Hey guys just curious about what the best mods are for helping with the understeer. I am thinking right now i will get a rear cusco 23mm swaybar with nice endlinks.. and i have 225/50/16 toyo proxes 4's... anything else i should look into to defeat understeer?
TIA

Yeah...driving lessons.

Just so you know, a 23mm rear swaybar, without beefing up the front swaybar, will simply cause a really good case of oversteer. Your best bet is going to be something in the 20mm range, which will make the car feel more neutral. You DON'T want your WRX swapping ends, because that leads to posting an "I WRX'ed my WRX" thread, where everyone either flames you or consoles you over the loss of your car.

 

A rear sway bar and some good track school time was all it took for me. But like roo said- its about skills, and you can't beat education, its a whole lot cheaper than learning hard lessons from experience.

It doesn't take a whole lot to neutralize the inherent tendency for understeer, but once you have the car set up neutral, the impetus is on your feet and hands to keep it pointed where you want it.

I'd reccomend an adjustable bar so you have a few different settings to try, these cars are pretty neutral as it is and you don't want to stiffen the back up so much that you get a tendency for snap oversteer either (roo was posting while I was typing myself- so "what he said").

The proxy 4's are pretty good rain tires, but not particularly outstanding in any other regard, but stickier tires only raise the threshold of slipping, so learning to balance the car on them is probably safer than on Michelin Pilot sports or Goodyear Eagle F-1's.

One more thing after re-reading your post- you don't want to kill understeer, because without it you have only oversteer, which can be just as dangerous- you need to be able to manage both of them to be adept at high speed driving.

 

ok so then do the front and rear at the sametime if i do a beefy rear. does the front need endlinks? cause i know the rear has plastic endlinks. but have no idea about the front.
and yeah driving lessons are on my list. i really want to start to track my car at places like infineon and laguna seca etc.. and dont wanna track it unprepared

but thanks for the suggestions. does anyone know of a good front and rear swaybar package?

 

And beefing up both sway bars without tweaking all the rest of the suspension can screw up handling and ride, any of the real experts here will tell you to focus on your skills, the car is already set up pretty well.

 

i would say i am a pretty good driver for never having taken lessons but at the sametime i am sure there are novice moves a trained driver would notice..

 

and lessons are most definitely something i will do this summer or spring. but at the same time id like to have my car upgraded a little bit on handling mods.. (coilovers sways mainly)

 

ignore roo, you don't need to do the front at the same time as well. Just the rear is fine. I suggest getting one of the adjustable rear sways and then you can test out different settings and see what feels/works for you the best.

 

Bad coilovers are going to hurt more than they help, and really good coilovers cost a ton.

If there was a coilover package out there that I knew was great I'd have had them on my car a long time ago- but I'm still on the stock struts and springs now approaching 175,000 miles.

And I hate to be the one to tell you this, but if you never have taken lessons you really should not consider yourself a good driver.

I have many hours behind the wheel with instructors next to me and I still wouldn't claim to be a very good driver.

 

check out the reveiws section. I got an adjustable whiteline rear sway and it's fantastic..perfect balance on the middle setting.

 

I changed out to the whiteline 24mm adjustable, on the middle setting it helped me get rid of the understeer on my wrx. If you have a decent amount of instruction snap oversteers not gonna happen with this size sway bar. I'd also suggest rear mounts.

 

I ran the Perrin rear bar in the middle setting for a long time and it helped a lot. It made the car a lot more neutral. You will be fine with just a rear bar, just don’t have it on the stiffest setting unless you have a front bar also.

 

i totally agree, but trained drivers in my opinion are generally great drivers, but then there are always untrained good drivers, like people having a concept of whats happening when oversteer occurs, and have enough skill to correct it, or anything in the similar.. that kinda stuff can make a good daily driver.


Any suggestions on brands? i really wanted a cusco so i could be like alex
i was thinking cusco actually just because they are a great brand. but i am not sure if they offer adjustable sways. and i was gonna go with pillowball endlinks through Noah at LICmotorsports. Any other suggestions for understeer as far as mods go, i know schooling=best option, but thats not gonna happen until april - june time.
i am thinking for now a rear sway with endlinks is a good step for now.

 

sweet i think i am gonna go with either the perrin or the whiteline, anyone have a preference over the two?

 

You will be fine with a rear sway bar and enlinks, I have Perrin and would recommend that company. A driving school or group 1 track event will not take away understeer, you will just learn how to control it, remember that.
