With the 418 bulkheads being around 2.5mm (not exactly sure about this) higher than the 417 ones, I feel that's even more unusual. That must change the rollcenter dramatically.
So can you tell us what the purpose and the effect of that change over the standard setup was?
Thanks,

So I've found the difference between the shims under the inner ball stud are very crucial on carpet. At 0-1mm on Sweeps I traction roll. 1.5-2.0 the car is very unstable if you hit a dot. At 3-4mm the car becomes very stable and very forgiving. When your in a great setup window a .5mm difference can be huge. So if Sean is running a 4mm shim he may be on high bite carpet.
I don't know Sean's grip level at his track but his setup for our track which is low/medium traction seems a little pushy but very stable. It's a fantastic base setup and highly recommend it as a starting point. As all tracks are different in grip no one setup is perfect but you can take that setup almost any where.
I will finalize my setup this week but it's not all that different. But it does use the stock springs as I didn't want to use anything else at first. I just have a few more things to try till my setup is final. This is a baseline for Sweep 32's for Nats if I can go.
