Stock Porsche wheels are very robust. If you bent one, you hit something very hard. Get a replacement wheel. Once bent, the wheel loses strength and they can never be straighten completely true. I just had my 3 pieces completely rebuilt (new inner and outer barrels) after hitting a obscured speed bump. No visable damage but all wheels out of round. I also got rid of the chromed outers (too many bead leak problems) and went to high polished clear coated. It's not worth risking your car and life to save a few bucks.

 

I know such places exist but I would be very nervous at 190mph trusting the welded wheel. Probably just a psychological barrier, but it’s the same as plugged tyres. They work fine but your head is telling you otherwise.

 

I think I might have spare stock wheel in my garage aswell
