And also Customworks has some different center springs!

Will the tc springs work on a threaded ksg center shock, its the blue one?

Yes, the TC3 springs will work on the shock that comes with the KSG kit. They are just shorter. We use them all the time.

How do i make those work.

From the looks of your track the sylva's should get you what you need,start with a copper.

Both Center and Front Spings lists have been added to http://jimsmith.iwarp.com/RCDownLoads.html

And as soon as I find my Side Shock Spring list I will put it there also...
