CAL TRAC PRELOAD QUESTION

Hi,
was racing at the Nats and a guy came up to me and asked how I had my cal tracs set, I have the whole set up, they're mono spring etc. rancho shocks, I'm a 11:00 nostalgia SS car, my car's best is around 1.46 .60ft, most of the time around 1.49 to 1.51, during class run off with similar cars et, I look at others .60ft and mines good if not better than theres. any way the guy said he talked to another racer who's running good and has 2 turns of preload on his bars, and I'm running with about 2 flats on the bars, two full turns seems like a lot. it seams like it would bend the springs quite a bit to get 2 full turns on the bars. just wondering what others use and what works for them. maybe I'm missing something.
thanks
Russ

I got 2 flats on the left....4 flats on the right. Seems to hook the best there. 3700# Challenger with 1.46-1.47 to 1.52-1.53 depending on the track. Hits the tire hard. Ranchos on 8.

i have a 1/4 turn each side,as per a call to Caltracs.
pulls straight,never had cause to try anything else
i have found the ranchos work best for me on #9,1.54-1.57 60

Once you have your side to side set up and done trying different pre loads is part of the tuning you do for your car. what it likes. There is some nhra stockers that put up to 2 full turns of preload after it was set up.

I only run a 1/4 turn on both sides. Bottom hole, shocks on 9.

IIRC, 1/2 p-l on driver side, 1/2 + 1/3 on passenger side, 5-way Ranchos on #3, bottom hole ==> 1.45-1.46 60-fts on 275/60R15 ET Street Radials.

At beech bend, I changed from 2 flats on rt. side to having the pin just touching the spring on both sides with drivers weight in and motor running when setting them. I was 1.44-1.47 with the car "detuned"

This will soften up the hit I assume,,,

Sounds like it varies alot with the individual car,,,

I have heard leave a "nickel" size air gap,,,all the way up to lots of preload...as far as ways to adjust them.

Jake, ( and Jim ) ,,what are you running for rear tire pressure ?

thanks,
