Thanks. The Murfdogg 1s 13.5 is really good...fast. My LRP 13.5 is fast as well. I'll be trying the Ballistic 13.5 next. My rollout at the track I posted above is about 88mm (41.25mm/72t/49t). We run without boost at this time. The really guys fast turn fast laps of 9.8-.9; my fast laps are 10.1's. I just have to keep playing

Jason, part number DB6488 8-32 X 1/4 screws are about twice as long as the screws that came with the kit. Are we supposed to cut these? They may fit the rear mount but, the front is too long and will hit the arm.

?

I just placed an order last night, order number 734. Would it be possible to get a set of those added to my order?

Jason, still looking for confirmation on this:

A set screw now will go into the pivot ball, the standoff threads onto the set screw and then you hold the hinge pin block on by threading the 2 4-40 screws into the standoffs. I figured it would be a nice option for those who want to shim high without stacking a bunch of shims. The new standoff kit will include the standoffs,2 4-40 x 5/16 set screws and 2 4-40 x 1/4 flathead screws. I will get them on the website today or tomorrow.
Getting my order set up online, is this the part number for the standoff kit? CH1070

don't worry, the picture is not right, but it is the item you are after.

I'm trying to understand the effects of moving the shock positions forward and back. I tried searching and the above quote is all I came up with. Now I understand how it effects rear traction but how does it effect steering?

Basically I'm building a mod car for the winter season here in Minnesota. I'm trying to figure out a good starting point. I have been very competitive in stock. I run my shock all the way forward because it feels smooth but I find myself running lilac and 2x pink to get enough steering. Is this normal or what do you recommend?

Thanks in advance.
