Porsche 5 lug rim options?, Are all Porsche 5 lug rims the same? Options

[pnewman]

I am looking into buying some newer used Porsche rims. i.e. Boxster, 911, 993?

Do all 5 lug Porsche rims have the same size pattern?

what is the max width 7" or 7.5"? What is the max height rim 17" or 18"?

rim hieght has nothing to do with fitment, it's the tire diameter, figure the larger the rim, the less sidewall the tire will have for the same diameter tire.

for stock fenders you want an effective offset of 35mm for a 7" wide rim and 205 tire (I'm running 17x7 with 205/45's) , most of the Porsche 17" rims have a 55mm offset so you need a 20mm spacer in the rear or the tire/rim will rub on the trailing arm or the inside trunk wall or be pretty darn close to it....

for the front, without a spacer for a 55mm rim, the tire will hit the strut....

unless you've been racing for years and your suspension is setup perfect, you'll never really notice the performance difference between running 17" or 16" rims if running the same brand tire and close to the same size....sure you might notice the car running stiffer on the 17" rims, but chances are going into and out of a corner your speeds will be the same....

there are guys here still running 15x5.5 rims with street tires that'll clean our clocks at the auto-x or track (IMG:http://www.914world.com/bbs2/html/emoticons/MDB2.gif)

for best performance, the lighter the rim/tire combo the better.....
