Default Third member with IS300 Torsen LSD

Just got a used IS300 Torsen LSD installed with 4.1:1 FD. I would like to thank Jeff Lange for answering all the questions I had while shopping around for the components.

Took me a few weeks to get the right diff unit because the eBay seller sent me the wrong one first, and they had to check their inventory for the correct one.

The new gear set I ordered from Spencer at Weir Performance. I picked up the whole diff rebuild kit since I would be getting the diff set up with new gearing.

Paul at Lextech did the install and set up the diff for a really reasonable price.

Feels great and acceleration improved just a bit. Noticeable enough, but didn't impact mpg too much. Plan is to break it in his week, and then take it to the track this Sunday. Didn't take any pictures of the process, but you can check the other two threads by Jeff Lange and B16da9.

Nice job!

When you say "track", what kind of racing will this be?

It's just an open track day at Willow Springs in the Streets of Willow track. I will probably be running with other cars in my same performance class.

The LSD drove well. The tires weren't optimal, being stretched. I'm looking to get properly fitting tires when it comes time to replace. I ran in the beginner class, so there were some cars faster and some cars slower. My friends I went with drove e36 M3, 370Z, RX8. I was 4-7 sec slower than the 370z and only 2-3 sec slower than the RX8.

Here are some pics of the outing.
Overall a good day, although my buddy's M3 overheated during the 2nd to last session and it has to get some engine work done to replace a valve.

I know I got to work on my taping skills haha. It kept flying off each run since it was so hot.

Here are some pics snapped after.

Congrats on completing it, do you now find yourself turning off TC before you start driving the car?

This mod won't work on an IS350.

Haha yeah, it's become a daily affair. It's helping to shorten the time before I get my proper tires though.
