20" wheel issues???

So I was talking to a friend, telling him I think I want to put 20" rims on my turbo. He said that sounded like a bad idea. I said the 19'
s don't fill the wheel well enough. He said that's because I haven't lowered it yet. Thoughts? Experiences? Will the speedo be able to be calibrated to the 20's? Any other foreseeable problems with this?

I run a set of 19's and a set of 20's - both look great lowered. No issues with either set.

Get whatever makes you happiest - the car rides a bit better on the 19's with the bigger sidewall.

My 20" wheels with 245/30R20 and 325/25R20 tires have the exact same diameter as factory wheel and tire. They're also lighter and have absolutely no problems.

When you increase the wheel diameter you must decrease the tire diameter in conjunction with that. The rule of thumb is to no deviate more than 3% from the OEM wheel/tire diameter. If you follow this rule then you are in fact eliminating hardly any fender gap. He is correct that the only true way to get rid of the fender gap is to lower the car. If you try to get a bigger wheel AND a bigger tire ingoring the 3% rule just to fill in the fender gap then you risk absolutely destroying your transmission and the very sensitive Porsche AWD system.

If you need help in choosing the correct wheels & tires for your beautiful Turbo let me know. As you can see here we have tons of experience - http://wheelsboutique.com/gallery/po...s/porsche-997/

^^ This 100%, and why I had them setup my 997.1, and other cars.

I'm running 20's with H&R, and TPC module. Zero issues.
