Killer! We added your photo to our Porsche Flickr gallery, so I'll be sure to add the tire sizes as a reference point for viewers

Will I have to roll the fenders for clearance with SM-10 18x8.5 ET42 and 18x11 ET60 with a 235/40-18 & 315/30-18 tire configuration on a narrow body 911?

There are several factors that contribute to the equation like vehicle ride height, tire brand (not all are created equal) and alignment settings. In some instances adding a touch of negative camber is enough to accommodate 315's, while others require rolling the fenders. Tire compound plays a big role. Even your spring rates can play a role, as we have to account for suspension compression when the car is put through its paces. A street car is not going to see the same forces as a track car hopping berms.

As an example, this Carrera 4 (picture 1) has Falken RT615K's in 235/40-18 / 315/30-18 and he has a generous amount of clearance at his ride height. The 996 track/race car below (picture 2) is running the same rear tire size in a Nitto NT01 r-compound which is known for running wider than a street tire in the same advertised size. This in combination with a lower ride height is going to benefit from a fender roll. You can see the major differences in the shape of the sidewall, and both are mounted to the same 18x11" ET60 SM-10.

Ryan, great info! That definitely helps! Thank you!

Thank you for your interest. I am a big fan of the 964 chassis, however, we did not develop an 18" wheel configuration specifically for that platform. Our first SM-10 Porsche wheel release focused on the most popular Porsche chassis that are found at the race track to ensure we provided our largest audience with solutions. Now that wheels are available for the 996 & 997 9911's, as well all gens of the Cayman/Boxster chassis, we do plan to expand the line. There has been a tremendous amount of momentum behind 964 and 993 chassis over the last 10 years or so, and I would love to provide these owners with a direct solution as well.

With all of that said, after doing some research it looks like we just so happen to have wheel specs that work well on the 964 narrowbody and widebody cars:

964 WB
Front: 18x8.5" ET50
Rear: 18x11" ET60

964 NB
Front: 18x8.5" ET50 - 225/40-18
Rear: 18x9" ET46 - 255/35-18 or 265/35-18

Our community Group Buy ended several weeks ago, but the good news is that we consistently produce our Porsche wheels. They are available through our website or through an Authorized APEX dealer.


Fantastic setup, etchhead. I use the tried and true NT01's myself. Looking forward to seeing your setup once things are sorted!

My pleasure. Let me know if I can assist any further.

Any chance you’ll be doing another GB anytime soon? Just bought a Cayman S and need another set of track wheels. I ran ARC-8 for years on my e46 that I got from a GB a long time ago

Apex Wheels

I owned and tracked many E46 M3's, and i remember you from M3F Congrats on the Cayman acquisition. What gen did you go with?

At this time we do not have a community Group Buy running. We typically offer them in Q1 prior to track/race season so drivers can prepare and save. There are quite a few contributing factors when it comes to the Group Buy calendar, but there may be another round in the second half of the year.

Oh my, these wheels are fantastic- fit is perfect and really cleans up my turbo. So much lighter than twists and PS2s as well

Good lord that looks great, etchhead. Is the car located in the Bay Area?

Appreciate your feedback and great to see another set wrapped in NT01's - ready to be used as intended.
