Default Tein Stechs, RCE, Whiteline

So, this is some future planning of mine. This will most likely wait until after I get my stage 2 power fix, but when this time comes I am most likely going for Whiteline 22mm adjustable front and 24mm adjustable rear sways. I would have prefered 27mm in the rear, but I have not found them. Of course, some kartboy endlinks will go hand in hand with them. Anyway, the conflict is now between the Tein Stechs or the RCE springs. I have used Stechs on another car. I was more than satisfied and only paid $124.99 for the whole set! But, I just read a great review on this forum about the RCE springs. I went to their website, but only found other spring brands that they have. Did I miss something? Does anybody know where to find the RCE springs and is there really a whole lot of difference between them and the Stechs? Thanks alot.

get the RCE springs from one of RCE's websites:
www.racecompengineering.com
www.gtworx.com

If they aren't listed on the site, just call them - really friendly people.

RCE springs by far. and on the sway bars, don't have a smaller bar in front. on the subaru's, you want the bars to be the same size, or the front slightly bigger. i would do 27-29 front, 24-26 rear

I have read many differing opinions about that. The Crawford sti in SCC ran the larger 27mm in the rear and the 22s in the front. Like I said, this is a daily driver and if I were to go same size front and rear, it would be smaller like the 22mm or maybe 24mm becuase I wouldn't want a super stiff street car.

S-Techs are junk IMO unless its a show car....

Swaybars, well just get whatever you want, however I believe a big FSB with a slightly smaller RSB is the way to go, granted there are some variables to what decision you should make, but generally I think big FSB and medium RSB is a good idea.

I believe you would find a stock or only slightly larger FSB with a large RSB (anything over the WL 24mm RSB) would be quite oversteery (maybe not make you much faster in autox/lapping terms) then add in RCE springs which have a decent front to rear rate balance = you should have a ton of oversteer.

Personal goals should dicate which way you go so just read around here, this stuff has been discussed A TON!!!

Hope that helps.

Thanks. Yea everything helps. But the RCE spring alone will not cause a ton of oversteer. I read a great review tonight that the car actually felt quite neutral. Just the springs alone will help solve some of the understeer tendencies, but the mixed feedback about the same size sways versus larger front sways are all opinionated. If I did 24mm whitelines front and rear and rce springs, I the car will have oversteer tendecies. But, a ton? I'm not sure about that.

Do the springs first. If you feel you need more roll stiffness, add bars on their soft settings. proceed from their to profit.

I agree with this. Andrew, do you daily drive your sti? I'm debating wether I should go w/ bigger sways, but don't want to sacrifice ride comfort. I had Buddy Club racing spec dampers on my last subaru, and it was my DD .

I beat crawfords lap time at streets of willow by 3 seconds last August with my COBB bars. (as reported in SCC's test)

I dont think any sway bars alone can possibly make an STI oversteer.

sway bars wont make your car stiffer over typical bumps like speedbumps, rolling bumps, or expansion joints, but will with diagonal or side loads such as cornering or going up driveways at an angle.

Nice! What other mods do you have, besides cobb's sways?

I couldn't agree more. I had Cusco 22mm front and 24mm rear up until last night...

I now have the larger whiteline 27-29mm front and slightly smaller rear at 26mm and all I can say is wow.

MUCH and I mean MUCH better.

COBB TBE, AP, pro tune (300whp w/ 95 octane), brake-man front rotors and calipers, stiffer bushings all around, sparco 5pt harness, Nitto NT01s, Cusco strut bars front and back, battery relocated to trunk. I installed Cusco Zero 2Rs since then which really helped a lot.

And most importantly, a GOOD alignment!

Here is the link: http://gtworx.com/catalog/product_in...oducts_id=1338

As all the people have mentioned before the decision between any Tein product and RCE is a no-brainer. TEINS BY FAR!!!!!!!!! lol, just kidding. I would recommend getting the Whiteline 27mm front and 24mm rear. Whiteline DOES make a 27mm rear but is not recommended.

Yeah, but I really dont drive all that much (11-12k miles a year or so)

I dont think swaybars really add that much harshness, they are another way to get roll stiffness without making the car much harsher, granted they have their limitations.

Anyway, one of the big reasons for STi's with big FSB's is the fact that it will help turn-in response and resist our camber curve from going to poop so fast.

I find the balance pretty good the way my car is now.

If you people are really looking to make the car something with only mods I think you are missing some of the point... you have to at some point learn to drive around "problems" IMO - and besides any car will understeer.

Anyway, MY personal top picks for mods if you have autox/lapping/DD use objectives: get a proper alignment, swaybars, springs/upgraded struts.

My opinion for DD cars that rarely see the track or autox, just get what you are comfortable with on the street, and always remeber that besides feel there isnt much of a point about going nuts with mods (IMO) for a DD car that rarely sees the track/autox
