Adjustable L Strut Tops on the way .
Posted: Sat Jun 07, 2008 11:41 am
Hi all , I have located a pair of little used Noltec adjustable strut tops for the 90's era Impreza (Pn N44003) and these appear to fit L series struts/towers as well .
My suspension people tell me that the Noltec tops are a little better than the Nolathane ones in design and urethane composition so I lucked out there .
I am hoping that they will have enough adjustment range (together with the packed forward radius rods) to get up around 6-7 degrees of positive caster and a small amount of negative camber like about 1/2 deg .
Ellie still has more front body roll than I like because it still has the std front RX springs and life expired dampers . If I can screw in the above mentioned amount of static positive caster at least the dynamic camber will change to the point of the front tyres at least gripping rather than ploughing down the road like they do now in low traction conditions ie wet roads .
The small amount of static negative camber will just be there for poorly cambered straight roads .
Depending on how much slop the std worn rack and ball joints have I think I'll get it aligned with zero (neutral) toe . The AWD transmission has easily halved the drive loads on the front suspension and therefore the front wheel drive effect (front wheels trying to pull themselves forward - to toe in) is a lot less . Also I'm using urethane radius rod bushes so there is less compliance than std rubber ones have and therefore less toe change .
The rear Koni dampers were supposed to go in last week but the bodies were longer than specified so they are going back to Toperformance to be shortened . As they were there was not going to be enough adjustment range to get it even a tad below std height and the springs were completely unloaded (not trapped) even then .
At the moment Ellie has its butt up in the air because it has wagon springs (196 in/lb instead of normal RX 180 in/lb early or 160 in/lb late rate rear sedan springs) and sedans are a fair bit lighter at the back than an L wagon .
To look at it rear camber is either neutral or close to even at that height so it should go more negative when the ride height is less . I really don't mind that so much ATM as the MY00 16 x 7's in the wings I believe pretty much fill an L's rear arches with 205 50's and that lip really needs to be folded in .
Depending on what the rear toe/camber works out to be we should be able to fiddle mounts to get it close enough .
Have a good feeling about this , cheers A .
