Default Porsche Cayenne brakes on a 240? Sure

GROUP BUY HERE! http://forums.turbobricks.com/showthread.php?t=286247


Well. It works. Pedal feel is fantastic, firmer than stock 240. Modulation is excellent and its quite capable of throwing you into the dash. I haven't tried to lock up the 245s yet.

Details.

Front calipers. 17Z L and R from a 2005 Porsche Cayenne V8. 6 pot (330mm rotors)
Rear calipers. 2005 Porsche Cayenne V8. 4 pot
Master Cyl. 1.0625" bore from a 1994 Mustang GT
Rotors. S60R front and rear. Brembo.
Pads. OEM Pagids all around.

The adapters were designed by me. I'm considering doing a run of kits for this conversion. Overall the pricing is on par with the S60R brembo swap. Can be a little cheaper if you get lucky on ebay.

Because of the staggered pistons and the fact that on the Cayenne the calipers are mounted leading edge, I had to flip the crossover pipes and bleeder screws to retain the even pad wear.






Comparo.


Removing unneeded lines and draining fluid.


Always helping.






I notched the brake line holders so I can swap strut tubes when I fancy up the suspension.


Crossover line removal.






Rear 240 rotor with the rotor portion cut off. This retains the stock parking brake.






Trimming the backing plates to fit.


(The bleeder screw was just a dust plug)




The patient and owner.


Master Cyl.


Wat.



The only modification needed is extending the pushrod on the booster. ~.8"


The rear port is M10 bubble flare, front is M12 bubble flare so a reducer is needed.


Yes the triangle is coming out.


They're there. Hiding. Waiting.

Nicely done my friend! One of the problems with the R calipers is they are technically backwards and instead of crossover tubes they are plugged. Well a few of us tried and the plugs are impossible to remove. Glad this worked out!

Do the outside edges sit more inwards then the s60r calipers? I don't really know how to describe it...

I know what you mean. Outside face of caliper to outside face of rotor. Not sure. I've never had an R caliper in my hands. I can measure if you want though.

I'd be interested in that measurement. Then see f someone with an R conversion could do the same. Or I'll measure on the next R that comes through the shop

Material is 7050 for the rears and 7075 for the front. They hold the calipers all good.

I was guilty of skimming your post, did not read.

you made and designed them.

I have been trying to decide which way to go with my brakes.

Do you think this will fit under borbet type-e's?
16 x 7.5, 20mm et at the moment.

Typing on my phone on the train, excuse the brevity.

Almost certainly no way they would fit under 16"s. Not without a smaller diameter rotor.

As towery said, they will most definitely not. 17s are a min.

Good question, it will not. I've got a random 17" volvo wheel on the way. I'll have to get one spacer made. But it's just about the same price in the end as a S60R spare. I'd rather have the full size spare.

Excellent work! I like the tip for retaining the rear parking brake. I was looking at a couple options for brakes for the '77 when I get to serious wrenching on it, and that just might suit my needs.

Whole set-up looks great.
