Thumper Posted October 16, 2007 Share Posted October 16, 2007 I will be replacing the front tires soon on my GTO and will get the car realigned when I do. I am looking to get the most high speed stability as possible since this car is too heavy to handle GREAT and I mostly use the car at a drag track/highway. Right now I have .10" toe front, -0.1 camber, and 8.5 of caster in front. .14" toe rear, -1.2" camber rear(not adjustable). Would you change anything or keep it the same? I just got home and found the actual alignment settings. Quote Link to comment Share on other sites More sharing options...
thehelix112 Posted October 16, 2007 Share Posted October 16, 2007 I'm not sure which way toe is measured, but I believe you'd want zero toe/toe in for stability (front and rear). Dave Quote Link to comment Share on other sites More sharing options...
Thumper Posted October 16, 2007 Author Share Posted October 16, 2007 I too at first thought that 0 toe would be best but I then thought that in order to counter any changes in the road it would be best if the tires were fighting each other just alittle to keep tension on the suspension.?

JMortensen Posted October 16, 2007 Share Posted October 16, 2007 Toe in front and rear makes a car more stable. .02 degrees seems a little light on the front end, but I haven't used degrees in a long time. You want something around 1/8" toe in (total). Quote Link to comment Share on other sites More sharing options...
Thumper Posted October 16, 2007 Author Share Posted October 16, 2007 I just found my actual alignment settings and updated the numbers. Also 1/8" equals .010". So I have perfect on front and ever slightly too much on the rear. But on the rear its recommend to be at .020" so I think i'm good there also. Now that i'm looking at the numbers I worried about the little negative camber. I wonder if lets say -.4 or -.5 would be better. Any thoughts?

Zmanco Posted October 16, 2007 Share Posted October 16, 2007 Here's a little spread sheet I made that helps convert between total toe-in in inches and degrees. The conversion is dependent on the diameter of the tire so you can't just use a single value. Thumper, I guessed your front tires are 245/50-18 and if you want a total of 1/16" total toe-in, then the total in degrees would be 0.26 degrees. But enter the actual size to get the actual value.

JMortensen Posted October 16, 2007 Share Posted October 16, 2007 Very cool little spreadsheet. Might put it in the download section as well. Quote Link to comment Share on other sites More sharing options...
Thumper Posted October 18, 2007 Author Share Posted October 18, 2007 So what do you think about the camber settings? Should I add negative camber to the front since the rear has so much? Thanks Quote Link to comment Share on other sites More sharing options...
