APEX | Porsche Track Wheel Development

UPDATE: Our Group Buy is now live! Please click HERE for all details.




As you might have seen in our recent survey thread, APEX is working with the Porsche community in an effort to produce track wheels that offer unprecedented value. We have received 800+ survey responses from fellow community members offering feedback and fitment requests. The 996 chassis represented approximately 23% of the surveys submitted, so we’d love to hear more from this community. If you haven’t chimed in yet, you can still provide valuable feedback by taking our Porsche wheel survey here.

Before we can move forward, we need to fine tune certain fitment specifications for the 996 chassis. So, we’re seeking your expertise and need detailed feedback on the specs we believe should be produced.

Below is a list of all widths and offsets we’re looking to create for a variety of Porsche chassis in the first round of production. Fitments specific to the 996 chassis can be seen listed below. In accordance with the survey results, these will be produced in 18” sizes first and 19” thereafter. Survey data and community feedback will directly determine what will be produced, and when. Please note that both the SM-10 and EC-7 designs are being reviewed for feasibility. In your comment, please include tire sizes, tire model, and alignment settings if you have a change request so we can track developing trends.

Proposed Wheel Specifications

Front:
18x8.5” ET50
18x8.5” ET42
18x9” ET46
18x9.5” ET42

My 996 4S DD/Street/Track set up is 0.5 Toe Front, 2.5 Toe Rear with 1.4 Camber Front and 2 Camber rear with 235/40/18 & 295/30/18 or 235/35/19 & 295-305/30/19

So I'm okay with 18x8.5 and 18x11 wheels mentioned above

FYI there is no 305/30/18 Tire other than a Hooiser Wets, you should take that off your list to make things simpler

Thank you for sharing! What are your thoughts on the listed offsets? I have omitted that rear tire size. I knew the 305 option would be seldom used, but wanted to include in the off-chance that someone wanted to run that width.

I'm no master of Offsets, my car is super low and I have issues ruining 19x11 ET35 with 305/30/19 and 295/30/19 rubs under full compression with the above Suspension Specs on PSS9's

as for my track set up OEM WB GT3 Wheels 18x8 ET50 and 18x11 ET45 with 235/295 Trofeo's and this is Lovely

Thanks, Zookie! All fantastic info to mull over. I appreciate you providing this detailed insight and sharing your experience.

What are your impressions of the Trofeo R's?

Cheers!

Here we have a rendering showing the 18" SM-10 in our three finishes against a Racing Yellow Cayman GTS. The front wheels are profile 1 concavity - the least amount of concave. The rear wheels are profile 2 concavity - medium amount of concave.

I Use them as my Daily Driving Tires in the Summer

With my Alignment I have managed to get 17,000km on the rear and well over 25,000km on them on Street Driving
Been Using them as my DD Tires since 2013, very confident in the rain with those Trofeo's

Better in the Rain than Cups and r888's

I put about 25-30k a year on my car

With your mildly aggressive alignment, that's an amazing amount of miles for a 60TW tire that comes with 5-6/32nds new. From my experience, R888 can be downright scary in the rain, so it's great to hear that there's another quality dual duty option.

Keep enjoying your car in good health -- which will hopefully be on APEX's come spring!

I hope you all had a joyous holiday season with friends and family.

As we inch closer to production, please continue to share your thoughts here and view our new imagery below!

Here we have a 997 GT3 equipped with APEX SM-10 in our three finishes. The front concavity is profile 1 and rear is profile 3.

Happy new year to you all!

I hope 2018 brings you health, happiness, prosperity... and APEX wheels this spring!

Here we have a beautiful basalt black 996 GT3 on 18" SM-10 in our three finishes. Similarly to the rest, these front wheels are concavity profile 1 (least concave). The rear wheels are concavity profile 2 (medium concave).

To answer the numerous people asking for concavity profile clarification, here’s a general overview of how they’re presented and produced for each specific application.

We offer our Porsche-specific APEX SM-10 and EC-7 in two or three different concavity profiles. Pending design and final engineering/strength optimization, the wheels will vary in concavity depth from profile one to three; one being the least concave, three being the most concave. Typically, the level of concavity is dependent on the width and offset of the wheel. The wider the wheel and lower the offset, the more concave. Whereas the skinnier the wheel and higher the offset, the less concave. While the amount of concavity may differ, some wide(r) and low(er) offset wheel specifications have a deeper “pocket” or center pad where the studs/lug nuts attach to the hub.

The varying concavity profiles in the SM-10 and EC-7 ensure that spoke curvature and brake clearance is never compromised due to width or offset changes in the wheel. The SM-10 and EC-7 are of the few 18" VIA/JWL certified wheels on the market that can clear both an aftermarket and OEM 380mm rotor 6-piston brake kit.




We are now making final tweaks in the engineering phase, prior to launching our initial pre-order/Group Buy next month. We’ll continue to update the community through the different phases of production, and will continue to release on-car photography to give enthusiasts a better idea of how some of these proposed wheel designs visually appear on specific chassis. Stay tuned for updates and solidified ETAs!

Please let me know if you have any further comments, questions, or fitment change requests.

As we progress into the final stages of engineering and initial stages of production, please feel free to reach out with any questions or comments.

Our pre-order group buy is going live in approximately one month. I will update with a solidified date and further details shortly.

Thanks, all!

Thanks to the community, we’ve nearly finalized our proposed 18” wheel specifications. As you may very well know, seemingly minute millimeter differences in wheel offset can result in large differences in overall wheel fitment. It directly determines how the wheel fits, performs, and is often times the deciding factor between it working, working well, or ultimately not working. With this said, we need your assistance in deciding between a range of three millimeters in offset for our 9” front option.

18x9” ET48: least inner (suspension) clearance, more outer (fender) clearance
18x9” ET47: 1mm more inner clearance, 1mm more aggressive towards the fender
18x9” ET46: 2mm more inner clearance, 2mm more aggressive towards the fender
18x9" ET45 or below -

For example, the +48 offset has approximately ~2mm of inner clearance (wheel to bottom spring perch) with linear spring equipped Ohlins coilovers. We’re unsure if this is the case across the board with all linear spring coilovers as it’s dependent on the use of a helper spring, spring length, inner diameter, etc, etc, so we’d like to hear your thoughts. Since it will not require a change in negative camber settings from the original +48, our suspicion is that the +46 is the best option to compensate for any tire deflection under severe load while on track. We typically like to see ~3mm of clearance to ensure ample clearance under any load, condition, or to account for tire deflection.

While a 997 GT3 equipped with cup flares can accommodate our profile 2 concavity wheel specifications in the front, we opted to show what front (profile 1) & rear (profile 3) wheels would typically be seen. Here is some on-car imagery of our partner, BRRacing, 997.2 GT3 on 18" SM-10 in the three available finishes.

Have always appreciated how organized your posts in forums and the quality of the product. Keep it up guys!
If I hadn't scored a set of Rays I'd be all over these.
