while is ok, they will look like dr ak's above which is fixable if you care that much.

you would die if you saw mine or other really low e36 rails. ill post a pic when i can

something else was a factor, the pan sits over the rails and subframe.

there had to be something out of the ordinary as in not just a bump or dip

i'm not sure if this is in reference to me, but regardless: i was asking if anyone had experience with a product that was different than conventional spray-on rubberized coatings, which only one person actually answered. you're dynamite drop-in had nothing to do with my question, was out-of-scope, and shit yeah i got offended.

i can't grasp the idea that people who "love" cars so much don't see rust on the frame rails as a concern. let alone the fact that we're talking about "frame rails" that really aren't frame rails since the car is unibody. whether it's a 5k BMW or a 50K BMW i'd still treat it the same way. i'm just a pussy with cars.

and like the numerous other posts; if you're that low that you're scraping, either be anal and keep protecting the steel or just man up and go ballin'

I suggest the you man up option.

It's not like the floor is gonna fall out like in fast and the furious, all you'll get is a little surface rust which is easily repaired should you want to restore it or just decide you don't wanna bang it anymore.

For what it's worth I wouldnt do it to a e46m or e39m but fuck it it's the most produced BMW and probably one of the most produced European cars. So have fun, banger up and fix her or throw her out.....or just don't slam it.
