I have a set of Hawkeye WRX seats fitted to my Blobeye and i'm looking to lower the seats a bit or atleast the driver's side.

Before I go and consider a set of aftermarket seats I was wondering what OEM fitting options are out there? I've seen this option from JapanParts.com but wasn't sure if this would fit my seat as it specifies non-recaro STI seats:

But also this only lowers the seat by 15mm and I feel those won't be a particularly dramatic change.
If anyone has any good alternatives or has a set of Corbeau seats fitted i'd also like to hear how they are as that would be my choice for aftermarket seats

 

I would also like some information on the above, I find my STi seats in my Blob are way too high.
