BlownCorona Posted August 1, 2010 Share Posted August 1, 2010 So i have just found out about a part called the Torsion Bar in the suspension and apparently they are height adjustable. From what i can tell its used in suspension designs that have two wishbones. My corona (rt84 1971) has this style in the front but i cannot locate a torsion bar ive looked all over the internet but cannot find all that much information on this subject. My question. Do i have a torsion bar and if i do where on earth does it hide? Thanks p.s. i did a search on OS but if i missed a thread where this has been answered could you please link me?

eke_zetec_RWD Posted August 1, 2010 Share Posted August 1, 2010 can you see a coil spring in the front? Quote Link to comment Share on other sites More sharing options...
Hemi Posted August 1, 2010 Share Posted August 1, 2010 double wishbone setups can have springs too , they go between the two wishbones . if you have torsion bars they usually ruin along the chassis rails back from the bottom wishbone Quote Link to comment Share on other sites More sharing options...
johnnyfive Posted August 1, 2010 Share Posted August 1, 2010 ^ +1 I have no idea what the suspension setup is like on your car, but if you have double wishbone and torsion bar, the torsion bar will most likely run parallel to your chassis rails and the adjuster will be at the end of the torsion bar. Have a look under the guards around your front wheels and see if you can see any coil springs something a little like this If theres no springs there you may just have torsion bars. Take a picture.

BlownCorona Posted August 1, 2010 Author Share Posted August 1, 2010 ahh yes i see. i have coils and shocks + double wishbones. definatly nothing going back to the chassis rail. so no torsions bars. thanks for all your help Quote Link to comment Share on other sites More sharing options...
Testament Posted August 1, 2010 Share Posted August 1, 2010 just for more confusion double wishbone spring on the bottom arm rather than the top and what the british thought was a good idea...... Quote Link to comment Share on other sites More sharing options...

Yowzer Posted August 1, 2010 Share Posted August 1, 2010 This is what the Corona rocks in the front Standard leaf on live axle in back. Easy enough to lower, shorter springs for the front + blocks / reset leaves in back. Sorted. Quote Link to comment Share on other sites More sharing options...
Hemi Posted August 1, 2010 Share Posted August 1, 2010 if your really keen you can get dropped spindles but i think there is a little bit involved in that Quote Link to comment Share on other sites More sharing options...
Testament Posted August 1, 2010 Share Posted August 1, 2010 if your really keen you can get dropped spindles but i think there is a little bit involved in that certs etc. the main issue with putting really low springs on double wishbone setups with the bottom arm starts to point up from the chassis to the hub and handling geomettry goes out the window bumpsteer etc. can become rampant. but it will depend on the angle of the arm to start with and the specific design as to how low before it gets bad/maybe the handling was crap to start with anyway so it won't make much difference.

Yowzer Posted August 1, 2010 Share Posted August 1, 2010 They run a very similar setup to the Crowns which seem to be more than happy with mega slam, so they shouldn't be too bad. Guess ya don't know 'till ya try it though Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted August 4, 2010 Author Share Posted August 4, 2010 that British setup looks scary haha and yup its got 2" lowering blocks in the rear, and its lowered about 2.5" in the front as well with shorter springs i think (guy before me did it) its all captive and handles really nicely, but i want to lower the rear by about 2.5-3" more and the front by about about 0.5". i was looking at how the front suspension is set up and i noticed how the strut is bolted to the lower wishbone. is there any reason why a getting a couple nice strong longer bolts and putting .5" worth of washers between the struts bracket and the wishbone should not be done?

Brock-Lee Posted August 4, 2010 Share Posted August 4, 2010 yes, because its retarded. lower your car like everyone else, shorter springs and shocks and reset leaves and blocks for the rear EDIT: Also, that will do nothing. it will just push the lower wish bone closer to the ground, it might help correct the LCA angles, but wont lower the car Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted August 5, 2010 Author Share Posted August 5, 2010 Its got shorter springs, and i plan on reseting the leaves in the back, All i wanted to do was lower the front slightly more, the strut bolts UNDER the wishbone so it will definatly lower the car. i don't really care if it seems 'retarded' to you, aslong as its safe. since if you think about it. its essentialy the same as lowering blocks in the rear. it just re positions the wheel in relation to the spring. Now that was a serious question. is it a safety hazard? i cant take pics if needed Quote Link to comment Share on other sites More sharing options...

bubblegoose Posted August 5, 2010 Share Posted August 5, 2010 id feel way more comfortable cutting half a coil out of the springs, if the shocks have been shortened already then they should still be captive. (guessing here as i dont know how they bolt up exactly)adding washers will (without trying to be all brocklee and using engineering terms) increase the leverage the strut has on the bolt making it more likely to snap Quote Link to comment Share on other sites More sharing options...

Another idea i have had. is ive got the factory rear springs from my sw20 mr2. they look to be the same diameter but should be way stiffer. might look at trimming those to the height i want so it will be stiffer and less likely to guard rub. btw. mr2s spring style is swapped around due to MR config (skinny spring at back, fat at front) Quote Link to comment Share on other sites More sharing options...
UTERUS Posted August 5, 2010 Share Posted August 5, 2010 btw. mr2s spring style is swapped around due to MR config (skinny spring at back, fat at front) Are you saying that fr and ff cars have stiffer rear springs than the front? If you are, that is not correct. Quote Link to comment Share on other sites More sharing options...
