Hope it's not a tumor or anything like that. Maybe you just need new glasses.

I wish it was that easy. I cough, sneeze or bend at the waste I might as well just die.

Evening Y'all,
Well after working all day I went to a friends house and replaced all the brake lines on a 194something Jeep. I really need new friends

Nah you just need to make them wrench

My friend trying to wrench is the reason I was called in.

At least when I call you get a good laugh.

Two and a half weeks until the next work-cation. Can not wait.

Good morning everyone.

I went over to a friends place and borrowed some tires and wheels. 17 inch wheels!

The rear tires are 255 45 17s. (I had 225s 15s on it now) Dang they are huge. It will raise my car up a lot and stuff the fenders full. I will get them mounted tonight. I suspect the increase in mass and diameter will make it feel like it accelerates like a slug.

I just want to play with that size of tire and see if I can get used to it. I am on the hunt for some 17 or maybe 16s. I can't find any tires for my wheels. I will for sure look for tires one more time before I buy those giant rim sizes.

My garage queen came with the factory 16" wheels on it, and I bought a set of 17' wheels a while back. When my current set of 16" tires either gets long in the tooth or wears out, I'm going to pick up a set of 17" tires for it. No looking back.

I just figured for the cost of driving over to his place and borrowing his wheels and tires and the effort to do a 4 wheel change it is worth the effort to try em.

I will for sure take a picture of the two tires side by side. I will need to do some calculations to see how much the gear ration is changed. It will be an interesting test.

Gorgeous here in CT today, 57F and not a cloud in the sky. Now if our 2 miniature humans could let us sleep we'd be able too enjoy some of this beautiful end of summer season

Good Morning.

Seem to remember a test done by one of the magazines on plus sizing wheels. Going from 15" to 16 17 18 and 19. They were for the most part able to keep the overall diameter of the wheel tire combination the same by going to a lower profile even though with larger rims wider tires were used. Going from 15 to 16 and 16 to 17 .1 second was lost 0-60. But .1G was gained in lateral grip. Going from 17 to 18 the acceration stayed the same and lateral grip still increased .1G. They said it was due to not being able to get the same tire compounds as the smaller rims. Going from 18 to 19 the same .1 second loss and .1G increase. With each .1G increase in lateral grip there is also a slight decrease in slip angle due to the lower profile which should give a crisper steering feel.

Going with lower profile steering should feel a bit more responsive (the increase in lateral Gs), but the ride will be more harsh like you have put on stiffer springs and/or dampers. And yes, acceleration will be a tad slower, but braking should take just a bit more pressure initially to overcome the rolling increased rolling inertia.

No doubt I will be fighting understeer with these wheels. A lot more rubber in the rear will keep that planted. The fronts are the same 205 width but the 17s are still a wider since they are 17s.

I don't have the HP to steer with my right foot except in 1st gear.

You can adjust the apex balance changes due to wider rears with anti-sway bar adjustments. You can help the front initial turn in with a little more aggressive negative camber.

Power oversteer is always a huge challenge HP wise with the 911 with all that weight over the rear wheels. I've found Porsches generally have just enough power to plant the right foot on corner exit without having to worry about power oversteer. And simple or throttle lift oversteer can get out of hand very quickly too. But you should be able to find an apex balance that lets you lift a little to get the fronts to grab a little to turn in the car more, then get immediately back in the throttle before the rears let go. You have to be careful because the lower profile has less slip angle so you can't go as far into the slide before the tires let go.

On my Boxster to get a really sharp turn-in I had to let the clutch out on my down shift as I turned in with the revs a little low so the rears would break to help the car rotate. Since there is more weight in the back, they almost immediately re-grip when adding throttle back in to maintain corner speed.

morning all. well the meds for a bad migraine didn't help at all last night.

I keep my alignment optimized for highway use. I will be driving all the way to Maine & Canada next year. No doubt every single suspension part I can dream up is available for my 911. I will NOT be making a 911 autocross special!

There is a range of recommended settings for camber, castor, toe, etc. You can dial those in at the limits of the setting for best results for autocross type handling without effecting the highway use.That is how I have my 928 set up, at the best handling settings within the factory limits.

And I understand what you are talking about. Even at the stock settings my Boxster was so twitchy at high speeds It was not what I considered safely driveable above 120mph..It was happiest at about 90.

the joys of parenting.......we found out last night that a friend of my son decided its not worth it anymore and committed suicide. I had a friend do that in high school over a girl and I remember thinking he was stupid. I hope Connor can get past this with ease.

Glen before you buy 16s make sure there are tires available. I don't recall seeing just a ton. I'm in the same boat as you. Need a good tire and there just aren't any in 15" these days. Luckily living in AZ I can run summer tires year round.

Hope they figure out the cause.
