    Idk if this is true or not, but I do know that if you are going to modify the trans, the dct is better. you can get a good set of upgraded clutches from ssp for half of what it would cost to fully build a level ten 6at transmission. and even then, the built 6at is not yet proven. :-(

    Ya I never skimp on suspension, I'm thinking KWs, sways, BMW/Brembo big brakes in the front and maybe forgestars or HRE vintage wheels and fat michelin PSS tires Click here to enlarge

    the 6AT has Alpina software, the dct there's no upgraded software, with dct the slippage starts at 470 lb-ft even lower, the 6AT with Alpina flash can handle up to 520-550 lb-ft.

    if u r plan to upgrade the stock turbos with big single, forget the dct

    I disagree. It's a better choice than the auto.

    if it was the DCT of the f10 M5 u should disagree, but it's a 335i DCT, weak very weak

    You know it's only basic internal differences between the two and programming as they are the same physical size, right? They both have the exact same capability.

    The 7DCI600 in the M3 is the same basic unit. The M5/M6 use the 7DCI700.

    Why are you trying to tell me what's what?

    Haha.... So on a more positive note.. HRE Vintage 501s in matte black, what do you guys think? Would they "work" on a Z4?

    Nice project. There's a local guy that has RB's on his z4. I wasn't there but when he put it on the dyno it started slipping. Also seen 6AT slip as well. I think it's only a matter of time with either trans.

    Huh, cool.

    I'm thinking about a spec clutch for the build, anything else I would have to do to the manual trans? Also, what do you guys think of spec clutches or have a better suggestion? Thanks.

    I agree with this. thing is, a built level 10 trans is like 4-5 grand...whereas an upgraded clutches pack from ssp for the dct is 2500. lol.

    Wouldn't a M Coupe be better for this project? Proven M bits. I believe there is a kit for 600+whp if you're up for it. Last I looked, which was couple weeks ago, there were multiple M Coupe < 32k miles.

    Thanks for the suggestion but, bluntly put I really dislike the styling of the M Coupe (Opposite of how I love the styling of the Z4). And I would prefer a more recent car because (I don't know how well this belief is founded) that a more recent car will be significantly more reliable than an older one. I don't know how the chassis compare, stock to stock the M Coupe is probably better, but in terms of which chassis has more potential I am leaning towards the new one.

    If I may add though, the M Coupe has the benefit off all suspension bushings being based on conventional tires, whereas the Z4 uses RFT and softer bushings to accommodate. I wish death to RFT technology, it is the worst invention mankind has come up with!!!

    That alone is enough reason for me to only buy M cars from now on, since they only use conventional tires. Doing a full susp overhaul and replacing every link and bushing on both my 335's is not something I wish to do everytime I get a BMW.

    Enough of my rant, the Z4 is a beautiful car though

    I too hate RFT, they so often completely ruin cars suspension and handling. I really don't understand why there was so much push for them, I guess people thought a stiffer sidewall was better but at what cost? And also most race cars actually use a fair bit of sidewall because they found that a little flex was actually helpful. But I digress, if you don't mind me asking, what/who's bushings did you go with? I am looking into powerflex but don't really know where else. Thank you, and I totally see what you mean now.

    Ya it's the good looking ones that always get you, haha.
