Sorry I've been MIA lately. Been pretty consumed with moving for my new job.

Here's a quick vid of the new setup.

This was a 20 punch to about 135. Closed roads of course.

Got a few good races in tonight. I beat a 540rwhp c5 Z06 by a couple cars on a 30-140. Hopefully I'll get my buddy to edit the video and put it up soon.

Well I have some news. Not sure if its good or bad.

I took apart my cv axles to replace the boots and found this:



Both ends....

Name:  2012-08-11_12-38-38_468.jpg
Views: 1694
Size:  153.6 KB

This was the passenger side. 275 street tires, on the street.....

This is a custom axle from a z-car vendor. Its 1.3" in diameter, so just a shade bigger than a ford 9" 28 spline.

ALSO, the driver's side axle (stock Z31T) was completely fine. Splines had NO issues on either end......

On the next "unbreakable" solution i guess. It raises some concern as this was ONLY street tires, on the street.

Jmortesen on Hybridz sells a pair of shortened axles for $575. Which vendor did that one come from ?
