Looking for a functional splitter

Does anyone make a functional splitter besides BW? Looking for one that extends back to the front wheel center line. Something like :


Rules: "Splitters are free providing they do not exceed maximum body width, do not extend rearwards past the front axle centerline, do not extend more than 3" past the farthest part of the front spoiler or bumper as viewed from above, and follow the general outline of the spoiler. Installed devices must be consistent with the spirit of the original design of the car such as those presented by aftermarket sources. Dive plates are allowed."

I plan on making my own but I'm just looking for ideas specific to the e46.

Did you check with Steve J on bimmerforums? He has a few contacts.

BW used to source theirs from Secart, which I believe is now defunct.

Greg,

I'm not sure if you've ever seen the BW spliter in person, but the build quality is incredible. This is, dare I say it, a one time purchase-put it on the car and forget about "offs" kind of product.

The World Challenge specs it was built for are identical to the ones you have for club racing.

PM me if you want more info...

+1...i used the old style (world challenge) splitter on my E36 for 3 years and am now running their new splitter (built to take advantage of bmw prepared class rules)

not exactly...the rear of the WCTC splitter needs to be trimmed to be prepared legal (at least this is the case with the e36 piece) and a splitter built to the limits of prepared rules will not be legal for WCTC...the new E36 splitter sticks out quite a bit further than the WC splitters...

I'm sure it is a very nice piece but I'm on a very tight budget at the moment. I beleive I can get 75% of the return for 10% of the cost of the BW splitter, and I'm fine with that. I have bigger issues I need to deal with than having the best aero setup.

One thing I'm curious about is whether or not to make the front height adjustable, then I can decide on how to mount the front.

i wouldnt worry about making it height adjustable, keep it simple....

for mounting, do not attach it to the bumper cover. make some beefy (angle iron?) mounts that attach to the bumper/frame rails. this way when you rip the splitter off, the bumper stays...oh, and you might as well make a spare or at least keep the template...

I can make you a splitter that looks like that but you would have to figure out how to mount it to the airdamn + bumper. Let me know. charles@velocitymotoring.com

Heh, cutting it out is the easy part, mounting it will be the hard part .

Hi Dave,

I was referencing the E46 piece, but you are right it needs to be trimmed at the back. I think James has them all made oversized at the back to facilitate perfect fitment. (From different bumper deformities)

How far forward from the leading edge of the bumper are you allowed to run the splitter for an E36?

This is a pretty good example of what I'm thinking of.

EDIT-There are actually 2 examples in the above link, both look pretty decent.

Hmm.. deng didn't know BW charge 1300 for one.

You know how I end up destroying my hartge lip?

I end up making one like OP posted, extend all the way back to the oil pan. With the front tip looking like the Audi R8 super car. Ill post pics when I'm done. Didn't cost much to make. Strong and light btw.


squred at the ends, notched out in the middle.

1300 includes the splitter, riser, and mounts...if you see/hold/use one, you'll understand why they charge what they do...like i mentioned earlier, i used their older model for 3 years (a ton of track time) on my race car without issue...i've seen countless lower quality splitters torn off of race cars...

looks are subjective...it looks like a large splitter made for race cars...if it's for a race/track car, looks aren't really important...if it's for a street car, well, it probably won't be on the car long enough to matter anyway...

Ask barry to make you a copy of ours....it doesn't cost us much in materials, and it doesn't take long to whip up spares.
