Chaparral2f Posted December 23, 2003 Share Posted December 23, 2003 If I lower the rack on my Z31 avbout a half inch will it adversley affect the bump steer? If so, how much? I may need to reposition it to gain oil pan clearance, and I dont want to cause a major steering problem. joe Quote Link to comment Share on other sites More sharing options...
JMortensen Posted December 23, 2003 Share Posted December 23, 2003 Raising or lowering the rack WILL affect bumpsteer. It will probably make it worse, but I'm not positive. You would really have to measure it to see what change it is going to make, or see what 300ZX racers do to fix bumpsteer. If they use a spacer like the early Z's, then you'll make it worse. If they use rack spacers to raise the rack, then you'll make it worse. Jon Quote Link to comment Share on other sites More sharing options...
Chaparral2f Posted December 23, 2003 Author Share Posted December 23, 2003 Thanks Jon, I assumed that it would make it worse, and wonder how much. I may need a little more space under the oil pan because I really don't want to rebuild the motor mounts that I just fabricated. joe Quote Link to comment Share on other sites More sharing options...
datsunlover Posted December 23, 2003 Share Posted December 23, 2003 How about cutting a slot and then weling a 'notch' in the oil pan, enough for clearance of the rack? A friend of mine has done this several times to fit v8's in 4x4 blazers/s10's ect. It that case, it's for front drive shaft/axle clearance, but it's the same idea. You may need to relocate the oil pickup slightly, but it's do-able.. and you only loose a small amount of oil capacity. Quote Link to comment Share on other sites More sharing options...
