>be interesting to see if you can get those rebuilt, where the camber control arm bolts to the body its a spherical bearing, so unless its worn, going to a poly bush will likely be worse for handling, could be negligible though.

where the banana arm meets the body it in theory should be the same as the macstrut, so the polybush might be compatible, the only thing i'd watch is that the superstrut go's through a little more range of motion, it shouldn't be an issue though, I'm sure I've heard of people doing this and it being an improvement on the st205


When Edophus referes to a spherical bearing does he mean this?? :



So the McPherson Control arm has a bushing in place and the superstrut lower control arm has a spherical bearing in the LOWER ARM #1 (the one with 2 ball joints and a spherical bearing), because the lower control arm on the superstrut design moves more due to it being a more well designed suspension like the double wishbone suspension??

The bearing on the superstrut lower control arm where it mounts to the body is very different to the mcpherson strut bushing here, on the ss lower control arm once the arm is cast, they machine the end that joins to the body, it forms one half of the spherical bearing, so its actually machined from the control arm, the centre of the bearing is then put into the arm, and the other half of the bearing then pressed in. The bearing isnt a seperate peice and cant be swapped or replaced once its done the arms only fit for the bin. The banana arm bushing you could replace, i beleive some people in the uk have done that.

Those roll centre adjusters look good, It aint going to cure the downsides of mcpherson struts but should help correct the geometry after lowering, that must be mega low to need them though!!

I can honestly say from experience that it will not hold for very long, my end links were bent from the pressure and the car was sitting for the most part so I switched them out for the supperstrut setup, the enlinks are longer and the swaybar is positioned diferently

edophos my cars not to low, but we all know that with macpherson even lowering 1.5" the control arms start to point upwards and the geometry is off. as for handling for a macpherson its pretty good, im able to keep up with s2000 and sti's in the corner and they are experienced drivers too, its just i lack corner exit traction from lack of an lsd. my bumpsteer has been measured and corrected to move no more than .006" from static to full compress.

sorry that was off topic a little, but how do you guys think the toyota superstrut is compared to fords revoknuckle? fords system seems to be very simple with less pivoting points. seems like their focus was to fix SAI, which seems like a good thing cause less SAI paired with an ideal scrub radius will work really well together to manage torque steer and making your geometry changes count. this is somthing that is harder to do on a macpherson setup since SAI can move your scrub radius to a good or bad position, but the strut mount being so high up seems to be limited, due to the physical restraints of the wheel and strut touching each other.

the one difference i see on toyota's superstrut is the swing arm. the way its mounted makes it seem like it could very well be like an upper control arm just mounted in a funky fashion, but i could be wrong, it could be just so the lower control arm could move without binding.

yo dude check out page 7 of this thread about the discussion on fords revoknuckle

also check out this thread for how to better improve mcpherson setup http://www.6gc.net/forums/index.php?showtopic=80081. I'm sure you can find much more info for 7th gen and 2002-2006 rsx since they both came with mcpherson up front. i guess this is the right area to talk about it??? they are some other thread's i've revived in the suspension/handling subforum

lets keep this thread superstrut only talk here go to this section if you want to talk on how to improve mcpherson :

check out from time frame 9:15-11:00 minutes they keep on talking about it and even do the comparison between mcpherson corolla and superstrut corolla. So yea

Thats the normal suspension, see its got a solid lower control arm. The superstrut has two pivoting bars for lower control arms. There is plenty of stuff to read on this website if you check out the stickys- Sticky:The Suspension, Handling, Braking thread. <one subforum for example

you obviously had custom end links when you used mcpherson sway bar with superstrut suspension right??

so since you said it was too much pressure. This would cut that pressure in half. if you cut the original tab on the and mount it parallel just like the rear so that the sway bar but move a bit more freely. cause this sounds like a good idea to me






A little late on this but again just use the gt4 sway bar AND endlinks and theres NO NEED to cut, weld, fabricate bla bla bla.
To swap over ull need the gt4:
-knuckles
-control arms
-endlinks
-rotors (brake disc)
-caliper
-swaybar
-struts (shock and spring)

Am pretty sure thats it and its all plug n play i dnt have a shop so i can say i didnt fabricate or weld anything"]
McPherson front sway bar will not work on Super strut suspension

i don't have gt4/ss3 sway bar and endlinks. unless you wanna ship them over for me and i'll only pay for shipping.

Lol you cant use the GT sway bar on the SS suspension. The GT lower control arm is in a fixed position relative to horizontal travel, in otherwords it only swings up and down not left and right. The SS lower control arms(or bars, 2 per wheel) pivot to allow the steering to turn.
If you attach a GT swaybar to the GT4 SS suspension you will be unable to turn the steering and the car will only travel in a straight line. Hence why its attached to the strut not the control arm.

Sorry, sometimes its hard to properly explain things in the reply box. The point I was making is that you cant weld the GT lower control arm sway-bar-bracket onto the superstrut suspension, because the SS suspension's travel not only goes up and down but left and right as well when you turn. The SS has the sway bar mounted to the strut because it doesnt pivot along a horizontal plane as much; in addition the SS has a longer end link to account for the remainder of the horizontal swing of the SS suspension when turning.

^^at least thats what I deduce from the information on this forum and thread.

>>since ford/gm uses a superstrut near identical system on their newer vehicles here's a diagram and explanation as to pros over mcpherson
>
>


Splitting the steering and suspension functions does wonders for front-end geometry. The steering axis (an imaginary line around which the knuckle pivots) is more vertically oriented and located closer to the tire’s centerline. This shortens the effective spindle length and moves the center of the tire contact patch nearer to the intersection of the steering axis and the ground, yielding a significantly smaller scrub radius [see diagram]. Since a long spindle and a large scrub radius are key contributors to torque steer, any reduction of these dimensions benefits steering feel and directional stability.

Another benefit is significantly reduced camber change (the tilt of the tire away from a vertical orientation) as the car is steered off-center. Keeping the tire more perpendicular to the road during turning is a boon to handling.

I have these here and going to fit them to one of my st205s in the morning the other one I have is converted to McPherson so hope to do a comparison test afterwords
I was in the very workshop these were made while travelling Europe this summer and the lads who did them are great lads and very professional I was very happy with them and with the price they are selling for I can see the McPherson conversions become less common over here. their poly bushings they use are harder than OEM but not rock solid they are perfect in my opinion as they improve the handling without making it too hard that it is undriveable.
Does anyone know Cusco lower arm bar ver.II fit to st202 superstrut?

Cusco official site show that ver.II only fit with st205.
all 94-99 celica use same front subframe geometry. Meaning super strut suspension bolts on either RHD or LHD subframes

superstrut and McPherson subframes are different
superstrut: 51201-20310
McPherson: 51201-20300

the only difference I am aware of is the steering rack brackets are located differently, the subframe share the same chassis mounting points so as its a lower bar id reckon it will fit as it would most likely work of these mounting points but the subframes are not identical.
ok thats what i meant to say. read thru the thread and you can see i already posted that a while back ago.

quick question guys.
Can I interchange ss3 superstrut and gt4 superstrut parts? if yes, which ones?

Thanks

Ss2, ss3 and gt4 supertruts setups are all the same. Only difference is the springrate on the gt4 due to extra weight from the drivetrain. Obviously the steeringrack is different on rhd/lhd cars

In case you will buy used super strut parts. I recommend you to avoid GT4. Almost GT4's figure8 were worn out.
