Spacing between postbits

[SpeedStreet]

Like normal, I'ver used the following code tags to split up the space between my postbits. However, The spacing seems to be different between the first two posts and the rest. Also, the purple background seems to retain itself behind only those first two posts and drops off after that.

Any reason behind this?


End of my postbit attached:

 
<tr>
<td>
<br />

</td>
