2020 MY z4 m40i. US spec for us only came with 6 port. 10.9 bolts, still had plastic oil pump.
Pump never “failed” but it wouldn’t maintain oil pressure target once it hit certain temps on track. Used 30, 40 and 50 weight oils.
If you’re serious about tracking, get rid of the titanium lug bolts. Depending on how often you remove the wheels you should also consider studs. Skip out out Motorsports Hardware and go to MSI or Bimmerworld’s kit.
contrary to what’s been said, I’ve been in white line links for the last two...
Unfortunately you’ll have to do PCA to do Charleston peak pretty much moving forward.
CCW lvms is a lot of fun! They remove turns 1-3 from the CW config and no curbs to catch you on the exit of turns though. I did a 1:44.32 my last go around. Sundays are always less crowded with SV weekends if...
You can call Mike @ carbotech to get them made. They usually ship within a week after ordering assuming the backing plates in stock. Say you’re a BMW CCA member and they’ll give you a discount.

I was on KW DDC’s until moving into MCS 1WNR. I had two sets of DDC’s because I blew two shocks and warranty replacements take 2 months.
I wish I just went with MCS from the very beginning. They’re still very road friendly but so much more capable on track. Buy once, cry once.

I had to remove the lower bracing when installing the BMS. You’ll spend more pretending you can working around rather than taking the extra 10 minutes just removing it.
lower pass side fastener is close but clears the nut in the body bracing.
I know Bailey woods uses something similar for his b48 setup on his e36 m3. I haven’t seen him at a speed ventures event in a long time so I haven’t been able to ask him about it.
if this is the direction you’re going, take my money now. I’ve been needing something in addition to my manifold...
“Hi, I’d like to add wider tires on stock wheels so I gain 0 benefits of a wider track, spend more money, and make my car handle worse. Any recs?”
do the Vorshlag plates have any caster adjustment? Their plates always looked like good quality.
I’m also curious as to how dealers choose their springs. They all seem to come up with some reason why they choose swift vs hyperco vs eibach, etc.
The rears do
In my experience they are significantly better than the standard 348mm and 374mm 4 pot brakes. With castrol SRF and g-loc r16 or r18 pads, brake fade hasn’t been an issue the last 14 track days I ran this year. They’re incredibly confidence inspiring, even after putting a shit ton...
If you’re partial to MCS, I’ve heard good things from bimmerworld and limit+1 in Chicago
Personally, I went with Racewerkz in Burbank CA. Majority of their business are race cars, but also will do street cars. Casey, the owner, has been awesome to work with and even did a free divorce...
Shoot, you’re right. There is an offset difference of approx 2.6cm. I guess the rear wheel hub is just different on the M cars.
this was a good find, but I’m sorry you had to figure it out like this
The rotors shouldn’t affect clearance as the caliper carrier bracket is the same for both non M and M series cars. Because of this, there shouldn’t be any offset difference between non M and M rotors. With that being said, I am running a riveted rotor from a non M car and NOT the pin drive style...
This is what I do also. I’m not a safety expert, but I run a Simpson Hybrid S when doing so. I’m under the impression that locking the belt removes 3 major safety functions for 3 point belts:
1) the belts ability to stretch and decelerate the body
2) the ability for the body to roll on the...
