gnosez Posted January 3, 2009 Share Posted January 3, 2009 Before refreshing my suspension and adding a set of Arizona Z Car's billet rear control arms I put my 1972 240Z on the scales to get a quick picture of where the car was before I dismantled it. The values shown include my weight, a 7/8 tank of gas, full interior, spare tire, tool bag and the usual spare parts, gnose, L28 NA, 82 5-spd, and quaife R200 w/300ZXT CVs and BBS wheels. Total weight - 2688 LF - 653 RF - 640 LR - 707 RR - 689 Left - 1359 (50.6%) Right - 1329 (49.4%) Front - 1292 (48.1%) Rear - 1396 (51.9%) Cross - 1348 (50.1%) Bite - 20 This seems to me to be pretty good and I was more inclined to think it was not this well balanced before I saw the actual numbers. Has someone found a better corner balancing set-up for both street and track usage (with coil-overs and scales this isn't hard to change)?

tube80z Posted January 3, 2009 Share Posted January 3, 2009 I use the process documented here, http://farnorthracing.com/autocross_secrets11.html and entering in your weights it looks like your about as close as can be expected.

gnosez Posted January 5, 2009 Author Share Posted January 5, 2009 I ran the program and it says I have the car set right. Now the question is this the right set-up for a Z being driven aggressively. I guess I'll have to wait until April when the snow and salt are gone to find out. Quote Link to comment Share on other sites More sharing options...
260DET Posted January 5, 2009 Share Posted January 5, 2009 Depends whart you are doing with the car, sometimes its an advantage to have a particular weight bias for a road course. For street use its not very important within reason. Quote Link to comment Share on other sites More sharing options...
gnosez Posted January 6, 2009 Author Share Posted January 6, 2009 Ah, my point exactly. Now which changes to weight distribution provide what specific advantage for a particular track lay-out? For example, Mid-Ohio is primarily a track with lots of off-camber corners, then there are courses with no banking whatsoever, and then there are those with lots of banking (positive). Which direction does one take with a vehicles corner balancing? Quote Link to comment Share on other sites More sharing options...
Mayolives Posted January 7, 2009 Share Posted January 7, 2009 John C and others with knowledge.............Please ad your thoughts on the subject of corner balancing for road course z cars. Quote Link to comment Share on other sites More sharing options...
260DET Posted January 7, 2009 Share Posted January 7, 2009 I do clockwise circuits so the present setup which has more weight on the two right side wheels suits. Looked at making some changes but the effect diagonally (wedge) was contra to what was hoped to be achieved so it was left as was. But yeh, others will actually have redistributed weight for various road courses so their experience will be invaluable. Quote Link to comment Share on other sites More sharing options...
