Black Jade 43 Report post Posted April 24, 2019 What alignment specs would be a good suggestion for my setup? 69 Fastback Power steering 1" lowering springs (no shelby drop) 245/45/17 Tires 17 x 8 AR500 wheels 4.75 backspace Had some upper ball joint issues and put new Moog ones in, way tighter than what I had. Thanks, Ed Quote Share this post Link to post Share on other sites
aslanefe 333 Report post Posted April 24, 2019 For street -0.5 camber, max + caster you can get (I am running +8.8 caster at the moment with my modified upper control arms, but with stock control arms and strut rods you can get about +3.5 caster) and 1/16 to 1/8 toe in. No more than 0.25 degrees difference between right side and left side on camber and caster. 1 RPM reacted to this Quote Share this post Link to post Share on other sites

Is tramlining reduced? Isn't it heavy to steer at low speed? Quote Share this post Link to post Share on other sites

Isn't it heavy to steer at low speed? More caster makes the car turn (handle) better. I've read that the closer you get your caster to the SAI (steering axis inclination) the better the car will handle. I believe our Mustangs have 10° sai. I've got 8° caster with manual steering and 245/40-18 tires up front. Low speed parking is the only time extra effort is required by my 63 year old arms. Yes, more caster will result in the car wanting to go straighter. Quote Share this post Link to post Share on other sites
barnett468 418 Report post Posted April 28, 2019 if you run less than 1/8" toe in with stock steering and suspension parts, your tires may be toed out when driving at higher speeds. at least 1/4" is a safer bet. Quote Share this post Link to post Share on other sites
