Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.
Leading evidence: 'Use 18"' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Use 18"' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Brothers: I am currently thinking of performing a wheel upgrade from my 18" Classic Stock Wheels to 19" SSR GT Wheels with Kuhmo Rubber. My question is simply this, are there any negatives with going to 19" ? Are there any benefits ?
More unsprung weight, prone to damage, increased stress on the chassis......19" are not a good idea IMO. Why do you think the racers use 18"? Leave the 19s for the posers. Just my .02, you asked.
But they sure do look good on the other hand.
Dj 996 is right about that it may weigh more and more prone to damage. It depends where you drive the car. If there are lots of bumps and pot holes then the rims can get damaged a little easier than 18", but not much 18s are pretty prone to damage too. You will not gain any handling. If you do it it will be for the looks. If you like the looks them go for it. If you think it will help handling than don't do it. I don't see how can it stress the chassis more. I mean the SSR are relatively light I don't think they can weigh 3-4 more than your current set up so I would not worry too much. If it was me I'm stuck in the same boat. I like the looks, but I DE the car and like 18" cause there are R compound tires.
ssr's even the 19's are half the weight of porsches lightest wheel, so i doubt your adding any unsprung weight, but then tire's and bending the rims would be a problem with light weight rims of that size
May Issue of Excellence magazine, page 58, explored this debate closely.
".....We will only do it in 18-inch because the suspension design of the 996 is such that - if you use 19-inch wheels - the wider tires and stiffer sidewalls create more geometry problems than they solve on bumpy roads. I agree they look better, but we are all about performance and driving qualities here, not posing!"....
I don't know which SSR are you quoting and what size, I know for sure the SSR GT3 19" weighs more than 20 lbs. I don't even think BBS magnesium wheels in 18 " are 15 lbs. Of corse I may be a *****
well the 18" SSR competition wheels i have are only 14lbs each, and im deffinatly a *****, but atleast i didn't have to try and insult anyone because i thought the lightweight porsche wheels where heavier than the ssr's
