Bart....I like your Pro Tinkering approach. I'm all for doing what you can, when you can without downing the car for to long. Hey...that's the reason we buy these things is to enjoy them!
The small projects you're doing now are a great way to get to know the car and will pay off huge down the road. That and it gives you something to do.
There are so many options when it comes to suspension and drive terrain. Take your time and if able get out to a few event and bum a few rides around an autocross track. Great way to find what's right for you and have fun.
Thanks for sharing! I'm looking forward to seeing more.
