Tarmac Sportz Nissan 350Z (03-09) Complete Subframe Refresh & Rebuild Kit (Common Rust Issue Solution)

We regularly see Nissan 350Z owners come to us after failed MOTs due to “rusty subframes.”

In most cases, this is a misdiagnosis.

The 350Z subframe is aluminium and does not rust. The corrosion typically comes from the surrounding steel components, most commonly the kidney brackets and the W-brace, named after their distinctive shapes.

To solve this properly and long-term, we’ve put together the Tarmac Sportz Rusty Subframe Refresh Kit.
