The Sparco sub-frame for the Subaru Impreza WRX and STi (part 00499096) fits Impreza models from 2001 to 2007, covering the GD/GG generation. That includes the peak WRX and STi variants most commonly used for stage rally, sprint, and tarmac circuit use.
The frames provide the 345mm x 271mm base mount bolt pattern, compatible with Sparco, OMP, and Corbeau base mount seats. They are handed, meaning driver and passenger frames are separate parts. Sparco’s sliding runner kit is recommended if fore-aft adjustment is required. Construction is steel. Sold individually.
The Impreza is one of the few road cars where sport seats are likely to go in on both sides at once, particularly in rally builds where the co-driver also needs lateral support. If that is your build, factor in two frames and the sided requirement before ordering.
One practical point: the 2001 to 2007 Impreza commonly arrives with repaired or corroded floor sections from prior use. Verify the factory floor mounting points are sound before fitting, as sub-frame installation on a compromised floor will need preparatory work regardless of which frame is used.
At £82.50, the Impreza sub-frame is priced in the mid range for handed, vehicle-specific fitting hardware. It covers a long production run of one of the most commonly modified sport platforms in UK club motorsport.
Have you written anything about this exact product?
Yes, we have covered this exact product: Top 5 reclining seat choices for your Subaru Impreza WRX/STI, including our fitting guide. That is first-hand coverage from our own builds and showroom, not brochure copy.
Will this fit my car?
This frame is made for the Subaru Impreza WRX/STI. Chassis code and years matter more than the badge, as floor pans change between generations, so if your car sits near a changeover year, send us the registration and we will confirm before you order.
Which seats does it take?
It takes seats drilled 345mm x 271mm (the Sparco and OMP seat pattern). The Compatible seats tab above lists what bolts straight on. If your seat is not listed, tell us what you run and we will confirm the fit.
Do I keep fore-and-aft adjustment?
Only with a sliding runner between the frame and the seat, which is a separate part on Sparco frames. If more than one person drives the car, budget for the runner. Our guide to sliding runners explains the options and widths.
Base mount or side mount, and does it matter?
This is a base-mount frame: the seat bolts down through its base, the simpler stack that suits seats with a flat bottom and keeps the install low-fuss. Our guide on base mount versus side mount explains the whole fitting stack.
Is this for the driver or passenger side?
Both sides are available on this listing, pick driver or passenger side at the point of order (sides listed are for right-hand-drive cars). Left-hand-drive car? Ask us, as the sides swap over and availability varies by model.
