These are derived from tests, professional drivers and chassis engineers.<\/p>\n<p>You should always consider driver, fuel, and cargo weights when your Corvette is aligned. Please note that these specs are symmetrical. For examples, when we recommend 1\/8\u2033 toe in, that indicates 1\/16\u2033 on each front wheel for a total of 1\/8\u2033 total toe in.<\/p>\n<p><strong>Daily Driver<\/strong>\u00a0\u2013 These specs are designed to minimize tire wear and dynamic forces on front end parts. Driver effort is minimum, the car will steer very \u201clight\u201d and may wander or be \u201cdarty\u201d on road with wear ruts. If you are uncomfortable with this feelings, toe the car in up to a maximum of 1\/8\u2033 total toe in.<\/p>\n<p><strong>Advanced Street<\/strong>\u00a0\u2013 These specs are designed to give an even quicker steering response with minimum tire wear. If the car is \u201cdarty,\u201d toe the car in. By toeing in, you may lose some turn-in qualities gained by the initial specs.<\/p>\n<p><strong>Autocross<\/strong>\u00a0\u2013 These specs are a good baseline to start from. The driver must take into consideration the size, compound, and condition of the tires. The chassis is affected by the valve package in the shocks, spring rates, and sway bars. The Autocross course design and the condition of the surface will also have a bearing. These specs do not work and are not recommended for street use because of adverse tire wear. The car will act \u201cnervous\u201d when ever changing street surface.<\/p>\n<p><strong>Track<\/strong>\u00a0\u2013 These specs are by far just a baseline. Those of you who race know alignment specs will change based upon weather, track, and unique setup. These specs can also change on each corner of the car and driver to driver.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Chevrolet recommended alignment settings:<\/strong><br \/>\nFront (with power steering)<br \/>\n<strong>*<\/strong>Caster +2 \u00bc degrees +\/- \u00bd degree<br \/>\n<strong>*<\/strong>Camber +3\/4 degree +\/- \u00bd degree<br \/>\nToe-in (total) 3\/16\u201d to 5\/16\u201d<\/p>\n<p><strong>*<\/strong> Must be within \u00bd degree of opposite side.<\/p>\n<p><strong>Caster &amp; Camber Information<\/strong><br \/>\nIncreasing the number of rear shims in relation to the front increases caster. If static camber is already correct, generally speaking you&#8217;ll need to split the difference to increase caster by adding about half as much shim at the rear while removing that approximate amount at the front. However, the ratio isn&#8217;t linear as the CA shaft rotates further from parallel with the chassis, and you want the upper ball joint&#8217;s distance from chassis CL as seen from above to remain constant to maintain a given static camber. Uneven caster will pull to the side with less.<\/p>\n<p>If caster is already correct, pretty much add or subtract the same amount of shim front and rear to adjust camber.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-full wp-image-1170\" src=\"http:\/\/www.apatco.com\/corvette\/wp-content\/uploads\/2016\/09\/caster_camber.jpg\" alt=\"caster_camber\" width=\"800\" height=\"389\" srcset=\"https:\/\/www.apatco.com\/corvette\/wp-content\/uploads\/2016\/09\/caster_camber.jpg 800w, https:\/\/www.apatco.com\/corvette\/wp-content\/uploads\/2016\/09\/caster_camber-300x146.jpg 300w, https:\/\/www.apatco.com\/corvette\/wp-content\/uploads\/2016\/09\/caster_camber-768x373.jpg 768w, https:\/\/www.apatco.com\/corvette\/wp-content\/uploads\/2016\/09\/caster_camber-500x243.jpg 500w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Front 63-82 Corvette Daily Driver Advanced Street Autocross Baseline Track Baseline Toe 1\/32\u2033 0\u2033 3\/16\u2033 out 0-1\/16\u2033 out Camber 0\u00b0 neg .25\u00b0 neg 1.5-2\u00b0 neg 1-2\u00b0 neg Caster 2.75\u00b0 pos 2.75\u00b0 pos 2.75\u00b0 pos 2.75\u00b0 pos Caster (With Offset A-Arms) <span class=\"excerpt-dots\">&hellip;<\/span> <a class=\"more-link\" href=\"https:\/\/www.apatco.com\/corvette\/?page_id=1166\"><span class=\"more-msg\">Continue reading &rarr;<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-1166","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/www.apatco.com\/corvette\/index.php?rest_route=\/wp\/v2\/pages\/1166","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.apatco.com\/corvette\/index.php?rest_route=\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.apatco.com\/corvette\/index.php?rest_route=\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.apatco.com\/corvette\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.apatco.com\/corvette\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=1166"}],"version-history":[{"count":6,"href":"https:\/\/www.apatco.com\/corvette\/index.php?rest_route=\/wp\/v2\/pages\/1166\/revisions"}],"predecessor-version":[{"id":1342,"href":"https:\/\/www.apatco.com\/corvette\/index.php?rest_route=\/wp\/v2\/pages\/1166\/revisions\/1342"}],"wp:attachment":[{"href":"https:\/\/www.apatco.com\/corvette\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=1166"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
