Morning all. Was changing the rear brakes on my WRX-S at the weekend there and noticed that my drivers side rear spring has snapped at the bottom. About 2/3rds of the bottom ring has sheared off. Looking to see if anyone has done some suspension upgrades and what options I have. Probably not looking to go down the coilovers route though. Is it worth just changing the spring and leaving the struts or would it be better to get a new strut as well. Car has done 85,000miles. Would I need to do both rears?

always best to replace springs/shocks in pairs....

I would not use lowering springs, I brought a exact same car (WRX-S) on the cheap not long back because it was on some cheap lowering springs, I had to restore the enter suspension because all the bushes where destroyed, wishbone arms, drop link, rear frame bushes, the lot, the only thing savable where the top mounts and dampers.

What you want are the standard Kilen springs or the LESJÖFORS spring, these 2 brands are the exact same company based in sweden, same company has the 2 different trading names throughout different parts of the world, but they are exact the same made by the same people at the same place, when I was shopping around for a full set of spring it was actually cheaper to import the LESJÖFORS springs from abroad that to by under the UK trading name of Kilen.

Another thing, with having the WRX-S, some car part providers are mistaking this for the STI when purchasing parts online, STI springs wont fit your WRX-S, if it fits the STI then it wont fit the WRX-S even if the sellers specs says it does, Eibach springs are been advertised by places like "europarts" and "buycarparts" as compatible with the WRX-S when there not, I know for a fact because I originally purchased the "Eibach Pro" springs set only to discover they dont fit after lifting the car and dropping the dampers ready to change the springs, the springs are 2 short and dont even need to be compressed to go on the damper, what you end up with is a loose spring sitting in your damper doing nothing but shake around loosely, the STI must have different dampers a smaller spring area than the WRX-S there is no way any spring from or compatible with an STI will fit.

 

But anyway the Kilen / LESJÖFORS springs are the way to go, my car drive tons better now it has the OE springs than it did with the lowering spring which did nothing other than wreck the rest of the suspension.
