I need some advice please, so I also posted this question in the cup car section

I can buy a used set of BBS E29 wheels from a late 996 Cup car
naturally these are centrelocks wheels
centers are 0229052

but can all of these wheels be drilled to std Porsche 5 lugs?

I want to fit them on a street/track driven GT3CS but rebuilding this to centerlocks is no option as I legally can't do this on a street driven car.

I'm asking for some advice on this matter before I buy the wheels.
at the back of the wheel centre, 15 blind holes are already there, so drilling an extra 5 holes for the normal set up, will this not weaken the wheels too much

or are these 15 blind holes at the backside already the correct size for the regular wheel bolts and pattern?
and in this way drilling them through will work without reducing the wheel strength too much

thanks in advance

Hans

 

Here you go:

 

THX

how do they look from the rear?
as these have a lot (15) of blind holes in the back and they do not look fully aligned with the spokes

 

Why are the CL's not road legal?
