lmao I think it’ll look weird with a carbon strut brace right above a carbon engine cover. I just feel like it’ll look overkill for me and less of a “clean look”. I feel like I’d either run the carbon strut without the engine cover on or the engine cover on without the strut brace

just a question for you guys, would a sway bar do the same thing as a strut bar ? both help with body roll / stabilizing correct ? Someone offered to sell H&R front and rear sway bars for $500, so I’m wondering if I should skip the strut and just buy those. And yes I am aware the rear sway bar is a pain to install lol

In short: Sway bars reduce body roll due to cornering. Strut braces prevent the strut towers from moving which otherwise would cause the suspension geometry to move out of proper alignment thereby negatively affecting handling. So they don't do the same things. |

So sway bars are for more cornering control and strut bars are for more traction control and stability in straight line speed ?

Yes sway bars improve cornering control, but strut braces don't improve handling over what the potential of the car is capable of, it only prevents handling from being lost due to suspension components shifting out of place. Braces will work in all kinds of driving conditions, so long as those driving conditions place a load on the strut towers and causes them to move and flex, in this case I don't think you'd feel anything for straight line driving because those loads are unlikely to cause much flexing to the strut towers. Even if straight line driving did flex the strut towers, I doubt a reduction in strut tower flexing will yield any gains that can be felt, because driving in a straight line really doesn't allow you to feel any improvements in suspension geometry. In essence if you are only street driving or more concerned about straight line performance, pretty much all of these mods won't return much of a gain.

Think of sway bars as adding more spring rate. A thicker bar will prevent “roll” through higher spring tension at the cost of weight and less independence of the other wheel on that axle.

Track use and auto x will see the biggest impact. You'll feel a difference with hard street driving too (unless all you do is straight line stuff, where small losses in suspension geometry won't really be felt, maybe you'll feel small bits of hunting in the wheel but likely nothing)- but it won't be as appreciated as on track, because you'll never hit the same limits on the street. Remember M cars come with massive bracing increases from the factory over non M cars, so you won't feel the same massive improvement in steering feel over stock as you would with a non M car. So the reviews that alot of YouTubers say they feel with a strut brace likely will not be observed until pushing the car hard. Last edited by F87source; 12-29-2022 at 02:20 PM.. |

I decided on getting :
- NRW F87 M2 carbon fiber corner braces - Slon Workshop F87 M2 carbon fiber front upper tie bar - Turner Motorsports carbon fiber N55 engine cover I wanted an OEM + looking but with lots of carbon fiber ! I orginally wasn’t planning on get these but F87source convinced me to get the corner braces. As well Matt, M2_ghost, gave me a really nice deal on the NRW corner braces and the Slon Motorsport front upper tie bar, which I appreciate a lot. The corner braces and front upper tie bar should add more reduce weight and increase the strength of the body, creating less body movement. Lastly, to tie everything in, I decided to purchase the Turner Motorsport carbon fiber engine cover to match all the carbon and to expose my BMS port injection intake manifold ! I’m doing all this in preparation for Bimmer Invasion, I can’t wait for the car to be complete |

“The build out is 64oz of Grand Master Twill High Density and the reinforcement core is Aerospace grade foam insert in the axial Y plane. Stronger than 6061 Aluminum of the same thickness while being lighter and has a 3 stage urethane finish for a lifetime of gloss and beauty” “Weight: 200 grams per side. Approximately 80% weight reduction from OEM. Each brace is reinforced internally with Lanter Soric XF core materials, which are used in Aerospace applications for the F21 Raptor Jet” They seem very good quality ! |

Imo marketing descriptions shouldn't be the sole decider if a product is good or better vs. another. It's the testing data and engineering specs that counts. For eg. Oil, LM has very agressive marketing and sponsorships, and they have uv dye gimmicks and yet the cheaper oils like PPE out performs it by leaps and bounds. My questions regarding these braces are: 1) what is the weave pattern and twill of the carbon used? Because grand master twill just implies large carbon weaves, it is commonly 12k but iirc it doesn't have to be. 2) it's good they have a foam insert to improve rigidity, because the brace is so thin. But are there actual testing data on these things? 3) it's good aero space grade material is being used, and not really cheap parts. Overall the brace seems to be good, but I'm skeptical it is as strong and rigid as the TMS braces or RKP braces because it's so light. This means very little material is used, and thus it is really hard to believe it can be as strong as the other braces where alot more material is used. An analogy is like letter paper vs pizza box cardboard. Cardboard is alot stronger than paper, but if you have enough paper like a phone book, then it's apparent that enough material can make up for strength but at the cost of weight, and this is an analogy assuming the other item is made of weaker material. If the other item was made of equally strong material or even stronger material then it wouldn't even be a contest. |
