Step 2.8: Suspension Overhaul Part 2

When we last left off, there had been some major changes to the rear suspension using off the shelf parts. One of the goals of building this car was to learn more about what it takes to make the 240SX a competitive chassis, and in that process create parts for the up and coming drifting scene in Arkansas. This is a time consuming process to be done correctly! Anyone who whips together parts overnight for your car without obviously having done lots of homework might be selling you a sub par part, you'll see evidence of this later in this post.

First thing first, measure what you've got for a baseline!

Pay attention in school, it comes in handy at the most unexpected times. 
We use precise jigs and tools to create these parts, but subsequently that also means we cannot show you the process we use to make said parts, as it is very intricate work and considered proprietary knowledge. Lets just say magic happened, and two symmetrical steering knuckles with an appropriate level of aggresive steering angles appeared suddenly.





The steering arm is shorter than stock, but not so short that it exceeds the capability of the remaining front suspension and steering setup. Notice the simple guards we use to protect the joint and nut contact points on the knuckle from slag, including the spindle shaft. These knuckles will work perfectly for all types of drivers, and will undergo some very heavy duty testing March 9th at Stick to Drifting: Round 1. This will be held in Mineral Wells, TX on Saturday, so if you live in the area come check us out! If you mention reading this you're sure to get a ride in the car.

During testing I took the old set of knuckles and cut them apart to make some templates, and I was very scared to find this...


 

Beware of sub par parts! There is a serious lack of penetration on some of the welds. This could lead to a failed part and possible crash. We take extensive measures to properly prepare our knuckles before welding to ensure complete penetration. I think the visual quality should be a prime indicator of the effort put forth.



It was a long day of hard work, but who said great things come easy? That's right, no one. Stay tuned, I have plenty more for part 3!
