Will these RB320 springs part numbers front...LE/07/D5/001and rear.... LE/07/D5/002 colour of springs black. Would these fit a blobeye 2003 STi? Thanks.

No RB320 springs have a Classic rear Spring seat.

If your after a springs speak to Peter Cambridge. He can supply spring kits for all types of Impreza. Kits come with springs the correct bumpstops and revised geo settings.

The fronts will fit but the rears are slightly too large a diameter for the 03 shocks.

What you could look at doing is sourcing a set of Prodrive Red 05+ springs or just the Red rears. These are exactly the same spring rate as the RB320 items but are the right diameter for the 03. You can then marry them with RB320 front springs to achieve the same setup as the RB320, including a front rake which makes a good difference.

The Prodrive Red 05+ fronts have the same spring rate as the RB320 fronts but are longer so you do not get the rake.
