Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

hey guys
im trying to see if i can put 20" on my 2002 C4S widebody.
FRONT TIRES ARE 245-30-ZR20 AND REAR 305-25-ZR20
this set was fitted on a 997 narrowbody, just wondering if it will fit my c4s, i know i might need rear spacers for them.
thanks
As a die hard Porsche fan and once owner of the
997.2 GT3RS
, I think this is the absolute pinnacle of Porsche cars this is the new GT3RS. Now that is been a couple of months and owners have taken delivery of them, the modders are out in full force trying to fit, develop, and install performance and styling components. The new 911 GT3RS really does not need anything. As a race car in a box, it would be silly to try to out do Porsche, or is it? The folks at HRE Wheels decided to show us what a set of
HRE wheels
would like on the new GT3RS with these renderings. They feature the 1 piece forged wheel design
P101
and a multi-piece cup style wheel design that is derived from the
C1 Series
. Having used HRE on a handful of our own Project Cars including our
997 Turbo
,
CLS63
, and
C63
, we are very in tune with fitments, styling, and what we think would look best on your ride. Enjoy these 991 GT3RS HRE Wheel photos and make sure to contact one of our Performance Specialist with any questions regarding wheels for your Porsche!

Yes with spacers as you mentioned. After this it will be more a show car I would imagine as you've already taken a weight penalty with a 4s in the first place coupled with heavier 20's. Dont forget to get the "DUB" sticker.
Not sure why you'd buy a high performance car and immediately take steps to reduce its performance - and make the ride quality suffer at the same time. Looks are subjective, but I think dubs look silly on these cars.

Most of us, including myself will never experience the full potential of these cars especially living in Los Angeles which I do. With the 20's I have NEVER felt any reduction in handling or comfort with my day to day driving. If it was a track car, which mine is not, completely different story. Its a personal preference/style thing so to each their own.

He stated it rubs against the front panel.
The way to fix this is to get proper wheels and be done with it.
It's like a girl that wears 5" heels and miniskirt in the winter wondering why her feet hurt and complaining she is cold. Lol
If it's rubbing against the front panel the only way you will be able to remedy that is to change to a smaller diameter tire. This will mean a lower profile and it's really going to give you a rougher ride.

Not possible in either 225/235/245 tire sizes as OP is already running 30 size sidewall. I couldn't find any with a 25 or less sidewall size in the above width.
By then, you're on rubber bands and not too many places are gonna be able to even mount them let alone having to deal with bent rims every year.
Depending on front wheel width, OP might see if going down to a 235 or even a 225 width would resolve the issue.

I'm sorry for some of the mean comments so far...
Your tires hit the front panel because they are too tall.
You can either
1) heat the fender liner and push in
2) buy new tires which are shorter, eg 235.30.20 or 225.30.20

245/30/20 = 25.8" diameter
235/30/20 = 25.6" diameter -> decrease of 0.2"
225/30/20 = 25.3" diameter -> decrease of 0.5"
assuming you have one of the fitments found here
http://vancouver.en.craigslist.ca/rc...550562129.html
I would run
235/30/20 or 225/30/20
295/25/20
good luck
Quote:
if you have a C4 or C4S, that is not ideal. there is a 1.7% difference in diameter.
you could try it, but risk damaging your differential
you should post a pic
