But with the increased torque and horsepower I&#39;m not sure the stock KP61 rear diff and axle would be able to handle it. So I guess it&#39;ll lead to a rear axle swap as well, but I have a couple of problems I&#39;m not sure how to solve.<br /><br />From what I know the AE86 rear axle is approximately <b>50 ~ 55mm</b> wider than a stock KP61 axle... would that be an issue in terms of wheel width and so on? Is there a way to &#39;shorten&#39; the axle and the housing?... because I haven&#39;t quite heard of people cutting down rear axle housings.... so I don&#39;t quite think that is an option.<br /><br />Or can I just use a different offset wheels to solve this... but then the front tyres will have a problem with the offset won&#39;t they? Or can I just add spacers...? but I&#39;m looking for a solution that doesn&#39;t compromise performance, because as it is I am quite an aggressive driver, hehe <!--emo&:P--><img src='http://static.lowyat.net/style_emoticons/default/tongue.gif' border='0' style='vertical-align:middle' alt='tongue.gif' /><!--endemo--> GBirdie The Fast &amp; The Furious Mon, 07 May 2012 13:50:54 +0800
