    Brake Upgrade for BMW Euroweaves / BBS RS 15" --- Is a BBK Worth it?

    ​Brake Upgrade for BMW Euroweaves 15" / BBS RS 15" / Other 15" Basketweave Style


    Having driven my EM1 (2000 Civic Si) on a simple "BBK" which was really just Wilwood Calipers - I grew to really really like the additional pistons, braking power, and feel.

    Is it worth upgrading brakes to a BBK if you want to run euroweaves or other 15" basketweave style wheels?

    The euroweaves are too classy to get rid of for now, so I'm struggling thinking if a BBK (front) is worth it, but stock E30 brakes are a bit meh IMO. [Click and drag to move]

    I'm also considering upgrading so a future engine swap doesn't necessitate the upgrade then, rather do it now if I'm gonna do it, since suspension and other things are going to happen soon.

    I'll be switching between 15" euroweaves and 16" wheels, rotating them every once in awhile.





    Now saying that I've done some research, and I know there are some options, if I'm missing something worth checking out let me know.

    e30 front 280x21mm /11"x 0.8" BBK

    Basic kit - Caliper adapter kit includes aluminum mounts, hydraulic fittings, BMW setscrews and fasteners and allow to fit a Wilwood Dynapro #120-9703 caliper on a VW Corrado G60 disc. The basic adapting kit is $250.00cad. Reintroducing the two-piece rotor - You can now fit 11"x0.8" two-piece Wilwood rotors #160-12892 if you can't access VW rotors or want to reduce weight and improve cooling ability (most G60 rotors have a closed backface, hence making impossible the use of ductings). And saving you the process of having to enlarge the Ø65mm center bore to Ø66mm. The full adapting kit (caliper brackets and hats) is a direct bolt-on and costs $600.00cad. Hats alone (with fasteners) are $450.00cad. Calipers and rotors available from any Wilwood supplier. This kit fits 15" BBS RS or other so-called "Euroweave" without spacers.

    For the 318/325. This 295mm front big brake kit is intended for cars with 15″ or larger wheels. Rotors are slotted 2-piece with aluminum center (hat) measuring 295mm x 20mm. These are very effective and reduce unsprung weight. This kit uses a Wilwood forged aluminum 6-piston Dynapro caliper – this caliper is 1/2″ narrower on the outboard side than most calipers so it’s less likely to cause wheel fit problems (you need only 1.75″ from the rotor to the back side of the wheel spokes to clear this caliper). The inside diameter of the wheel needs to be at least 13.375″ to clear the rotor. Kit includes 6-piston Wilwood Dynapro calipers, two piece slotted rotors, brake pads, mounting brackets, associated hardware, stainless steel braided hoses (note that others do not include this in their kits).

    Note: Picture shows optional cross drilled rotor.

    Currently, Wilwood is experiencing production delays due to raw materials availability. There is a shipping/processing delay for this kit of 8-10 weeks.


    Total Cost: $1,290.00 + Shipping ???

    Worth it?

    Requires 8mm/10mm spacers.

    Following this thread.
    Also would like to keep 15" Euroweaves, and eventually will need better brakes.

    FWIW I switched to an E83 X3 Brake Booster w/Chase Bays proportioning valve, and it made the original brakes feel much better. I don't have ABS just as a point of reference.
    Haven't had it at the track since the change though.

      Good to know, I have ABS and want to retain it but a new Master + Booster are likely in my future - would love to have the plan sorted before an engine swap.

      I just would love to know if a mediocre BBK would be worth the cost from those who have any of the above options.

      While I'm not against running spacers, and I may just for aesthetics, I'd love to know that the euroweaves would fit without them. With they above options that should be true, but again would just love some confirmation.

          Sadly, you may be better off posting to the R3VLimited FB group.

              280 or even 295 is pretty big for the size of the car. an R32 GTR is only 325 x 30. bigger yes. but a GTR is significantly heavier and more powerful standard.

              i feel like either options would be more than sufficient. The spec E30 guys all use OEM size afterall.

              what about the rear brakes?

                Just a better pad compound on the stock E30 calipers improves braking a lot.

                The Massive kit with the Wilwoods would make the feeling a lot better since its not a sliding style caliper. Lees stuff is solid so you know its going to be a good kit!

                I don’t have the kit so I cant comment on how it feels. All the PRO3 cars run stock calipers with good ducting. If you drive the car hard, the ducting is key to cool the brakes down between applications.

                  I think there's a risk of messing with the system and making things worse.

                  Changing front without rear, or without considering the rear - will it change your F/R bias?
                  If you have better brakes up front but end up only using half the rear brake you were before, will this actually stop better?

                  Is the piston area changing a lot -> will you end up changing master cylinder -> What fits your booster and what size is the F/R MC and how does that change your brake bias/pedal feel/pedal effort/travel?


                  It would be easy to do up a spreadsheet and I've meant to do this forever, but haven't got around to it.


                  Also it's hard to compare different kits because the calipers themselves are hard to compare and wilwood doesn't seem to have a strict "x caliper is better than y" list.
                  Basically it seems like the best stuff going are the radial superlites, then the dynapro/dynalites have considerably less structure to them, but are cheaper and probably lighter?
