Vented Rotor Stock Strut, Yes it all bolts on Options

[djway]

It was suggested I make this a stand alone thread so here it is. This will work for 4 or 5 lug wheels.
Parts
07,08 cayman, 05-08 boxster 2.7L (non-S) rotors.
298x24 front
299x20 rear.
Calipers 97-08 Boxster
07-08 Cayman
Adapter mount for rear caliper. Re-drilled rear hub or the soon to be released 5lug hub from URO. If you want to keep 4 lug have the Boxster rotor drilled.
Front hub that goes right onto the stock strut and can use 4 or 5 lug wheel. Front rotor mount adapter.
I have not tried but am told 15” alloy works.
Rear

Front



Once the URO rear hub is available (announced Nov 2020) this entire upgrade to Boxster brakes with 5 lug will be an off the shelf bolt on affair.
edit I believe it can be done for both early and late struts. the struts shown are late which was harder to work out.

Hi guys,

My name is Lanner. I built this setup. It uses new iron hubs with radial brackets for use with stock 914 spindles. Bearings and wheel seals are stock 914 and it's bolt on. It's a good option that doesn't require swapping out to 911 suspension. Please let me know if you have any questions about the setup.
Thanks

i do have a couple questions, since i have 5-lug fuchs(16") , but used the stock rotor and brakes in front with the rotor redrilled and new lugs pressed into the rotor, so currently i have all stock set up, but i do have 19mm 911 master cylinder, so my question is this: for my front if i converted over to this set up , what would i require? The boxster caliper and rotor, and the hub and spacer mounting blocks, is that it? and then source the new studs?(i want to use nuts not lug bolts)
@Lanner @djway


also fyi i have 914/6 5 lug hubs on rear so just using the stock caliper with stock 4 lug solid rotor drilled for 5 lug(PMB), so for rear i would just maintain my current set up , or, if i wanted the rear boxster caliper would i just get the new rotor and caliper and mount with adaptor block? seems the new rotor would just slide right on my current rear hub but new caliper with spacer would be required, OR a 914-6 or M caliper could be used too?

Phillip - this looks like a great solution for putting big brakes on a car but I would hesitate to say it’s the solution for every car. I would put a Carrera rotor next to your stock rotor and check the weight difference then X 4 for the car. Adding pounds of unsprung weight to a narrow body four will affect acceleration and handling. Everything is a trade off and it really depends what you are trying to achieve.

We did the Boxster caliper, Carrera rotor upgrade on a lot of 911’s that got 3.2 or 3.6 engines. It’s a nice upgrade from M calipers.

S calipers have 3.5” spacing and are different from Boxster caliper spacing.
