We are back again, this time with another exclusive offering for the Tesla TMC market!
Allow us to introduce ourselves one again - Many of you on TMC may recognize us from the involvement and role in the aftermarket automotive wheel sector, specifically our offerings such as the #systemspec Volk TE37 Ultra M-Spec 19x9.5 +28 5x114.3 Face-4 Concave for Model 3 + Model Y, TE37 Ultra M-Spec 20x9.5 +22 / 20x10.5 +30 / 20x10 +30 / 20x9.5 +28, as well as limited offerings for other enthusiast platforms that you may have owned previously or currently own, such as the WRX/STI, EVO 8/9/X, R32/R33/R35 GTR, NSX, Civic Type R, FRS/BRZ/GR86, BMW M2/M3/M4, A90/A91 Supra MK5, 350Z/370Z, 996/997/991 GT3, 981/718 Cayman/GT4, Tacoma/4Runner/GX/Land Cruiser/Tundra/Raptor, and more. You may have seen us on your favorite search engine on your quest for the perfect JDM wheel (if you're into that). It's about time we came to TMC again to officially serve the Tesla community. We are authorized in-house stockists of the very products we work with, and work directly with the manufacturer and US distributor to provide availability and stellar service to both our retailer and wholesale clients. We offer fulfillment and will-call services and are headquarted in the San Francisco Bay Area, and serve all 50 states + international territories as well. Most importantly, we are Tesla enthusiasts ourselves and perform much of the R&D and product testing on our own vehicles in-house, while working directly with the manufacturer. Not only do we provide access to special-batch and limited-run sizes and colors (we are the ones that help make these batches possible via high-volume batch-orders and groupbuys), we are the source for hard-to-procure wheel sets in general and can tailor bespoke sets suited for your application based on our years of in-house experience across various platforms.
This thread has been created to share and discuss the technical detail of our latest exclusive offering for the Tesla Model 3 sector, specifically; the TE37 Saga S-Plus in native Tesla fitment - #systemspec 18x9.5 +27 5x114.3 in the highly coveted Face-4 concave, with factory M14 lug pockets.
These are now available directly through us at System Motorsports. This is #systemspec.
Technical details about the #systemspec 18x9.5 +27 5x114.3 sizing:
Enjoy some exclusive first-look photos showcasing Face-4 concavity! This is where the true concavity face profile starts. Face 1, Face 2, and Face 3 on the TE37 Saga S-Plus models all exhibit a relatively "flat" face look to it, and is not too visually appealing. Face-4 boasts a deep profile that highlights and accentuates the curvature of the spokes. We typically find that wheelsets with a Face-4 concave profile tend to hold the best residual value on the secondary market.
