March 2018 updates: Now Taking orders!
949 Racing 6UL, VIA certified 770kg max load rating (10% above industry standard). Highest strength to weight ratio of any Mustang wheel.
$319 19x10 +37 23.8 lbs
$329 19x11 +50 24.7 lbs
$339 19x11 +24 25.6 lbs
$339 19x11.5 +56 24.8 lbs
We are proud to announce the release of our 19" 6UL line. We are small company based in Southern California that has been engineering race specific 15 and 17" designs for the last 12 years. Our 15" line sets the standard for race wheels in that diameter. The tooling we built for the 19's is optimized for the GT350. This means our proprietary 6UL spoke design with perfect brake clearance and best possible strength to weight ratio in A356.2 casting alloy. Not a generic tool design in some factory catalog or cast replica of the carbon GT350R wheel.
Specs for the 19" 6UL
19x10 +37 23.8 lbs
19x11 +50 24.7 lbs
19x11 +24 GT350 Front 25.6 lbs
19x11.5 +56 GT350 Rear 24.5 lbs
Load rating vs mass
These are actual maximum weights, with cap and valves. Wheels average a bit lower. This is at our JWL+10 load rating, which no other wheel on the market is engineered or VIA certified for. That we are in the same raneg or lighter than all other flow formed wheels of the same size/offset at higher load rating shows the inherent strength to weight ratio of the now 12 year old 6UL design. Roughly speaking, adding load rating directly corresponds to wheel mass. For example, take a 10 lb wheel rated for 500kg, increase it's load rating by 10% to 550kg and the weight will become about 11 lb. The takeaway from this is that if the 19" 6UL were engineered to the same lower standard as other flow formed wheels on the market, it would be 10% lighter.
Theoretical weights of standard load rated 19" 6UL (if we engineered to JWL standard instead of 10% higher)
19x10 +37 21.4#
19x11 +50 22.2#
19x11 +24 23#
19x11.5 +56 22.3#
Our goal was a no compromise race wheel. Track wheels get bent, that is a fact of life. The stronger we can make them, the longer your investment will last. We have managed this without compromising brake clearance, stiffness or weight. So yeah, we're pretty proud of these
From the website:
The all new 19" 6UL represents a clean sheet design based on our now iconic 6 U shaped spoke pattern. For the larger 18 & 19" sizes we increased the max load rating 10% over industry standard. We have the only 18 or 19" wheel on the market that is VIA certfied for 10% greater impact, radial fatigue and cornering fatigue load. A few other brands use the standard load rating and simply run the test for more cycles on one criteria, not all three. The 18 and 19 6UL wheels have the greates strength to weight ratio
of any wheel on the market today. This translates to a stiffer wheel which means better steering response and less camber load deflection.
Bead knurling & dual valves
The 18 & 19" 6UL retain the 6UL standard knurled bead and dual valve configuration. The knurled bead helps to keep the newly mounted tire from rotating on the wheel, which can cause an imbalance condition. The second valve is located at 180° is used for purging moisture laden air from dirty tire shop air compressors. This moisture creates large temperature and pressure fluctations under high performance driving conditions which can create handling imbalances and loss of grip. We prefer nitrogem purging when it is available but a dry air source will also work.
Caliper Clearance
All 6UL wheels are designed for a minimum of .120 (3mm) staitic clearance to target brake caliper. On the GT350, we upped that to .200 (5mm). We have seen, particularly on the GT350 Mustang, that some aftermarket wheels have less than .060 (1.5mm) static brake clearance. This is insuffcient to allow proper airflow and gravel debris clearance. Even the stiffest wheels flex under 1G+ cornering loads which can lead to intermittent contact between the bareel and brake system if inadequate clearance is engineered in. The 19" 6UL wheel set for the GT350 has a minimum of 5mm clearance at the caliper and a whopping 10mm in the barrel.
Finishes
949 Racing wheels are currently offered in four painted finishes. We have not decided which finish and size combinations we will make in the first small production run
Beryllium, show in pics here. This is a gray metallic paint with a very slight blue tint. Cool gray.
Tungsten. This is a chrome like painted finish that is dark.
Charcoal is satin black.
Bronze is glossy metallic bronze. To be differentiated with the various matte yellow-brown metallic finishes the wheel industry calls bronze. The matte yellow-brown represent oxidized bronze. Our bronze attemps to mimic the coppery-gold sheen of polished bronze.
Visit our website for images of the other finishes. We won't have pics of the other finishes on the S550 until the next bath of wheels arrives here in June, 2018
Lugs, valves
We offer a billet forged 7075 T-6 alloy lug for the S550. It uses a 21mm socket. The wheels have a lug hole large enough to use an impact socket so no difficulties there. For thos that might question how rugger our lugs are, consider that our race team has been using them for over a decade. We have won several national championships in road race, TT and endurace. Won the Thunderhill 25hrs twice, lap records all over the country. All on these lugs, pounded on and off with impact guns. You're not going to hurt them.
Our alloy valve uses a proprietary high temp core, appropriate for use in a competition environment. We strongly recommend the use of metal valves for track use, whether they are ours or not. We offer our lugs and valves in a few different colors, visit the website for more info. The OEM S550 TPMS sensor is gray, which our gray valve nearly matches.
September 2017:
We are in the CAD phase of development for our 19" 6UL's. The first variants will be 11 & 11.5 for the GT350. Specs for the GT350 wheel will be exact GT350R dimensions and offset. Just after will be 19x10 and 19x11 for the other S550's. Below is an uncolored CAD rendering of the 6UL. It will change a bit before final production but this gives you and idea of what it will look like. We hope to have wheels here by January 2018 or thereabouts. No specs, weights or prices yet. We will update this thread as we get closer to production then start a new thread when the wheels are ready. 18's will be closer to summer 2018.
All 6UL wheels are LP cast a356.32 alloy and flow formed. VIA certified at industry standard loads, 690kg in this case. We are targeting 10% above VIA standards for this wheel, 760kg. That may not seem like much but the few structural engineers that understand fatigue life and duty cycles know that 10% is huge. We build race wheels, plain and simple. Folks use them on the street because they look neat but we live and breathe competition at 949 Racing.
Ball park, $299, 25 lbs. All details TBD
A friend of ours (thanks Alan!) took our 4 lug 17x9" 6UL, scaled it up and photshopped it onto a GT350. His car is Magnetic Gray so I'm not sure why he chose the Avalanche. Anyway, fun to look at and ponder. The hub area on the production wheel will be a bit larger diameter than this 'shop.
