<div dir="ltr" data-setdir="false">Excellent feedback....thank you Larry....think we are hitting on the real issue which is alignment settings. What I noticed with the added 6 or 7 degrees of caster was the Pantera LOVED the sweeper turns at speed like it did the long straight-aways but it did NOT like the long straight aways....so clearly this is alignment settings.</div><div><br></div>

I get 4-4-1/2 degrees with offset bushings and shaved upper Ball joints. Modified or Aluminum A-Arms should give you up to 8 degrees, I’d try 6 degrees and make sure the steering wheel doesn’t want to cut your hands off at the wrist after making a turn. More caster will make the Pantera more stable at speed, too much will be a handful when turning.</p><p class="ydp2c4327f8yiv3879782719MsoNormal"> </p><div><p class="ydp2c4327f8yiv3879782719MsoNormal"><span style="font-size:9.0pt;color:black;">Larry Stock</span></p></div><p class="ydp2c4327f8yiv3879782719MsoNormal"><span style="font-size:10.5pt;font-family:sans-serif;color:black;"><br clear="none"></span><span style="font-size:9.0pt;color:black;">Pantera Parts Connection LC</span><span style="font-size:10.5pt;font-family:sans-serif;color:black;"><br clear="none"></span><span style="font-size:9.0pt;color:black;">550 Mallory Way</span><span style="font-size:10.5pt;font-family:sans-serif;color:black;"><br clear="none"></span><span style="font-size:9.0pt;color:black;">Carson City NV 89701</span><span style="font-size:10.5pt;color:black;"></span></p><p class="ydp2c4327f8yiv3879782719MsoNormal"><span style="font-size:9.0pt;color:black;"><br clear="none"></span><span style="font-size:9.0pt;font-family:sans-serif;color:black;">www.PanteraParts.com</span><span style="font-size:10.5pt;color:black;"><br clear="none"></span><span style="font-size:9.0pt;font-family:sans-serif;color:black;">PH 775-283-4411</span><span style="font-size:10.5pt;color:black;"><br clear="none"></span><span style="font-size:9.0pt;font-family:sans-serif;color:black;">Fax 775-283-4410</span><span style="font-size:10.5pt;color:black;"><br clear="none"></span><span style="font-size:9.0pt;font-family:sans-serif;color:black;">Cell 1-800-DeTomaso 800-338-6627</span></p><p class="ydp2c4327f8yiv3879782719MsoNormal"> </p><p class="ydp2c4327f8yiv3879782719MsoNormal"> </p><div id="ydp2c4327f8yiv3879782719yqt72163" class="ydp2c4327f8yiv3879782719yqt8151197195"><div style="border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in;"><p class="ydp2c4327f8yiv3879782719MsoNormal"><b><span style="font-size:12.0pt;color:black;">From: </span></b><span style="font-size:12.0pt;color:black;">TPR <tpr-bounces@teampanteraracing.com> on behalf of Owen Lee Green via TPR <tpr@teampanteraracing.com><br clear="none"><b>Reply-To: </b>Owen Lee Green <oneeyez4263@gmail.com><br clear="none"><b>Date: </b>Monday, September 23, 2024 at 12:41 PM<br clear="none"><b>To: </b>Mad Dog Antenucci <teampantera@yahoo.com><br clear="none"><b>Cc: </b>Team Racing <tpr@teampanteraracing.com>, Jim Wallace <j.wallace@boston-group.com>, Patrick Mical <pmical@patsauto.com><br clear="none"><b>Subject: </b>Re: [TPR] Pantera Alignment</span></p></div><div><p class="ydp2c4327f8yiv3879782719MsoNormal"> </p></div><p>Slightly softer spring rate in the front might help.

I only average 134 this year and not sure I would have wanted to handle much more then 140 comfortably.....that sweet spot for me....a 140-150 Average....but again something is off.</span></p></div><div><p class="ydp2c4327f8yiv3879782719MsoNormal"><span style="font-size:12.0pt;"> </span></p></div><div><p class="ydp2c4327f8yiv3879782719MsoNormal"><span style="font-size:12.0pt;">Others suggested the wheels might have been off but they were so well balanced from the factory only one wheel needed a corrected weight. Much better then I ever saw with other vendors wheels.
