Being that the Z31 and S12 share many components of the same rear suspension setup, thought I'd post these up here for you guys.
In the quest for moar low, we've been able to develop and produce a coilover adapter kit for the Z31, allowing the Z guys to run Stance S13 rubber isolator-style coilovers.
Although the upper plates are different for the S12, the lower adapters that allow for the coilover to bolt up for both cars.
These come in 2 pairs (one for each side) and made of aluminum and anodized black.
We are selling them for 59.99, with free shipping anywhere in the US!
They can be purchased at our website -
