I was guessing the same thing if weight scaled with how much power it is &quot;supposed&quot; to hold, but I guess it depends on a lot of things.<br /> <br /> I am just theorycrafting if I can shave weight by using scca update/backdate allowances.<br /> <br /> ----<br /> &#039;&#039;&#039;G-E:&#039;&#039;&#039; &lt;small&gt;(2014-06-24 23:51:39)&lt;/small&gt;<br /> <br /> Alex is correct, but the difference isn&#039;t a lot, will you really notice 15lbs in the middle of the car?<br /> <br /> ----<br /> &#039;&#039;&#039;michaelp:&#039;&#039;&#039; &lt;small&gt;(2014-06-25 00:26:11)&lt;/small&gt;<br /> <br /> T5 (90A) is the lightest. Then 71C. Then 30A.<br /> <br /> ----<br /> &#039;&#039;&#039;frostvectron:&#039;&#039;&#039; &lt;small&gt;(2014-06-25 01:56:47)&lt;/small&gt;<br /> <br /> {{Quote|user=G-E|Alex is correct, but the difference isn&#039;t a lot, will you really notice 15lbs in the middle of the car?}}<br /> <br /> Ah, I guess I was hoping that it&#039;d be a big difference.

Any idea by how much?<br /> <br /> ----<br /> &#039;&#039;&#039;Axel kain:&#039;&#039;&#039; &lt;small&gt;(2014-06-25 12:44:00)&lt;/small&gt;<br /> <br /> I&#039;ll try to remember to throw my spare T-5 on a scale some time! haha.<br /> <br /> ----<br /> &#039;&#039;&#039;frostvectron:&#039;&#039;&#039; &lt;small&gt;(2014-07-25 05:49:58)&lt;/small&gt;<br /> <br /> Well I&#039;ll be damned, just found the info in an old thread:<br /> <br /> http://z31performance.com/showthread…ission-weights<br /> <br /> Guess I&#039;ll keep the 71C then.<br /> <br /> ----<br /> &#039;&#039;&#039;Axel kain:&#039;&#039;&#039; &lt;small&gt;(2014-07-25 12:14:23)&lt;/small&gt;<br /> <br /> I&#039;d wonder about the Z32&#039;s 30A, considering it&#039;s a bit shorter…</div> z31p_Frostvectron
