Heavy wheels will ruin your suspension. Heavy wheels with the wrong spacers will punish your wheel bearings AND suspension. If you track or autocross then you definitely need to speak to an experienced professional about your set up. Correctly spaced wheels will not damage your suspension, nobody is claiming that. But all too often I see people buy a second hand Porsche and slap on heavy aftermarket wheels and spacers. The car is now slower off the line and your giving some very expensive parts a premature death.

Are these 18" Turbo twists with rear Boxster fit or are they possibly the solid spoke twists from a 996 Carrera?
If the latter, those are not the lightest wheels, they're nearly 30 pounds.
