Same thought. We need to get that car setup so I can have some fun with it. Hate to have something I spent $100k on over the years sitting in the corner of the office lol.
At least your car is in the warehouse, mines been sitting collecting dust outside the shop :(

I can have it done in a couple of hours at most if we have all those parts in!
We can test my wheels too since my car is here lol

Stoked to see this come out as it's likely my next upgrade, not only as a complete kit so we dont have to piece together and grind things fine but also since you guys focused on weight reduction along with offering multiple options- all things perfect for someone like me looking to hit the strip with all that I can.

Are the weld 15x10s the ONLY wheels you tested/confirmed fitment on? I'm thinking of going 10.5 wide in the back if I can, but not entirely certain at this point. Itd just be nice to know I can go 10.5 or larger in back w/o modification if I want.

Ordered with promo code and drop shipped directly to the shop to install along with my pedal box. @[email protected] now design a front brake kit ideal for using with skinnies :)

These calipers have more clearance than the 328i calipers we removed. We unfortunately are not going to buy a bunch of wheels, and test for everyone. We believe these will fit just about any 15" wheel as long as you are not completely idiotic about offset/backspacing.

How does this effect brake bias? Do these have roughly the same stopping power as stock since they’re smaller rotors, but 4 piston calipers?

Not something we tested to be completely honest. I can tell you we have run these exact calipers on many different platforms, and they perform very very well. We expect these to increasing stopping power over even stock sized rear brakes, let alone the 328i conversions. A little more rear bias would not be a bad thing on these cars IMO. We had issues stopping on some 1/2 mile runs. This should help solve that.

If you want new lines to connect to your new calipers, we have that as an option. If you want your whole car to have SS lines -which isn't a bad idea- then you should replace those too, seemingly as common sense would dictate. While in there probably want to make sure you have good brake fluid too. Hell, at some point a roll cage make sense, which sadly is also not included in this kit. I'll talk to Tony about including that. :)

Just an update. Ultimate Brake kits for 335, and 135 are now in stock. We have two back orders we need to fill, and then we have 4 more kits on the shelf, plain, and drilled rotors. For the 135's we had to go with slotted rotors due to drilled availability.
