Our Rear Under Spoiler Extension is an accessory piece suitable only for our VA WRX/STI Rear Under Spoiler

Full movement can be seen in the video above. Once the desired position is set, tighten and you're ready to go.

Tell me about ABS plastic!

Please note that although all our precision-made ABS accessories are extremely strong and durable, they do not hold the same shatterproof label as our 10mm thick polyethylene composite splitters. The accessories are manufactured in ABS with the intention that they will be lighter, bolt-on attachments that will improve aesthetics and are easily replaceable if they become damaged from varying road conditions.
