As promised, here is the information provided to us. This is a copy/paste so please don't message me if you disagree with the information provided here:
Here is our baseline 470 set up.
- Target hot Tire pressure 18psi front and rear. All of our set up numbers are done with this pressure. I tune the car to maintain the same target hot temp. I have never had to stager my hot temp to make the car work.
- Set up with 10 gallons of fuel and a total car weight of 1410 lbs
Ride height:
- Front 1.875”
- Rear 2.750”
Caster
- Front 5.0-5.5
Camber
- Front -.8 (neg)
- Rear +.4 (pos)
Toe
- Front 3mm toe out each side 6mm total
- Rear 0
Springs
- Front 750 lbs
- Rear 500 lbs
Compression
- Front 7 (from soft)
- Rear 5 (from soft)
Rebound
- Front 6 (from soft)
- Rear 4 (from soft)
Bump Rubbers
- Front Short
- Rear Tall
Packers
- Front 0
- Rear as many as it takes to have .375 - .500 gap between bump rubber and packer at static. You will need a shorter gap for your slower drivers
Shock perch heights
- Front +/- .125
- Rear +/- .250
Corner weights
- Front +/- 5 lbs
- Rear +/- 10 lbs
ARB
- Front Full soft
- Rear baseline at 3” with Sticker tires (adjust for wear)
Wing
- We measure without including the wicker. We start with the front and rear at the same angle. Ranging from 6 – 10 degrees depending on track
Wicker
- Front Tall (.750)
- Rear Short (.375)
- We ALWAYS run wickers. Even the winning car at Daytona ran wickers. The only difference is we ran .375 front and rear.
The primary changes we make are:
1) Rake
2) Camber based on tire temps. (I like to stay within 5-10 degrees across the tire hottest temp in the inside shoulder)
3) Packers
4) Bar (mostly to chase tire wear) (Soften bar as tires get older and start to get looser)
5) Shocks
6) Wing (for tuning corners above 70 mph)
7) Toe
8) Caster
9) Bump steer.
10) Always make sure to keep an eye on tire temps to adjust cambers.
In that order. Very rarely do I have to get passed step 6. Steps 1-3 will usually do the trick for overall handling. Steps 4-6 is for balance, and tire wear. Steps 7-10 is very rarely needed assuming the baseline is correct.
This info is also assuming the car has been Squared and bump steer is correct. Also that there are no excessively worn parts on the car suck as himes, uprights, ackerman plates and blocks, and that the shocks are FM spec, and functioning properly. I suggest double adjustable shocks to be rebuilt every 40 hours, or whenever they weep oil, or loose an excessive amount of air pressure.
