But yea ^^ ur right 18-20 psi is what we usually do at the track too.<br /> <br /> <small>[ 2014-09-12, 07:35 AM: Message edited by: 90GT510 ]</small> <br /> </font> </td></tr> <tr bgcolor="#dedfdf"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>Stangs R Us</b> <br /><small>Member # 4495</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2014,8,12,10,20,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> It really depends on the tire , get a pair of cheap rims and some drag radials BFG or MT and you can still run them on the street.
