1+ on removing the EDC, car feels way better with coil overs.

look for F80 control arms and find a sway bar the car handles way better

I do about 4 events a season and enjoy the 335 very much, Im running 245 / 265 setup for tires.


DVC I need find out more on coding the Elsd and other nannies out haven't tried that yet

Here's the thread on coding for the F chassis: <link>

I agree on the F80 control arms in addition to the sway bars.... The F80 front LCAs have a nice spherical bearing that is an improvement over the F30 bushing; the F80 tension struts are a must to maintain proper front wheel geometry when the F80 LCAs are installed, but the F80 TSs have the same mushy bushing as the F30 version, so I went with Dinan mono balls in mine. Also, I swapped 4 of the 5 rear control arms (no after market option for the roll over strut) with Megan Racing arms with heim joints, and then put delrin bushings and spherical bearings in the OE roll over strut. Not to mention solid rear subframe bushings. No rubber anywhere in my suspension at this point, so the car feels pretty dialed. And yet it's still more comfortable on the street than my friend's stock BRZ.

When I used to track my c5 z06, the abs and stability control would kick in and ruin my lap times. There was no way around it unless I rewired the car. Less tech feels a lot better unless you are porsche or mclaren and you build a 1 million dollar hypercar.

Modern BMW ABS is so good...A lot of serious 911 builds swap in the Teves mk60 units from e46 M3s for a significant upgrade (excluding the GT cars, which use sophisticated Bosch units).

TC/DSC has come as long way too. Back in the early e46 days, it was unusable even in spirited street driving...but now Sport+ with a mechanical LSD allows enough slip angle to really rotate the car in turns without ever intervening. And if you code out the eLSD, then you can run in DSC off with zero TC/stability nannies.

Sounds good to me. Before I install anything, I gotta have the dealer repair some vibration coming from the rear. All my stage 2 parts are waiting to be installed. Anything above 70mph includes a horrible vibration from the rear end.

So the cost offset going from a new F80 to a used 335i makes up for the upgraded rotors and mods on the F30?

The C5 is a much stiffer chassis surprisingly. St1 and St2 class is full of really fast c5 z06's. For some reason the C6 chassis is too soft and feels too heavy around corners. Plus the vavletrain issues in the LS7 doesn't help. 🤔

C5 Z06's are no joke, my buddy has one with heads/cams/exhaust and it's a monster. For the money, they're a much more capable track toy than an F30 even with some mods. I just could not live with that interior, way too much shiny plastic.

I had a 4th gen CAMARO with the ls1 that I had the heads ported and custom cam and ls6 I take was good for 420 rwhp. I never knew the c6 chassis was a problem. Lg Motorsports beat all their c5 times in a c6.

Ya lg had sequential transmissions in the c6's. I'm referring to normal track guys that attend hpde's or time attacks, nasa, scca. The c5's are typically faster and lighter.
