SKU 00499070-Ibiza-Mk3 is the steel base-mount sub-frame for the Seat Ibiza Mk3 (6L series), covering the 2002 to 2008 production run. It replaces the standard seat runners and accepts base-mount sport seats using the 345mm x 271mm bolt pattern from Sparco, OMP, or Corbeau.
The base part number 00499070 is shared with the Skoda Fabia Mk1 and Volkswagen Golf Mk6 sub-frames, which reflects the mechanical similarities between those Volkswagen-group platforms. The car-specific suffix tells them apart at the stock level.
The product notes that this sub-frame requires Sparco sliding runners as part of the installation. The runners (0049306 single, SS0049302-X2 pair) sit between the frame and the seat to allow fore-aft adjustment. Factor them into the build budget alongside the sub-frame itself.
Both driver and passenger sided versions are listed for RHD cars. This listing covers one sub-frame. Order two for a full car fit, one per side.
The Ibiza Mk3 has a small cockpit, and that puts some seat shells out. The R100’s narrow bolster profile is a natural fit here, as it is in other compact Spanish and French hot hatches of this era. A seat with aggressive side bolsters may clear on the initial fit but then foul the door card once a driver is seated; measuring the widest point of the shell against the available cockpit space before ordering the seat is a worthwhile step.
At £82.50, this is priced the same as the Skoda Fabia Mk1 version that shares the same 00499070 base frame.
