Boxster S Track Wheel Question

Hi, I Just Bought a 2006 Boxster S, Nice upgrade from my 99 Boxster. I am now looking for a 2nd set of wheel to put track tire on, I was looking for some used cosmetic damaged 18 inch oem wheel, but they are pretty hard to find. I really don't care about the look, I just want them to be straight and work just like oem ones. I didn't really considered third party wheels, is there any aftermarket brand that worth it? or should I really stick to OEM wheel? By the way, I am not interested in spending more money to get fancy liteweight wheel (in case thats your advice).

Thanks! :)

I have always stuck with the OEM wheels because I know they are quality (made by BBS) and I know they will fit. The fit being really important. It is hard to figure out which of the aftermarket ones will fit properly. With my 986S track car, I looked at a lot of aftermarket wheels, and struggled to find ones of the exact OEM widths and offsets. I was uncomfortable shelling out a bunch of bucks, then mounting tires, only to find they don't fit.

There are some good aftermarket wheels out there at decent prices....OZ, for example. But it is the fit that I have struggled with.

I go the route you have suggested above - buying used OEM wheels without real consideration with the look. (They are, BTW, easy to clean up and repair with some bondo, quality spray paint, patience and elbow grease, if you are so inclined.)

I have found sets at places like LA Porsche Dismantlers, Oklahoma Foreign, Craig's List and here on renntech. (I have 4 1/2 sets of mounted race wheels at the moment - it is remarkable my wife has not kicked me out. :D )

Weight does matter, BTW - unsprung mass is bad for handling. But a lot of the OEM wheels available are pretty light. I use Carrera 5 spoke - light and strong.

Now, there are Porsche knock offs. A lot of people use them, even on the track. The race shop I work with uses them on some race cars, but there will be people on this board that tell you never to use them. I don't know. If you are patient and spend some time looking, you will find what you need on the used market. BUT!! check the price against brand new ones - some folks are asking for too much. See what Sunset and.or Suncoast will sell brand new ones for.

Curious as to why 18's?

I've bought a set of 17" 997 wheels for track work...the rubber is darn sight cheaper!

Honestly, because I tought 18" was the smallest to fit on a 987S. I knew every secret of my 986, but I'm still very new with the 987 .

But also because I had with the car a set of 18" track tire, and I wanted to keep the same handling/feeling as the stock one.

I'm brigning a situation, but very opened to any suggestion because I know alot a peoples passed trough this exactly same question before me :)

Is there advantage/desadvantage going to 17" wheel for the track ?

Stock wheels on 987S are 8x18 and 9x18. what width are those 997 17" ones? I guess I don't want to go narrower, and I guess I can't really go larger.

More choice in 17" wheels and tires - cheaper too. More torque, less straightaway speed.

Ehhh.. I'm not sure about that one, the goal here is to compensate the size of the wheel with the tire profile ratio to get the same outside diameter size. It should not impact acceleration/topspeed. In that case it would effect ground clearance and probably cause suspension issues..

I made sure the rolling radius was the same when I swapped tyres. Those were standard 17's on a UK-spec 987, I just sprayed them black.

For track work, I would have thought smaller wheels are better - if 16's would've fitted over the calipers, I would have used those.
