Lets get back to this offsetting car geometry... I am also running the 997s wheels. The car feels much better, more planted in turns with the extra inch of rubber in the rear.

Now I am not taking it racing, are you talking about on the track its not as balanced?

So a 19" rim, with the same width and offset as an 18" rim causes a difference in geometry, just because it's 19"?

I don't see it

They may be referreing to the fact the the Carrera S rim has a different offset at the front by 7mm.

Now that could make a difference, but in practice I find it drives just fine.

If I wanted, I could add a shim/spacer and bump it out to the same as 996 spec, which cohare may have done?

Other than that I'm mystified

Anyone got any other thoughts?

I havent added the spacer yet because I have not seen a need for it either... Other than the offest difference I would have to agree I dont see how it could matter.

Don't 19" wheels add a bunch of unsprung weight? With the roads in Los Angeles, 19" wheels would be ruined in about three hours.

cdodkin

Weight is the same as 18" I believe - no extra unsprung weight

I've driven in LA, and so far no issues.

Having said that I do avoid the pot holes!

Not possible, but they're probably only ounces heavier.

You must have stock suspension then.

cdodkin

This is true!

I think with lowered suspension, you'd be in for a hard daily drive!

With std suspension, it's nice and firm, without being uncomfortable.

It's not so much that it's a hard drive, but you can definitely feel the wheels being abused. It really pisses me off how bad the streets are here. If I had known they were this bad I wouldn't have purchased my car.

I am not sure about LA streets but I live in downtown Baltimore and the streets even feel $!tty in my 04 Maxima I know how you guys feel. No problems with the 19's yet ..knock on wood..

19s...... the only way to go on the 911.

Awh, come on! Ounces? I'm sure there are some very ugly lightweight forged 19" rims that are lighter than the stock 18's.
