Is your hawk a WRX or STI?
If its a WRX, then KYB catalog shows the same Excel-G or Ultra SR shocks from 2003 blob to 2007 hawk saloons as no widetracks.
1.5, 1.6, 2.0, 2.0 Turbo WRX, 2.5, 2.5 WRX Exc. WRX-STi (1.03 - 12.07)
The only difference seems to be saloon vs wagon - saloon part codes below.
WRX Ultra-SR Front:
324033 L
324032 R
WRX Ultra-SR Rear:
324031 L
324030 R
If its an STI, the KYB catalog still shows the same parts for 2003 blob STI - 2007 hawk STI so they seem to think that the widetrack doesn't affect it?? They list the Gas-a-just monotube dampers for the STIs rather than the standard Excel-G or Ultra SR shocks though.
2.0 Turbo WRX-STi GDB (1.03 - 12.07)
STI Gas-a-just Front:
321003 L
321002 R
STI Gas-a-just Rear:
321005 L
321004 R
