Trying to launch hard on MT DRs. Blowing away at 18 psi tire press and 10psi boost. 275/60/15s
How much lower can I go?

What did you have the bags set on? I have a similar rear suspension setup and too much air will make the car basketball bounce after the first squat. One of the best things you do in this situation is to have someone video your launch. You can learn a lot.Tires are less than a year old and I have a line lock, got them pretty hot. I’ve got HR sway bar, airbags,LCA’s Can hook good around 7 to 8 pounds boost but I would like to launch with more
drop the tire pressure down to 10psi and evaluate from there,preload the airbag,25psi in the RT,10psi in the LT.generally speaking the radials will go faster with more psi provided it takes the hit,however on hard hitting combos the radial can be shocked into wheelspin needing the lower pressure to allow the sidewall to work better.it can be overcome with contact patch and power mgmt but the 275/60 is light on contact patch and has the stiffer sidewall.the pro is a much better choice due to the sidewall being softer so its less resistant to wheelspin from initial shockmy best 60ft was 1.53 with a 7-8# launch. Always looking to do better.
