Thanks, everyone for the insightful commentary. I certainly have a lot to think about. The really good thing is that I do have a set of 18's, so, I may be able keep them for any track work that I may do and get the 19's for the street.

Decisions, decisions... Maybe I should start another thread looking at performance mods?!?!

 

Performance is easy, Bilstein PSS10 for corners, VFE supercharger to go faster, Gyro slotted two piece rotors to stop faster. Remember to upgrade to Motul or Super Blue after modifyong the brakes (you don't want to learn about boiled fluid approcahing a corner at 130 MPH).

 

It's even easier than that! Slap a few "Type R" stickers and that should be good for 20hp per sticker!

 

Looking for performance mods?

Easy, first scrap the 19" wheels and tires...

LOL

 

I say 19's (unless you're going to be driving the car at it's limits). As for tires, go with 245/30 in front and 315/25 in the rear. Add some coil-overs and I guarantee that it will look sensational!

its pretty obvious!17 inch or 18 inch,thats the way it comes,that is all!

 

Not trying to start a firestorm here, but, I find a lot of the comments interesting. Much is mentioned about how the Porsche design engineers have set the car to PERFECTION, yet, many make certain mod's that they deem necessary - performance being the biggest area. IF the car comes as intended from the factory, why does Porsche have a list of "hundreds" of options when you order the car? In speaking w/ the dealer, they often mention that the option list is so long b/c they want to give the owner the opportunity to make each car unique.

I'm not saying I know everything (far from it!!!), but, is it possible that the factory did not include 19's as an option b/c the technology and tire combos did not exist that Porsche felt comfortable with up to 2005? You have to admit, before 2005, there were not a lot of street cars in any category running around with wheel diameters greater than 18!

In speaking with some of my friends that track cars extensively, they have stated that the most noticeable difference on the track is a slight loss of power on exiting turns. BUT, due to more rubber contact - 315's vs 295's, there is a slight gain in grip, which could be negated by less flex due to tire wall height!

I guess there is no right answer. I have to say, though, the opinions are very helpful.

 

For bling factor, 19's are just the start. 20's are common on almost any "sports" car. Camaro's, Vettes, Vipers, NSX's, etc.

If any car is to get DE'd, AX'd or tracked..then weight and wallet content become part of the equation.

On larger sedans.. it's a matter of choice...Cadillac, Lexus, Infiniti, Acura, 7 series BMW's are riding on 22's.

Forget SUV's, 22's and up.

 

I don't believe that 19's will be better or equal on the track...you need a softer tire compound and taller sidewalls which are the more important advantages of 18's on the track. I'd keep the 18's for the track and do the P40 (Brushed) for the street...widebody begs for lowered on 19's for the proper street look.

 

... and that would be?????

 

see examples below...

 

FLY996 from your avatar I see that your wheels are set up nice & tight. But not the case w/ a couple of the other examples you posted.

Once the top of the tires begin to disappear into the wheel well, it turns the car into a caricature of itself & looks goofy IMO. But to each their own...

 

Agree 100%! I'm a purist and I wouldn't hesitate to run 19's on the street.

17" will not fit on a C4S due to brake set-up.

 

Very interesting comments on this video. Note that what the driver says does not match the results. I know that the test is done on Japanese cars by Japanese drivers, but, I would say valid nonetheless.
