Super Pro Alloy Front Lower Control Arm w/ DuroBall Kit

QUESTIONS & ANSWERS

• Q: What's the difference?  Nick Q.2 years ago

  Looking at these lower control arms (ALOY0014k) and the identical control arms with part number ALOY0015k, the only difference i see in the description is that this one fits WRX only but the other one fits STI and WRX. What's different between the two that makes that the case?

    A:  The ALOY0014K and the ALOY0015K fit the same range of vehicles. Both fit the 2008-2014 WRX and STI. The arms themselves are identical between the two kits. The difference is the larger rearward bushing/DuroBall assembly. On the ALOY0014K not additional positive caster is provided by the orientation of the rear bushing, On the ALOY0015K the rear bushing assemblies are offset from center providing additional positive caster. We offer two versions so they can offer a more ideal outcome across a wider range of setups. Most often we would recommend the ALOY0015K. The ALOY0014K came about later as a number of customers were running an aggressive wheel and tire setup and gaining caster from an upper strut mount (camber/caster plate). Additional caster from BOTH the control arm bushing orientation AND the upper strut mount combined with a wider wheel/tire and/or more aggressive wheel offset (numerically lower) could push the hub forward in the wheel well enough where in some setups the tire would run on the inner fender liner at - or near - full steering lock - typically when pulling in or out of a tight parking or garage spot. Hopefully the above answers your question. You can also contact the RSD team or us directly ([email protected]) if we can better explain or if we've created any new questions with the above.
