Jeph, what is the speed rating of your new tires?

The LED brake light looks nice! Thanks for pointing this out.

You should have your bumperettes painted to match your exterior color, IMHO.

10" in the rear with no spacers? That's a first.

For those of you who are interested Road and Track did a very interesting tire shoot out in the last issue. There were a few inexpensive tires that did very well.
And some more expensive Continentals and Goodyears that perforwed in the wet signficantly better than the rest.
I still have my Toyo RA-1's on the car and snow is predicted tonight! Not sure to go for full snows or a winter tire. Nothing worse than driving somewhere when its only raining and then having to drive home in slush while the Boxsters spins out of control.

According to FedEx shipping, the fronts are 23lbs. and rears 26lbs. I'm not sure if they're aluminium or not. They're made in Italy, which I feel more comfortable with opposed to China or Korea, etc.

Speed rating on the TireRack website said "YR" but the tires say "ZR" like in the following (awesome) picture:

I went to the dealership this weekend (Boardwalk Porsche/Audi - Plano, TX). They're nice there (No charge! $). The were able to get my locking lugs on the rear tires -no special tools required. They even zip-tied my parking brake lines (even though they said the gap [distance from the wheel to the brake line] was fine).

These replicas must be pretty accurate... both the service advisor & the technician were suprised these weren't Porsche wheels!

Also, as per RandallNeighbour's request, 100+ runs did not reveal any steering wheel shaking. And the only time I've noticed the ride to be more rough (so far) when compared to 17" wheels is going over bumps and potholes that suck with any sized wheel.

And speeking of speed runs, does a speedometer need to be recalibrated when different sized wheels are used? My speedometer(s) seem/feel inaccurate.

Jeph, your speedometer show's you going slowing than it actually feels like it...right?

I have 18X10 rears with no spacers as well. They fit fine. Shift26 has 19X10.5 on his. All depends on the wheels. I am even running a 285/30/18 rears with no problems

eBay is great because anyone in the world can see your wheels for sale. I highly recommend that you deal with users from Canada and the US only,others seen really flaky.

Yeah I forgot these look like Porsche factory wheels on the outside but they are totaly different on the inside.

Somebody who knows really needs to answer the question about speedo changes when one goes from 17's to 18's. I want to go from 17's to 18's and would like to know if my speedo will need recalibration.

Logically, if the circumference of the 18 inch tire and the overall height of the mounted tire are the same, the speedo should be accurate.

Perfectlap · 12-13-2005, 11:02 AM

I have had many cars and many sets of wheels changed. Never needed to reset the speedometer for those lesser cars.

Jeph · 12-28-2005, 10:28 AM

My old wheels found a new home. Have you ever wondered what happens to the stuff you sell on eBay? I made sure my buyer sent me pix.

Hmm, that reminds me, I need to update my signature image.

He'll be selling his old rims (below), if any of you are interested, let me know and I'll put you in touch with him. I'll post his auction link soon. He said 18s on his 968 were too rough of a ride.

You go to a lower profile tire with the larger diameter wheel to offset the increase so no speedo recalibration is needed. Overall wheel plus tire diameter remain the same. Likewise you maintain your final drive ratio.

Everyone needs this tool. Tire and Wheel Calculator. It's simple to use and I think it will answer your questions.
