I'm trying to improve the overall handling/stability of my wrx before i do power mods. Right now i have 17s w/ 225 ES100s and B&G springs. What would be the next logical upgrade..I know a front strut bar doesnt do much..how about a rear?

sway bars and endlinks 22mm but most are adjustable up to 24mm :)

thatll fix ya right up

do strut bars if you want. i did rear w/ shocks & springs so i dont have to keep taking that back seat out. no front yet.

theres also the ladder braces...


but i think the sways will really give ya what you need so start there

thanks for the info..i'll check out that sticky as well.

I'm coming from a Mazdaspeed Protege, which had really good handling for a fwd car..it handled like a go cart in many areas. but i know the wrx is designed differently than that, and would probably edge out the Mazdaspeed on a real road course.
It would just be nice to get back some of that confidence when i throw the wrx into a corner.

Did you get a good alignment after you put your springs on? If not that will help a lot. And I'm not sure what driving style worked best with the Protege but with the wrx, you might want to try slowing your entry speed a bit more and then starting to accelerate sooner. Use that extra grip under acceleration to your advantage.

Yeah, an alignment would probably help, but I dont know if I should get that done at the dealer, or some other shop. The dealer might complain about my aftermarket springs and wonder why i'm getting an alignment w/ only 2500 miles on the car..lol

As for driving tips w/ AWD, I've heard many times that slow in/fast out is better on this car...

What negative side affects would there be to having a sportier alignment? More tire wear? Also, would a good shop know what specs to use to for alignment?...sorry, i'm still a newb w/ this car.

tire wear mainly.

some searches will yield some good target alignment specs. typically, people try to run -1 degree of camber and 0 toe.

you can get an STi replica rear strut bar on ebay for about $19 plus shipping. The sway bar is more effective than the strut bar, but for under $40 its a good deal. There's also a guy selling cusco V2 replicas on ebay...i got one for about $70 including shipping...works great. Also - you might be able to get a 20mm rear sway bar for free if you go to a local Subaru performance shop or a dealer's repair shop if its a shop that does performance upgrades. usually they have so many 20mm they don't know what to do with them all...they usually just throw away the 17's.

i also hear a RUMOR (that means it may or may not be true so don't hold me to it - this is second hand info i'm trying to get verified) that Saab 9-2x FRONT end links will fit WRX's and they're solid metal ones.

Thanks for the continued info..
How difficult is the rear strut bar install. And what is the size of the stock rear swaybar?

on 02-03 sedans the RSB is 20mm. on 02-03 wagons its 17mm

I believe all 04's have 17mm RSB's.

the STi's started out with 20mm, but switched to 17mm sometime between 04 and 05.

so if you go to a shop and ask for take-offs make sure ou get a 20, and make sure YOU have a 17.

rear strut bar is so easy it can be performed by a stunned herring. you might have to make some small cuts in the trunk liner to make it fit (on a wagon). I don't know about the sedan...might involve removing the rear seat, but I hear that's not so hard either.

just don't overtighten the strut bolts...they only need 14.5 ft/lbs

If you keep your toe at 0 you shouldn't have an issue with tire wear. Try to get you rear camber as close to equal from side to side as you can. Its not really adjustable but you can move things around some to adjust it. Use the front camber bolts to get as much negative camber as possible while keeping the camber equal and each side. You'd probably be best off finding out what some good alignment shops are from people who are in your area.

Yeah i have an 04 wrx sedan..so they have a stock 17mm rear swaybar and to help reduce understeer, i need at least a 20mm?

well i have an 02 wagon.

I put in a 20mm take-off RSB, rear strut tower brace, rear solid endlinks, and a cusco V2 replica front underbrace to compensate for some of the OVERSTEER I was developing. Now i'm pretty neutral. on a sedan you may have slightly different dynamics.

a lot of people with 22mm+ RSB's complain (or are intentionally looking for oversteer).

Well I'm just trying to counter the understeer..I dont know if it would be good to get too much oversteer for daily driving. I only plan to autox once in awhile for now since this is still my daily driver..

With just a 22mm Helix RSB and a rear strut tower bar on my wagon, I'm getting a fair amount of oversteer. I may loosen the sway bar one notch and buy a front underbrace so the car is more neutral. Occasionally it feels a bit tail-happy in a fast turn or on ramp. :eek:

Perhaps the cheapest, most effective adjustment available to reduce understeer.
