A lot of improvement over leafs or caltracs would mean those two types of set ups were not very optimized if the car is slower than about 11.00, and caltracs should be good at better ETs than that. But I definitely recommend going to ladderbars over either. They will work well for you down into the eights. They are the lightest of the three I believe. Also very easy to adjust. I run ladder bars and at 8.90s can run several passes in a row with 60 fts all within .005.




Couple of facts about the current car from this past year.
3670 lbs 46.5% rear weight. (no weight in trunk)
Caltracs running .05 gap. Rancho shocks work best at 3-5. Have to hit the tire HARD
Front end travel is 5.5 inches and it’s very loose.
30x9 Hoosier DO5 slick on an 8” rim. Have 1/4-3/8 clearance each side before rubbing. Tire psi works best at 12.5 no tubes.
505 cubes, 640 roller .272 @ .050 with Rick Allison cross ram
Low gear set with 4.10 gears.
On a new good tire it 60 foots 1.44 /1.47 – that goes away after about 35 runs
Car runs 10.5’s
Work all season on wheel spin and the RacePak still shows an excessive amount.
