Can we convert 5x130 to 5x100?

Can Porsche rotors and hubs be modified to accept 5x100 stud patterns?

Depends on the hub. I've done a rear 944 setup that was machined for 5-114.3mm. Don't see why I couldn't do 5-100. In the front, typically there just isn't enough 'meat' to machine the 5-100 pattern, since the Porsche hubs are not solid between the existing studs (in an effort to reduct weight).

Now, if you had some custom billet hubs, anything is possible. If only you knew a guy who could carve aluminim.....

What a shameless plug

What had to be done to modify the rear? Is there enough material there to support the 5x100 pattern?

I am purchasing some as we speak but haven't actually seen them in person.

For the rear, I machined the hub for the new bolt pattern. The back of the hub was spotfaced the head of a stud. Studs were pressed in. Clearance holes had to be drilled into the rotor. 5-100 should be no problem.
