Got the sliders burned in and after moving the car around the shop, I noticed the springs (split monos) settled and the rear pin position appears to be too far back. According to Calvert, it should be at 75% . When I initially mocked them up before welding in, I had them at 60%. Now they appear to be too far back.

Calvert says it’s fine, but I’m not convinced…. This is at ride height but there isn’t any fuel in the cell so the added weight will push it even further back. Thoughts?

I'd just wait until it's driving so you can see if it bottoms out, then make any adjustment if necessary. No sense in changing anything now in my opinion.

Think that's what I will do. Calvert says if needed, I can shorten up the rear half by drilling a new locating hole on the spring half .75-1" from the existing hole so the fix is easy. Also said it wouldn't affect the spring rate or ride height. Be nice to not have to do anything though.... lol
 
Mine are close to that far back - and i dont have any issues. In fact, I tow a small trailer on drag and drive events and they still do not contact the end of that travel even with the trailer hooked up.

That’s great news! Thank you
 
If they do bang and stuff and it were my car I would bend up a piece the same dimension as the slider box width about 1.5 - 2 inches, weld it on the back side and grind another 1/2 in of slide.

Those are cool. I want some now.
 
When installing sliders I tack them in place until the car is race ready with my weight simulated in the seat. I have also plug welded an axle shim between the slider and frame to fix the working angle.

For the most part we are worried about separation so the current position accomplishes that task. Most rear race shocks are stiff on compression and somewhat or slightly looser on extension. For example, I run the rear QA1's in my GTS (3) clicks from full stiff on extension and at the highest setting for compression.
 
We made them removable and adjustable. The fronts are also height adjustable. Also the leaf spring pin locator on the perch on the right is adjustable front to rear this is to adjust for a straight launch and correct the rear of the car shifting doing a burnout. We wanted to have a totally adjustable leaf rear suspension. The rails in the pictures were moved up into the car 3 inches plus no shackles and 1 inch drop calvert mono leaf springs. This can all be done the same way with the factory rails as we did in the past.
