An OMP direct fit subframe for the Mazda 3 in 1.6 16V specification, covering cars from 2003 to 2010. Part number HC835.
The engine is part of the fitment here
Read that before you order. This listing is specific to the 1.6 16V. If you have a different engine in the same generation, contact us before ordering and we will confirm rather than let you assume.
In particular, the 2.3 MPS has a different configuration and is not covered by this part number. If yours is an MPS, tell us and we will find you the right frame.
The years span two chassis codes
The BK from 2003 to 2009 and the early BL from 2009, which share enough floor structure for OMP to cover them together. Send us the registration if your car sits near that changeover.
What it is used for
Occasional track day work rather than serious competition. The first generation Mazda 3 is a good chassis with modest power, which makes it a sensible cheap starting point.
What else you need
Side mounts and the seat. Steel, black powder coat, no bolts supplied. Both patterns drilled, 345 by 271mm and 405 by 290mm.
Tell us the seat and we will confirm the combination.
Will this fit my car?
This frame is made for the Mazda 3 1.6 16V. 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) and 405mm x 290mm (the Recaro seat pattern). 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 OMP 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.
