Anyone familiar with Whiteline part number BSR51Z rear sway bar made for my model such as what does it come with and about how much? Also are there Swift springs available?

 

Any rear sway the fits a WRX will fit that car, youll need WRX endlinks. Swift springs will fit, but they are made for the WRX/STI tophats and dampening, which I doubt the Outback sport can match. Somewhere I read that the tophats are weak on the 08 WRX, 08+ 2.5i models which includes the Outback sport. They changed the top hats, strut, and spring for the WRX in 09 to just STI tophats, higher spring rate and dampening.

 

Ok swaybars are easier to find. On the lookout for good springs now. Thanks.

 

The best IMHO are the JDM Pink Springs. There are two different sets of Pinks, one pair has a lower spring rate, the JDM ones are stiffer.

But, if you want to keep the stock struts, the softer springs are probably safer to run.

 

Are those springs progressive or linear? I prefer linear.

 

Well the Swifts are progressive. Not sure if the pinks are or not, but if you are going by the looks of the springs, the Swifts and Eibach have a couple coils that are closer together.


Not an actual Subie part, just for representation.

But, the pinks and some other brands do NOT have a section of coils that and closer together. This might mean they are linear...not having sections in the spring with different spring rates.

I had Swift STI springs and I didnt like how they rode. They felt softer than stock and they were advertised as stiffer, that was most likely the progressive part.

Warning! I read somewhere the progressive springs give more life to your stock struts. Not confirmed.

 

So the pink springs are slightly stiffer than OEM. But which one. THe 2007 OBS had softer springs and teh newer 2008 has stiffer than 07 OEM springs. So is the new pink springs the same as whats on the 2009 or just less of a difference stiffer than an 09 OEM?

 

NM...f these are going on Impreza non-WRX struts, stick with these pinks..

B2010FG000 Front
B2010FG100 Rear

because your top hats and struts will work well with these, any stiffer (the B2010FG200 and 300) and you may damage stuff.
