Default Type RA Suspsension Compatibility with 2005 STi

My 2005 STi has started to get a little long in the tooth and is showing some signs of wear and tear. Among it's symptoms the rear struts have begun to clunk and I'm looking at options to replace them. I have a connection that has a set of 2018 Type RA Bilstein struts for sale for half the price of of any other solution I've seen, but I haven't been able to really find any information about compatibility.

I know the 2005 STi suspension isn't compatible with contemporary 2002-2014 WRX suspension with 5x100 bolt pattern, but the 2018 Type RA and the 2005 STi both share 5x114.3 bolt patterns. Additionally side by side the struts look identical to the '05 OEM strut images online.

Does anyone know if these will swap in or if there's a place to get more authoritative information (like specs for the geometry or other factors that would inhibit compatibility)?

I don’t believe they will fit. From owning pretty much all the models you stated and installing multiple struts/coilovers I think there are slight differences.

Have you checked your Bilstein Type RA sound system carefully? [size=1pt]tiny fishing[/size] I think it was sold at a very low price so I think the sound system is really not good. Besides, you need to take care of your car more and it will still work.

Definitely not compatible with anything after 2008. The front will very likely bolt up but the rears will not. Actually I think the front tophats are slightly different as well.
