Contemplating opening up the side crease/vent

It seems to be a pretty simple project the hard part is where should the opening stop? The guys that laid the vinyl in the crease tapered it almost to the ends. I feel the opening should only be vertical along the flat surface and the taper should stay closed (its only there to allow for the difference in depth of the panel). I found and attached pics to illustrate what I mean.

Some people expressed concern about the strength of the panel. By leaving the horizontal portions intact and the portions I marked with a black line in the attached pic I think strength or lack of strength will not be an issue.

It would be interesting to get a similar cf piece like the gtr and just lay it down over top. Then, put black vinyl in the holes.

Was reported earlier that it was initially the purpose of the ///M division to leave these side vents effectively open. However, development apparently struggled with getting the alignment/rigidity right with opened vents. As time for development was tight (and additional crash tests likely would be required, I assume), the plan was shelved. Missed chance, but time was of the essence. Would have been nice though. Anyway, good luck with your project.

"Was at M studio this week as part of my ED and got to talk for to a lead engineer for quite a while; He clarified that these front fender areas that now suggest the vents, originally where meant to have real functional vents. They'd be even bigger then the ~2cm they are now. (Thus cutting them open in the shape they are now would apparently not provide much aerodynamic benefit ie release significant wheel well air pressure). However they couldn't get the fender sheet stamping molds accurate enough within the allotted time/budget. Particularly the two fenders sides exactly mirroring each other in shape proved too hard to achieve with functional vents. Pity, but I do respect that they either do it right or not at all."

The front side panels are not part of the car's basic structure, ie you're not likely to run into strength issues. Originally this was the intention of the M design team yet they could not get the press molds symmetrical enough (left side vs right side). Other nice examples:

+1. The only design detail that I found missing, sadly, was this when they launched the production photos of 1M. This plus a good looking CSL style trunk, not exaggerated in size, would be awesome. They are much much more important than any lips or spoilers imo.

If it comes out well you will have major e-cred.
I'm curious if opening this up will allow hot air to escape the engine bay without more work to the inside of the fender. If its functional I'm probably on board with doing it myself, but you first!

Maybe someone like Slek can manufacture a clip-on CF piece/mini grill for the new cutout opening

Im trying to find things to distract me from doing this. Eventually I will get around to it but Ill gladly move it down the list as I get other ideas

Ill keep you posted, I am interested, I just need to make sure its going to look how I am picturing it in my mind. I may get a spare fender just to try some things out.

As far as under hood heat, it seems like the engine bay is closed off from the fender, I cant be sure since I havent looked closely.

I thought about that but would people be interested in that? Even if the piece existed I dont see many people taking a plasma cutter or nibbler to their fender.

FYI T, yesterday I spent the day cleaning out carbon buildup on a you know what. What a chore, wow

If there is solid interest on the vent fascia, I would think Slek (or someone else) would take the challenge to develop one. One issue is making sure it is functional, and without downsides (e.g. pebbles coming out of the fender damaging the paint on the doors, not sure how it is on cars with a real one, maybe there is mesh on the inside?)

PS: Ouch, good job A-, you must be hurting from it. When it comes time for mine (and sadly it won't be the first time , I'll pay for your ticket cross-country to come help me, ha ha!) BTW, just cranked her up after a nearly 2 month absence (was out of state for a while), so visceral rewarding when her internals are clean, and such a different animal than the 1///M that you can't help but love both to death.

Seems like the wheel well is closed off so the pebbles and what not cant be thrown up through an opening in the fender. Not positive since I havent taken a hard look at it yet. I do plan on doing a screen/mesh to finish the opening and not have just a gaping hole.

Something similar to my rear diffuser on my 135 (dunno if you ever saw that).... http://www.1addicts.com/forums/showthread.php?t=214705

The mesh looks good on the 135i diffuser, probably can be done on the vertical slats of the rear bumper, IIRC the plastic black trim just pops out.

Indeed, you will not be able to release engine bay pressure through the side vents without cutting through the load bearing parts of the chassis. On the front, by cutting the wheel well liners you probably will be able to channel air trapped in the wheel well.

Thats very interesting, I just dont know that it works on a european car and in this day and age. It would be much easier to do though.

+1. Structural integrity might be compromised, but if you were to place a CF insert like the GT-R, then the structural issues might resolved. Although, I don't believe engine bay heat would escape from that unless some engine bay modifications were done as well. You might be better off just using some CF wraps to accent the area.

Im not completely opening a slit. I will leave the horizontal pieces where I drew that black line. The side marker actually will cover that and it will look like a full slit exists. I think most of the strength though would be lost by removal at the top and bottom where the crease tapers. I dont plan on opening it up to a point like the vinyl inserts outline.
