May 18, 200817 yr So I'm thinking about (going to) lower the GSR a little and was hoping for some advice. In the front I was thinking about using brumby front struts with the adjusters on just incase it need to be wound up a little (eg- Making springs captive for inspection) and just cutting a few coils off some spare sets I've got kicking around. And in the back.... Reclocking the torsion bar, What is the procedure for this? How does the plan sound so far?
May 18, 200817 yr the gsr is lower than the 1400 GL Coupe by about 10mms any way. you have to turn the toursen bars round. not sure hows you do that tho?
May 18, 200817 yr Author Yeah thats the plan. Just unsure on how to go about adjusting them and how many spines = how much distance. Thats not as much of an issue though.
May 18, 200817 yr My 1600 service manual states the following in bold; "The vehicle height can be raised by turning the outer end and inner end of the torsion bar by the same number of serration teeth in the opposite direction of the arrow mark on the outer end surface of the torsion bar. Turning the torsion bar in the arrow direction lowers the vehicle height. The changing rate of the vehicle height is 5mm (20 in) per tooth shifted" I assume the 1400 and 1600 rear suspensions would be the same. Hope this helps!
June 3, 200817 yr sweet wagon lowest by law we can go here is 100mm from the lowest point on the chassie or stuctral part i think? normally its 100mm from bottom off the cill
June 3, 200817 yr Author I will have to try and out-do you har har har! Just out of curiosity... Are your springs captive still? Or anywhere near it?
June 3, 200817 yr I will have to try and out-do you har har har!Just out of curiosity... Are your springs captive still? Or anywhere near it? I don't know what captive means but I adapted adjustable coilover sleaves and the lip is from an old Volvo
May 13, 201114 yr Author Dragging up an old thread I know, but I finally got it done. Used '81 Brumby front struts and springs 3 coils cut from springs Struts shortened by 50mm below the spring perch Toyota corolla gas strut inserts (ae92?) Roughly 30mm more removed from struts above the spring perch to get insert captive. And another 20-30mm taken off the shock shaft to get the springs captive. The adjustable spring perches of the 4wd struts mean I can wind the height up to get it above the legal minimum height at inspection time. In the rear I just went down roughly 2 splines. Shocks are for a c22 Nissan Vannette with the ends modified. The front is nice and stiff and responsive, but the rear spring rate is unchanged (read - soft and wobbly in comparison), I was hoping to try and fit Gen1 4wd torsion bars to my 2wd trailing arms in an attempt to stiffen the back up a bit. Does anyone know if this is possible?
May 14, 201114 yr I went 3 splines down on the rears on my FF-1 and its too much, going to have to re-do it Your car looks fantastic. Mine should be riding at a similar height when its done
May 16, 201114 yr I've seen the back end stiffened up with a coil fitted around the shock. Sort of a DIY rear strut assembly. The one I saw looked pretty rude but its not a bad solution assuming the WOF inspector doesn't laugh at you.
May 16, 201114 yr Author Cheers for the nice words guys. Dirk, I think that I might definitely have trouble sliding something like that through a wof, and I'm unsure if theres the room. Clever idea though. Overall it handles fairly well now though once you get it settled into a corner and have your line set.
May 18, 201114 yr Looks the bomb! I lifted the back of my sedan via the torsion bars. Had to get slightly longer shocks to do this. They needed replacing anyway. What a difference a new set of gas shocks make! Maybe stiff gas shocks would help for yours? By the way, If you haven't already, you should look into making a strut tower brace for the front. It makes the car feel so much stiffer. cheers.
May 18, 201114 yr Author Cheers! I fitted new shocks into the back & front at the same time as lowering, They're gas shocks intended for the front of a Nissan Vanette. So are hopefully a little stiffer than what was in there. The shocks that were in there were too long and a Toyota shock, they were bottomed out at that height. Here they are at full droop. Compared to the old shocks I had thought about air adjustable shocks to stiffen things up a bit, and to get the back higher when I have a load/passengers, but I don't think they make anything that short.
May 18, 201114 yr Looks fairly normal but its actually about 100mm higher at the back than it used to be. Ill lift the front about 20mm when I get round to it. Would love new struts for the front but they are very spendy.
May 18, 201114 yr Author Sounds like you need some Brumby/4wd struts. Heres a picture with them in the front of mine before I had the struts shortened. Note - This is Brumby struts, with brumby springs, with 3 coils cut off. I had to cut 50mm out of the strut to get it to a height I wanted.
June 18, 201114 yr sweet looking gsr my dad had one back in the 80"s that we rallied and we did very well keep up the good work with it from a tassie suby lover
