Ventura Drag S155 Rotary Forged front runner wheel in Gloss Black with Milled Spoke Windows and Diamond Lip, built for the 5x114.3mm (5x4.5 in.) bolt pattern covering the FoxBody Mustang through S550 Mustang continuum, as well as the Nissan 350Z\/370Z and Toyota Supra MK4. It is the Ventura S155 counterpart to the Laguna S152 S1527C067N21 front runner - sharing the identical 17x5 \/ -21mm \/ 2.18 in. BS \/ 78.1mm bore specification, load rating, and SFI certifications, but presenting Weld's distinct Ventura split-spoke design rather than the Laguna mesh-spoke profile. For builders choosing between the two, the decision is entirely aesthetic - both deliver the same front runner drag wheel performance geometry and construction on these platforms.\u003c\/p\u003e\u003cp\u003e At 17x5 in. and just 17 lbs (consistent with S155 construction at this size), this wheel removes a significant quantity of rotating and unsprung mass from the front axle - the modification that produces the largest proportional improvement in drag strip weight transfer, 60-foot times, and elapsed times relative to almost any other hardware swap on a front-engine, rear-wheel-drive drag car. The Rotary Forging (Flow Forming) process densifies the aluminum barrel for near-forged wall strength, while the inner and outer barrel knurling mechanically interlocks with the tire bead under the sudden load spikes of hard drag launches, improving bead retention without the weight or maintenance overhead of a full beadlock assembly. SFI 15.1 and 15.2 certification makes this wheel legal at sanctioned drag racing events.\u003c\/p\u003e\u003cp\u003e Important notes: this wheel will not clear 6-piston Brembo or larger front calipers - the Shelby GT350 (all S550 years) and 2020+ Shelby GT500 are specifically excluded. All other S550 Mustang trims, all S197 Mustangs, all SN95\/New Edge Mustangs, FoxBody Mustangs, Nissan 350Z\/370Z, and Toyota Supra MK4 are confirmed compatible front-position fits. Hub-centric rings may be required. Requires 60-degree conical seat lug nuts - factory lug nuts are not compatible. Sold as a single wheel.
