thanks for this informed post ,what do you guys make of this ? with my homemade caltracks i have set up in my crapa is lower hole shocks on 1, 0 pre load is the only way this will hook 2inch lowed blocks ,split mono leaf ,calvert 90/10 my 60 ft are 1.6 ,will it work better with a small air gap , with pre load it spins.

---

Do you ever video your launch... if your rear shocks
are set on 1 try increasing the stiffness... you
could be running out of travel... make SURE your
front end can move freely and has 5" of travel

Bottom hole – Softer Hit, moves IC forward

---

how does being on the bottom hole on the caltracs change IC ?

---

The bar is lower(more level) and moves the intersection point futher forward.

I can see 2 things ... first you need to add some
pre-load to the right bar... your car turned to the
right at the hit and the front doesnt move much

thanks it has 4 3/4 inch travel in front and i did try pre load in the right next time out and it tosted the tyres and i back it of and hooked better again , i have calvert 90/10 they seem to easy and may not be holding the car up ,what do you think

---

Then take pre load out of the left bar

Have you had the car on scales... your weights could
be way out of wack

I thought the IC would only change from the front spring eye hanger being moved up or down on those holes not the bars...

What's funny is; Calvert's site USED to say that they changed the IC......Then they changed it to where it didn't mention anything about changing the IC.........and now there is absolutely NO instructions or info on the site about how they work...... ......and typically NONE of the people that post about them can answer that and I've never seen anyone that says "they move the IC forward" be able to draw a picture showing exactly where the IC is moved to...

IMHO, they don't change the IC..... ALL they do is stiffen the front spring half (after all, they are just mono springs)...... With a larger gap or the bars in the bottom holes, it takes more spring wrap up before they stiffen the front spring half, allowing the pinion to climb the ring gear and stick the tire or wheel stand......
