i have a MY2004 Cayenne v6 with 17x7.5 rims. I have the opportunity to purcase 2004 cayenne turbo rims 19x9. Has anyone had any experience with this? what happened to ride quality? was an adjustment necessary to the speedometer? did you need spacers? do you recomend the spacers?

thanks

The turbo rim is 18" not 19". Did you mean the design rim? As a contributing member you can see the approved wheel TSB. The 18's ride good and are probably the most common cayenne rim overall. I think you can adjust the speedometer in the settings menu in the dash (I've never done this but thought I read it somewhere on here).

guess you dont have air ride? me neither, and since I've tested, drive, owned, all those 3 measures (besides 17" which doesnt work for the v8 peppers) 18", 19" and 20" - I can tell that you will feel the differences in ride quality with bigger wheels, as you will earn better handling but more bumppy ride. So, dont know how are the roads on your area, but if you have good ones, you can go for 19", also 20". if the roads are bad, stay with 18". as for the visual effect you might consider 20" sport tehno.

also, you DONT NEED to: - use spacers at all - these OEM wheels will clear your calipers by far

- to adjust your speedo; the overall diameter is almost the same,

Tire - 235/65R17 -- Speedometer Difference: 0.000% -- Actual Speed: 60.0 mph

Tire 1 - 255/55R18 -- Speedometer Difference: 0.069% too slow -- Speedometer1: 59.9 mph

Tire 2 - 275/45R19 -- Speedometer Difference: 0.976% too fast -- Speedometer2: 60.5 mph

Tire 3 - 275/40R20 -- Speedometer Difference: 1.255% too fast -- Speedometer1: 60.7 mph

good luck, and dont forget to post pictures when is done.

Wow are you right about the ride quality on the 20's. I test drove an 05 CS certified last night with 20" sport design rims and standard suspension and that thing was the worst riding vehicle I have ever been in. I actually thought some interior pieces, which were rattling heavily from the potholes, might fall off from the rough ride (I am in WI and our roads are almost nonexistant from govt neglect and harsh winters). While visually 20's are appealing the 18" ride is a million times better on rough roads!!

It is nice to have PASM if you have 20" wheels. I generally keep mine on "sport", although sometimes it gets very harsh, depending on the road. It is nice to be able to switch to "comfort" when necessary. I don't think I would buy 20" wheels withouth PASM.
