“Secret” No Prep Suspension Setup / Its a secret!


Here is the way we change our car to go no prep racing. Front side no prep racing is a little different than back side, and today I’m sharing what we do. Taking anti squat away to make it so the tire doesn’t get squashed excessively is important. Next 3 weekends of racing, we will be going front side, so the suspension should stay the same until Dig or Die the end of March.

  1. Great information John! Curious if you plan to take some angle out of the rear wing? Obviously you don’t need as much downforce for front side plus it could flow down your trap speed and/or make the car more prone to wheelie. Good luck John!

  2. Do you like the narrower track width in the back relative to your old car? I guess the shorter the axle, the stronger? I really liked how your old car's rear track with looked, but I am don't understand the benefits of narrower/wider track width.

  3. So wait you’re proving a old point the 28×10.5 the 10.5 is the width. I’ve known that for selling tires for 26 years. But most think a 29 is the width. Thank you for clarifying the second number is the width. Say it louder for folks in the back.

  4. Ok John, I need some feedback… Racing a No prep in California this weekend…. First 80 feet is new concrete with 1 small event on it. The rest is new asphalt… So I have a 93 Coupe, 421LS, 94MM turbo, 28" M/T, Glide (4.7 car on radials) I ran alot of Antisquat before * Now my new Baseline suspension settings come back at 68.69" IC/Instant center height is 12.86" and Antisquat is 94.54% Am I in a starting ballpark? Thank you in advance! Car has been on Radial prep for the last
