Yes, I agree. Maybe orange mirrors or something.....Nice....ballsey.....I like it

 

Dont go overboard with too much orange...its a fine line buddy. Looks ok as is

 

I can hardly wait till adias sees this .

Just make sure you report those changes to your auto insurance because with this wheel tire combination they may deny a claim if you lose control.

 

Look good!

 

uhmm not convinced about that

 

Agree with that!!

 

I'm wondering if i could fit 325-25-20 on my 20x11.. On tirerack it says 11.5-12.5'' but they also say 11-12'' for the 305-25-20 and the tire is streched already. So maybe it could fit.

I kind of brutalized the car a little in an empty parking lot tonight, just to see how the car reacts now ''under pressure''. It's day and night compared to the Hankooks. The Pirelli's are much easier to control when the rear-end starts to drift. Overall cornering stability is excellent. Besides the grip and the steering response the most noticeable change is really the predictability and ease of control when pushed hard. I feel way more confident with the car now.

I was a bit afraid by going from 235's to 245's on front but it's very good. The car feels planted to the road and is very stable at high speed.

Like someone said previously, maybe on wet roads it will be different. We'll see.

 

Superb!

I was thinking of doing a similar color thing with new wheels but I have an Arctic Silver car. Any suggestions? I'm so over black wheels on silver cars so trying to think of something different.

 

whoa - that really wakes up the gray. hmm...is the rest of the car now too sedate for those shoes?

 

Nice look but kindly remove the fron t plate.

 

I've been thinking of trying 18 front and 19 rear for a while.

I always thought the wives tales about matching front & rear tire brands was a lot of hooey. The fact is the traction characteristics of the front & rear on the 911 are so vastly different that adding another difference is not a big deal. On a balanced car like a Cayman I think you would notice it a lot more.

 

biggest tire for 11" rim would be 315. on 12" rim - 345.
you can stretch tires to crazy extremes if you are after some speciic effects - some folks run 275 tires on a 8" front rims.

I do not think you did a smart thing using 20" rears. I just do not see what it was you gained. you definitely lost plenty of acceleration by going to 20" from 19", most people go other way - to 18" and there are pretty obvious reasons for that.

But if yours is a street only car that will never see any extreme driving - you will be more than fine.

to really see effects of your changes you need to take it to some time tracking events and try different configurations there.

 

for silver best color is when rims are covered by 1mm of brake pads residue that makes them look like gunmetal or so. charcoal?
Orange would be too contrasty imho. dark matt grey is the best with silver nd it masks dirty wheels perfectly - no need to clean them.

 

Jon - I actually like the look, it's different and not for everyone but tastefully done.

As for the tires and different rim sizes you definitely changed the dynamics of the car, but that doesn't necessarily mean in a bad way. The Yok's are good tires but they are soft and not 'N' rated. They are a great steering tire though so you may be on to something. The Pirelli's in the back are a great choice for obvious reasons. All I can say is there is a lot of science that goes into treads/compounds these days and the Porsche is one car that benefits greatly from design.

My bigger concern is your car is raked now right? That to me would upset the balance much more than the treads. I would think this would promote more oversteer with such a heavy rear-end, so be careful and keep us informed of your results.

I have no problem with teh color or even mixing 20 rears vs 19 front.

The different compunds however doesnt seem like a sgood idea, especually when wet or if you are reaching the limits of adhesion (panic stops and spirited driving if you have the place to do that).

Yeah, the different compunds make me nervous.

Good luck.
