nb6179505 Posted October 22, 2014 Report Share Posted October 22, 2014 Alright guys, came back to Dastun from a 1974 toyota te27 that had leafs. Trying to lower it a bit so theres no wheel gap. I know that too low will cause postive camber. The car is a 71 4 door, I believe at one point it belonged to Datsloco because of the banner. Springs look like d50 springs, up front I have shortened 280zx struts. My questions is... Do I need to lower the subframe to gain access to the rear springs? Or do I need to disconnect the hub from the differential? I took the shock off and lowered the arm but its not enough travel to take the rear springs. Thanks for the help guys Quote Link to comment
banzai510(hainz) Posted October 22, 2014 Report Share Posted October 22, 2014 your disconnect the half shaft near the wheel? I usually put a jack under the drum then lower it when the half shafft bolts are off.of coarse remove the lower shock mount bolt so it drops. you going to cut a coil off the d50 spring? 1 Quote Link to comment
datzenmike Posted October 22, 2014 Report Share Posted October 22, 2014 The spring may already be cut. Cutting is a poor way to lower as it also increases the spring rate... maybe too stiff. There is an excellent article in the Dime Quarterly (Google Docs) for trimming the D-50 front coil to fit the 510 rear. Includes the aproximate drop and spring rate expected. You may find that the spring rate you like is too low... so just add spacers to raise the car. Read it. Quote Link to comment
nb6179505 Posted October 22, 2014 Author Report Share Posted October 22, 2014 Right I know, I just need to know how to get the spring out. t3 Coilovers are going to be ordered eventually. I just was hoping for a short term fix to see the stance by cutting the springs. So go ahead and disconnect the half shaft from the hub? I was hoping this wasn't the case because the bolts are difficult to get to Quote Link to comment
Uber Deaf One Posted October 22, 2014 Report Share Posted October 22, 2014 Sometimes I'm able to just disconnect the lower shock mount and pry the springs out... it's a lot easier to drop the hub-side of the halfshafts though. 2 Quote Link to comment
7string Posted November 5, 2014 Report Share Posted November 5, 2014 If the D-50 springs are un-cut you will most likely have to un-bolt the half-shafts to get the springs out. Use box end wrenchs on the bolts after soaking with PB blaster. With the car out of gear you can keep turning the half-shafts to get better access to the bolts as you are removing them. Also, the E-brake needs to be disconnected at the rear wheels. I find the rear of the car has to be jacked up pretty high to get the control arm down far enough to get the spring out.

Thanks for the help guys Lowering to much creates negative camber and toe in not positive camber. Yes disconnect the shock and half shaft from swing arm you could also loosen the swing arms bolts at the crossmember making it easier to drop. You'll may still need to get a long bar on the swing arm to get it lower and unless that spring has been cut it can still be a bear to remove. Be careful of the stored energy in the spring while removing as it can pop out and rearrange your arithmetic. Quote Link to comment
