The early cars, such as the 97, had a TSB out on them warning against using wheels larger than 17" which can cause chassis cracking near the suspension mounts. This problem was corrected in the later cars by reinforcing the chassis areas with thicker metal, which eliminated the problem. And while I'm sure someone will chime in that they have been running 22's on their car without problems, we have seen more than one car with chassis cracking from using bigger wheels.

Instead of covering up a faulty structural integrity simply caused by down-force on the '97 (in my uninformed opinion mind you). Unless a silly wheel is heavier than the constant downforce these car cope with at speed then I'm clueless man |
Porsche did actually put out a Technical Service Bulletin (TSB #4407), dated March 4, 1997: " Eighteen inch wheels are not approved for use on Boxsters. Use of eighteen inch wheels on Boxsters under severe conditions may result in structural failures of the body and/or suspension". They later beefed up the suspension in later model Boxsters to handle larger wheels. Regardless, people have thrown on larger wheels in their early Boxsters. Your car, you decide. Original poster should still be able to sell the wheels as they should be fine on later model Boxsters.

Is this really the official bulletin/writing? That's it?? not trying to be sarcastic here, I've never read it. What is the wheel weight "difference" between a cast stock wheel and an aftermarket? Not much compared to the groceries bags she place in her back trunk basically (chassis/suspension right?). Please do not make me show you a graph of the downforce curve these cars goes between 60~100mph LOL This wheel size thing you read everywhere just doesn't make sense to me. Thread hijack, sorry Stangit66 |

I think it's more about lateral forces exerted on the suspension and chassis in cornering than it is about weight. ;)
Larger wheel = more leverage on parts. |

When did Porsche update the chassis and/or suspension? Do '99 Boxsters have the reinforced components?
