Recommendations for the best bang for the buck BBK for street/occasional track use.

[RAFFF]

What's going on fella's. Just got a 09 e92 m3 with 19" 220m wheels, the car has stock suspension and brakes. I got my hands on a kw variant 3 coil overs, soon I'm gonna invest in a BBK. I'm gonna have them installed together so I got some time to try and figure out what direction to go. Just curious which kit are you guys truly pleased with.

Brembo GT is definitely not bang for the buck unless you can find one used for cheap.

There is a guy on here who's selling a used Alcoin bbk for $4500, but its been rebuild so that kind of concerns me. What do you think of the StopTech bbk ?

ST40/60 front setup, OEM rears. Swap in pads for the track, change your brake fluid to something like RBF 600. Should be pretty budget and ready to track after that.

Stoptech and. Racing Brakes (that's the name of the company) I think they both make fronts that are balanced with the OEM rears.

Thanks for the tip! I don't know if id want to leave the rears stock. I want to buy a kit front and rear just trying to figure out which ones to go with. What I meant for (best bang for the buck) is the best deal on a complete BBK package. Besides improved track performance, I love how they look.

I truly don't mean to thread jack, but I am also trying to upgrade my brakes and I've been advised by both MRF and EAS (two of the biggest and most trusted shops in SoCal) not to go with a Stoptech kit because of the problems that shops have had dealing with parts replacement (pads, rotors etc.) and issues that arise from their kits. Can any owners chime in on this? I've been advised to go AP or Brembo, but their kits are significantly more expensive.

AP would be my first choice, but I'm biased.

I’ve had my ST-40 /ST-40 kit since 2016 I do a lot of Track Days and haven’t had a single issue, Even last year When I did 16 Track Days and never had any breaking issues whatsoever....

I've had stoptech on a previous car, daily driven. Overtime I noticed the hardware and bolts were corroded. It made pads changes extremely difficult. I also experience the bridge being so tight I had to pry it out aggressively. Since then, I've appreciated brembo's pin and spring design.

The machined studs back out of the caliper adapters on StopTech brakes when you try and remove the calipers. It's happened to every set I've owned, I think four now. The adapter is billet aluminum, the stud SS, and the nuts have a zinc coating on them and bind up for some sciency/heaty reason and it's very annoying, I would imagine servicers hate them for that, they need threadlocking back in and then you need to sort new nuts out to hold the calipers. Bit of a nightmare if you're in a time pinch on a job. I still buy ST because I don't need to remove the calipers very often and they're good value for the $.

Brembo GT fronts have fixed bridge, the caliper needs to be removed to change pads.
