So how does the carbon fibre wrap work anyway? Is it some self adhesive poly? How do you keep the orientation going around the bends?

Yes, don't even think about hitting the track without a front strut bar. I did once and almost rolled my car. Could have been catastrophic

AS one of the previous poster mentioned, I've had the car 2 weeks and dropped like $4000 in upgrades.... It's a build thread... the operative work being BUILD.... it's a project... Suspension will come in due time. It's lower than the stock Xi from measurements I've taken and my understanding from BMW is that the M-Sport does lower the car somewhat... I may lower 1.5" - 2" . Never going to be slammed; its a daily driver (winter included). Probably replace the suspension in the spring. As far as whether its at 370 or 340 to wheels' find me a 4 wheel dyno and i'll give it a run. otherwise, there's no way to tell for sure.... tell you one thing for sure; it's damn fast and a few Mustangs and a 300ZX found out how much quicker recently...

Do you have photos of your car with stock wheels?
Nope. I changed them within an hour of getting the car. They'll be my winters

Thats all in the wrapping.. Carbon cloth embedded in a poly resin (specifically designed for use with CF). About 4-5 coats of resin in total before clear coating (4-5 coats). Keeping the orientation is the trick and why I hand-wrapped all the parts. Alot of finessing the cloth to get it to contour to the corner or edge. Often a further edging and finessing at about the 4 hour mark (about half-way through the curing process.. But this is an entirely different discussion.... LOL

Is this stuff purely cosmetic or does it have performance benefits? Like making a flimsy part rigid?

For example, let's say I can make an automotive control arm out of cast aluminum. Alternatively, the control arm could be injection molded from a plastic then wrap it with your process, mainly to save weight. Is that even conceivable?

SAY what!!!!??

I can tell you people drive the hell out of cars on the track, and not rolling them because they don't have a strut bar!

Interior trim has lots of flex during high lateral G cornering. For this reason, BMW M/Porsche/Ferrari have been using CF extensively in interiors to enhance lateral road holding capabilities by reducing chassis flex with the use of tight dashboard trim bits to hold the car together.

I would prefer a strut bar before I track to provide even flatter response through the corners, but I drive it like I'm on the track regularly and it handles great. My reason for not tracking it this fall is simply because I don't know the car well enough to push it that hard yet. Mosport has some corners if taken wrong WILL put you in the wall; this is not the car I want to chance that with until I know it very well. I WILL be building an e30-based track car over the next couple of years as time and $$ permit... that will be my permanent track car.

I am planning to be at the cruise next weekend, so I'll have 500km to get used to the car under hard cornering and braking.

Installed the upgraded angel eyes (6K LEDs), upgraded the HID Headlights to 6K and installed a 6K HID kit for the fog lights yesterday. Unfortunately no time to take pictures last night and it's raining today.... So, I'll try to get some pictures at some point. What a PITA it was to replace the H8 bulbs not to mention that every site I visited only have installation instructions for non facelift (non-LCI) installations. significantly changed on the LCI version. the little access they provide was no where big enough for my fingers and I tore the shit out of them trying to get them installed...Installing them was more difficult than may of the big repairs I did on my last one and by far the most difficult mod I've done today.

Started doing the intercooler as well, and got the stock one off, but realised completing the job would take more time than I had yesterday, so re-installed the stock one and I will tackle that another day.

to clarify the CF discussion. CF is lighter and stronger than steel or any other metal for that matter. So for racing purposes, replacing stock metal exterior body panels with CF molded parts reduces weight significantly (stock hood = 60lbs; CF hood weighs in at around 20 lbs) and since it's stronger than the parts its replacing is an excellent choice to reduce weight and not sacrifice protection/strength.... The CF market I was selling to was the aftermarket and for cosmetic purposes only... same approach BMW and other manufacturers have with offering the CF interior as an option. People looking for aftermarket cosmetic parts aren't looking to reduce weight for the track, they are looking to enhance the look of their ride.. its that simple.

Thanks!

Hey... I'm an engineer.... I was intrigued since the wrapping is real CF cloth with a real resin, not some stickers.

Imagine if this stuff added structural rigidity with minimal weight penalty?

Sweeet ride. I've had my Black 335i for just about 6 months and all I've done to it is add the OEM Black kidney grill (totally recommend that for your ride too btw - it just makes the front end look really aggressive) and put on 18 OEM wheels !

You`re way ahead - great work.

my previous 335i pushed 420/367tq at the motor with a jb4 tune, bmw perf exhaust/intake, downpipes, and pullies on 94 octane. but just so you know, the hotter the engine, the less it performs at optimum. Great build! i think i've seen your car around Markham

Curious but since from the manufacture you start with a 50/50 car, how does saving 10-30 pds here and there affect balance? It is not like the car is made in carbon fiber and balanced 50/50.

I wonder if a 55/45 or 10% difference can even be felt in terms of balance/handling.

I am more of a straight line guy so the twists and turns are not my thing to know this.

I try to add or remove similarly from both ends/keep the balance. Too much weight in the front can cause oversteer and too much in the rear can cause understeer. My last 330Xi was perfectly balanced and was flat through the corners. I had eliminated the understeer they are prone to. When I added the subs and speakers to the rear (net 40ibs) the car began to understeer again.

Balance for cornering is crucial. Adding the front strut can help provide more down pressure on the corners reducing understeer as can camber adjustments. I used to use ground control camber kit in it and adjust on track days.

Thanks! Those are the numbers I'm aiming for. I'd like to get 450hp at the crank. Very happy with the jb4. With the xi configuration and super wide sticky tires can't get a squawk out of it as it puts power down on all 4 wheels.

For those of is old enough to remember the 80's, we'll recall how the Audi Quattros were so dominant against the field that they were banned from professional Motorsport for having an unfair advantage over the field. You put similarly modified 2 wheel and AWD models against each other on a track, the AWD will always dominate.
