OEM Suspension Upgrade Part Numbers - Group N, STI, Bilstein, etc.

[Createddeleted]

Since I have a spread sheet with a bunch of parts numbers and there has been recent discussion of these parts I figured I would post them. (my website for this stuff really never kicked off an maybe someone will appreciate it.)

From the findings below you can see that the GAZOO Race series 86's use a number of Group N parts from the 2008MY car; which is good news for all of us. I had not seen a cross reference and did some digging.


- The Group N Strut mount is the same for the BRZ as it is/was for all the other models.
-I need to verify if 2011 STI Rear mounts will work for the BRZ, if they are any different, and if they provide a substantial upgrade.


I might continue to update this thread. Please let me know if this needs to be moved. I have also omitted some non suspension, chassis, brakes components to make this thread relevant.

TLDR: Some Group N bushings from the 2008MY work.

Any chance you can post the actual spreadsheet for lazy people to copy&paste the part numbers

[Createddeleted]

I tried to post it as an excel sheet and it didn't work. I also exported it out of excel and vbulletin would not let me use HTML. So until I can figure out how to post stuff in a formatted form, you're out of luck. :/

[Chimera]

Post it as tab delimited text?

Where can you purchase the ra stuff in the us

[NissanGuy]

Nice research!

Do you know what's different between yellow and silver BRZ TS struts?
Thanks.

Thanks.

As far as I know, the Silver's are STI made shocks and the Yellows are Bilstein shocks made specifically for STI. Both have an extended length as compared to the OEM suspension. I believe this is also the reason for two different spring sets.



First post also updated with just text for the people who just ant to copy and paste.

I tried a couple of months ago to order some RA parts from Japan. They are not selling them.

Does anybody know if any of these struts would be a good option with the Swift BRZ springs?

[choi0706]

figure about the 2011 rear sturt mounts?
