zooted Posted February 15, 2005 Share Posted February 15, 2005 When I really accelerate, the back end of my Leg GT feels that it drops as the nose raises up a bit. this is from a running start and from a stop. I have AP stage 1. Which factors/upgrades affect this aspect of handling such as tire pressure, shocks, springs, etc? I have no experience or knowledge on suspension other than firming up my TR7. I would like the car to be flatter both in corners as well as on acceleration on the flat. z Link to comment Share on other sites More sharing options...
scubie02 Posted February 15, 2005 Share Posted February 15, 2005 stiffer springs and shocks, beefier anti-sway bar for the cornering part, tires with stiffer sidewalls... Link to comment Share on other sites More sharing options...

kanoswrx Posted February 15, 2005 Share Posted February 15, 2005 I got the JDM GT Bilstein struts and springs and that helped get rid of the dips and dives when accelerating and braking. Sway bars will only help in cornering. Link to comment Share on other sites More sharing options...

rc0032 Posted February 15, 2005 Share Posted February 15, 2005 how much did those set you back, and where did you get them, if you don't mind my asking...? Im running JDM GT struts with Pinks. I got the JDM takeoffs from SC GT. Great guy to deal with!! Link to comment Share on other sites More sharing options...
kanoswrx Posted February 15, 2005 Share Posted February 15, 2005 I got the suspension from JDMPartsTX.com cost me 700 so pretty cheap I think. One day I might do what rclark0032 did and put pink springs on them to get the lowered look. Link to comment Share on other sites More sharing options...
lisn2me2 Posted February 16, 2005 Share Posted February 16, 2005 look at www.avoturboworld.com buy engine mounts, tranny mount, pitch stopper nigh and day and does not affect drivability!!!!!!!!! Link to comment Share on other sites More sharing options...
Jaxx Posted February 16, 2005 Share Posted February 16, 2005 uh.... notsomuch help on the porposing its the soft springs i have noticed it too nose lift on acell nose dive under brake springs springs springs .. and struts sway will have no affect (on this proublem) still a good upgrade engine/tranny mounts will have no affect (on this proublem) -questionable upgrade depends on your direction for the car IBKEEFE Link to comment Share on other sites More sharing options...
scubie02 Posted February 17, 2005 Share Posted February 17, 2005 "I would like the car to be flatter both in corners as well as on acceleration on the flat." he said he was looking for help both in acceleration and stopping but also in the corners--the sway's would help with the cornering, and the springs and struts/shocks whatever it has will help with both Link to comment Share on other sites More sharing options...

SBT Posted February 18, 2005 Share Posted February 18, 2005 I know that there was an Anti-Lift Kit (ALK) for the 2nd/3rd gen Legacys and the WRX, that added both some positive camber at the front and helped to control the porpoising you mention. Have not seen anything like that for the 4th gen (2005) Legacy, so IMO, it's going to take the appropriate spring/strut combination to eliminate this characteristic.

Sands Posted February 21, 2005 Share Posted February 21, 2005 What would the most cost effective/first step to improve the fore/aft stability of the car? z Might be a stupid suggestion, but what tire pressures are you running? Adding 5psi or so can stiffen them up remarkably. If you want cheep, I'd start with that. This is kindof unusual as a problem. Are you getting on the gas smoothly and progressively? (notice, that I didn't say slow...) You may have a bad strut or something. Link to comment Share on other sites More sharing options...
Gohmer1 Posted April 18, 2005 Share Posted April 18, 2005 I used to have a whiteline ALK for my RS. GREAT investment. If they make one for the Legacy, I'm on it. Garret Link to comment Share on other sites More sharing options...
scans007 Posted April 19, 2005 Share Posted April 19, 2005 My sways and endlinks helped a ton with porpousing. I couldn't believe it, sphix can attest. We drove my car (sways and AP stage1) then his (stock) I felt like I was do'n pop-a-wheelies in his car......GROSS......now sways aren't designed for stop'n this but they sure as hell help. So much so that I have yet to get springs, and am waiting for the perfect set (prob coilovers) If you want most overall improvement, I say front an rear sways will get you the most improvement for you buck......all IMHO of course =) Link to comment Share on other sites More sharing options...

CRAZY KEN Posted April 23, 2005 Share Posted April 23, 2005 ALK is the answer you seek!!! Whiteline Anti-Lift Castor Kit Race [KCA319M] $139.00 http://www.renickmotorsports.com/oscommerce/catalog/images/_large/KCA319M.jpg Whiteline Anti-Lift Castor Kit Standard [KCA319A] $159.00 http://www.renickmotorsports.com/oscommerce/catalog/images/_large/KCA319A.jpg This kit is designed to add 0.5 degrees static caster to both front wheels while introducing a substantial amount of front anti-lift. The low compliance bushing will also maintain higher dynamic positive caster. By changing the front control arm geometry, the new alloy mounts oppose front lift under acceleration. This leads to superior traction under power including cornering, dramatically reducing understeer & front wheel spin. The additional castor serves to dramatically sharpen initial turn-in response, then forcing more consistent alignment angles through the corner due to the reduced bushing compliance. The vehicle may require minor front toe settings after fitting. Impreza, Legacy & Forester. Available NOW from Whiteline I know EXACTLY what you are refering to and the ALK by whiteline that I had on my prevoious Legacy was AWESOME. I'm getting defintely getting these babys!!!

91SS05GT Posted April 27, 2005 Share Posted April 27, 2005 Anyone in the NW can look into ipdusa.com(www.subysolutions.com) they have gotten with rallitech(SP?)(both in Portland, OR) and put there sway bars and GP moto COs on a couple of 05s, everyone has love the results both in flattening the turns and isolating the squat and dive. I talked with Chris Delano, real sharp and helpful. Link to comment Share on other sites More sharing options...
inthedeck Posted June 16, 2005 Share Posted June 16, 2005 Definately the ALK. Subietonic said it right on the money...and all the others that mentioned the ALK. Hope they make them for the 2K5 GT. Checked the link provided above (thanks to the provider)...but those look like the ones for the Impreza line...as in, I wonder if those really fit a 2K5 GT? Anyone know for sure?

apexjapan Posted June 16, 2005 Share Posted June 16, 2005 Um, guys - that ALK does not fit your Legacy. Take a look underneath - that part is different on the Legacy bl/bp. That will only fit the older Legacy models. To be honest, it will not help as much, either. Subaru changed that area on the Legacy already, and to a large extent, it is already built in. The dive/squat syndrome is purely because of the soft springs/dampers that you have as standard on the Legacy GT in the states. And if you have enough power, even upgrading to the JDM Bilsteins and upgraded springs won't stop the squat under acceleration.

inthedeck Posted June 16, 2005 Share Posted June 16, 2005 Thanks Paul for confirming my suspicion that the kit pictured is not for the 2K5 GT, and that Subaru already built that into the car. Looks like coilovers or other suspension bits might be the way to go. Later, i. Link to comment Share on other sites More sharing options...
apexjapan2 Posted June 16, 2005 Share Posted June 16, 2005 Yeah - unless the USDM uses the old style front lower arm, the ALK will be a quick resale or paper weight The extra caster already in the front end of the new shape is, as Paul rightly says, lots more than the older cars. There are fewer short cut mod options on this era because it is fundamentally a better thought through set up. Link to comment Share on other sites More sharing options...
