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?

Dr Phil,

Correct on front setup. You need the hubs and brackets. You can get some nice screw in studs from BMW shops or 034 motorsports.

Correct on rear setup, you'd just need the radial adapters. The 914 hub will accommodate the Cayman caliper without any work. Note you lose the parking brake.

I have this setup on my car (vw) with 19mm master and works well. It's been on there for over a decade. I'd suggest maybe a slightly bigger master (20.6) if you want a really tall pedal , but I've left good enough alone.

On 16 fuchs the calipers need a little massaging, and maybe a slight spacer 5mm unless you have the 951 Fuchs. Pic of massaging here:

In general you need 16" wheels. Some 15s fit (mainly the spare tire alloys such as 928/993 15" spare or 951 spare

Thanks

@Lanner Are those calipers S or just repainted? Lanner your bug is awesome. I have loved the "German Look" for years. Every now and then I watch videos of Bugs with big T4 engines hunting Porsche. (IMG:style_emoticons/default/shades.gif)
