BoxsterLS376 introduction - LS3 conversion :)

[BoxsterLS376]

:troll:


Soooo... this morning started out well, it's been pretty nice so I decided to go ahead and drive the Boxster in today... took a back road in and saw about 5 deer grazing, it was great!

Ever since I put my factory axle back on I've been getting a little vibration under acceleration which can't be good. This morning was no different but I persevered anyway. So I was almost to work when I pulled out onto highway 41 second gear and leaned into it around 3K or so once I was going pretty much perfectly straight and moments later BAM!! ********************.

This time it was the drivers side which is still the brand new aftermarket axle... starting to think these aftermarket axles just aren't up to this task. Luckily I was almost done rebuilding my other factory axle so I got a ride to the shop and finished putting it back together, went back and swapped it out in the parking lot I broke down in. What a PITA. It is really not that bad of a job but I'm getting sick and tired of doing it!!!

So needless to say I got it going again and limped it back to the shop where it will stay parked until my Tarrett Engineering axle spacers show up sometime next week. Hopefully that alleviates the problem.

I tell you what shocks the piss outta me is that in my last conversation with Steve @ Renegade when I told him what happened with my first axle he reassured me that they haven't broken any axles except on a track car which had been running for 6+ months. They just run stock axles, no mention of custom anything, spacers, LSD, nothing. I just don't buy it. Does my engine/transmission somehow sit further back then theirs do? I dunno but once I put in these spacers I'm gonna run the piss out of it here on the street in front of my shop so I don't get stuck in a random parking lot again. Hopefully it solves the problem.

The axle geometry was always my biggest concern on this transformation. However all the sand rails I've seen built have more abrupt angles and seem to have no issues but the sand gives a bit unlike pavement and wanting traction. I'm also not surprised that Renegade was not forthcoming on anyone having axle issues but i bet they have them. Hope the Tarret spacers fix the issue.

You sir seem to be correct! I don't believe it to be the angle of the dangle but rather the distance between A and B!


Greetings all!

If you have been following along the you know I've had a few axle issues lately The outer CV joints were getting stressed to much and pulling apart due to the transmission being set back further in the chassis.
I wanted to get longer axles when we came up with the idea to just add spacers! Waaay cheaper and better option, at least for testing purposes, and if they work out fantastic! So I put my idea out here, got some great feedback and found out that the spacers I was going to have custom made already existed!! w00T w00T!!
Thanks again to "The Radium King" for pointing out that Tarett Engineering who are well know for competition level suspension systems already had spacer kits available!!! OUTSTANDING!@!
Axle Spacer Kit, Rear, 15mm, 986 /987/996/997

The spacers are 15mm and their kit comes with the appropriate sized bolts in 12.9 grade!!! Took less then an hour to install and fit perfectly...
Better yet I can already report that this has made a VAST improvement to the overall feel of the car. After installing my recently rebuild factory axle I had been getting some vibration under acceleration which seems to be gone although some longer term testing will need to be done to be sure.
Also gave it the good 1-2 in front of the shop a few times and haven't broken anything yet! I've got a video of that too which won't be publicly posted to youtube just because

Here's a look at the Tarett Engineering Axle kit which has saved the day and hopefully saved me from having to do any more parking lot axle swaps!!!

Video should be done uploading in just a few minutes~
