Brakes - ideas for 5x205 to 5x130 porsche (help needed)

[Black_65]

Hi Guy's,

Has anyone ever done 'wide 5' to 'porsche 5x130' conversions on empi wide 5 front discs and vw wide 5 rear drums?

I have a set of fooses to put on my strip/street bug and had the idea of getting the 'cone' shape milled flat and have the stud patten drilled.

Like it say's above, has anyone ever done this? or any pointers would be very helpful! I don't want to use adapters as im not sure if they are safe for racing and road use??? if they are then any makes you think are good to use, then please do list them 

Thanks,

Clarkey VWSP65

No can do on the rear drums, they must be replaced with 4 lug drums and redrilled.

I needed a brake update so I bought all new stuff with the porsche pattern --- if I had to do it again I'd probably go chevy pattern

Doesn't CSP still offer new porsche pattern drums?

Link pin or ball joint?

I'd sell what you've got and start a fresh, dropped spindles, Porsche discs & drums

It should sell quickly & you'll probably come out even

Can't vouch for the front but the rears should be easy even with short axles. Buy a set of Porsche-pattern drums or have a set of four-lug drums redrilled. Back in the bad old days we drove the studs out of a Porsche adapter and used it as a drill guide to poke new holes in drums. Spot facing the backside for studs is another story. We had a friendly machine shop do that for a sixer of yellow water.

Four-lug drums accommodate wider rear brakes so take advantage of that by getting some matching backing plates and hardware. You'll feel the difference.

Four-lug drums fit an axle with a broach length approximately 5/8-inch longer than a short axle's broach length. You'll have to make up the difference with a spacer between the drum and castle nut. The bearing spacer on a swingaxle car is 15.4mm/.607", or .018" shorter than 5/8. Just orient the chamfered side to the drum. It's been close to 20 years since I done that so I might have missed something.

You have Foose wheels with a Porsche pattern? That's a weirdo setup. If you have to buy wheels then do as fiatdude recommended. But I'd say to go Ford/Chrysler 4.5 pattern. Wheel availability is far better than in GM-only 4.75 land.

Pretty sure he meant Fuchs...

Probably correct . . . list the "empi wide 5 front discs " for sale someplace and get a disc set with the Porsche pattern. There is a set that will bolt on to your stock spindles.

Unless I'm wrong, the spacer would be required in the opposite case . . . early, wide-five drum on a late, long-spline axle.
new drums are available with the porsche pattern. When I purchased my new drums, I had to pay $10/drum to have the hubs turned down to fit the short splines.

Yeah, disregard my post. I drank a bunch of cough syrup just before I wrote that.
