Question Front Sti Springs, Rear WRX Springs?

I have a 2004 WRX sedan, and recently picked up a set of 2005 STI springs. Looking for a minor drop and a bit more aggressive handling. I'm wondering if anyone has tried (or sees an issue with) installing the STI springs on the fronts, and leaving the WRX springs in the rear. Just springs, not struts.

I will soon be replacing all struts (not sure what I'm going with yet) and until then, I thought if I installed the STI springs in the front, it would drop the nose a bit and have a slightly higher spring rate for the corners.

Any insight you have would be awesome, thanks!

I can't think of a reason to not put the rear springs on too. Just put all 4 on and be happy.

Thanks Andy. I'm going to wait for new struts before I put on the rears as well, as there seems to be a small leak from the left rear and I don't want to exacerbate any issue that might be there. Also, would like to see the front end come down a bit.

Well, I may go ahead and try this. Haven't been able to find any info on this specific topic anywhere. If once done, the outcome is terrible, I guess I will throw the STI springs on the rear too.

this doesn't make sense to swap things multiple times.

buy your struts, bolt everyone on - once.

you'll be fine

but you may find the biggest improvement in handling comes from the rear springs , when you do install them

OP don't leave the WRX springs on. It will make your car be even more stubbornly understeery.

Ok guys, thanks for the input. Seeing as how there is already a bias towards stiffer springs in the front, I thought going one step further couldn't hurt, but after getting some input I think I will just wait for the struts and put the STI springs on all corners at once.

I appreciate everyone's input.

Cheers!

yep you're looking at a roughly double front to rear rate ratio. 220ish vs 110ish. bad juju. good springs like RCE's for example have virtually the same spring rate front and rear

unless, like me, you have taken over 100 pounds off the front end and you don't need as much front spring rate

well i took about 300lbs off the entire car

but it's all about matching the front to the rear rate basically. the more even you can get them the better IMO. i'm still on the fence about swapping my rce blacks out for pinks and running a 24mm rear sway instead of a 22. the blacks just seem that little bit too hard for DD.
