Nice to see that there are other fans of the JS.

I found this to be a problem as well and I did all I could to stiffen the front end with alum. upgrades but it seemed like no matter what I did the slop comes mainly from the servo saver or the ball cups that gets worn quite easily.

The idea of the front and rear sub chassis is nice but it really didn't work so well. The problem was that the sub chassis pieces were made of the same ABS plastic as the main chassis and when the sub chassis breaks on occaision, it sometimes break the tabs on the main chassis where the sub chassis attaches to. In this case, I'd rather have a one piece durable and solid graphite slab as a chassis like the FS and RS.
The irony about the JS is that after upgrading the crap out of that chassis with all the alum. upgrades, I found that it ran better when it was completely stock with all the plastic pieces.
Go figure.
However, I think that the beauty of the JS is that it was a very forgiving car with lots of flex and to try and stiffen it with alum. upgrades doesn't work. The only way to improve on a JS is to just upgrade to an FS or RS.
