Every car is different, you have to find that sweet spot in every car no matter how fast or slow.
Nick, this discussion nor my comments are about 2500 lb. tube chassis cars which can't be compared to 3500+lb.stock suspension cars nor 3000+ lb. back halved cars. Their "wheelies" as well their wheelie bars are in play for different reasons.

Ed you guys have found the sweet spot with the Firebird. Car leaves flawless every pass, your chevelle was awesome to watch and was consistent. But you had to spend the time with it to find what it wanted, shocks & settings, travel limiters or non, rear suspension settings, etc..

Make 1 small change, keep good notes or read your data acquisition.
Thank you and I do. My Chevelle was badazz but a totally different car than my Firebird. That said, in all honesty I set the Firebird up in the first few outings of buying it back in October of 2008, after installing my engine, trans, converter and rear gear, I changed the ride height, front coilover springs, shock settings, travel limiters and wheelie bar height.

This photo is from my 2nd weekend out in the car in October of 2008 after licensing with the car the week before.



In 2009 I swapped out the front shocks to Afco's bnc shocks and those same shocks are in place today. From then until the winter of 2022, when the front and rear suspensions were rebuilt as a part of updating and freshening this car from front to rear and top to bottom

the car has been run with the same suspension settings other than adjusting the front shock extension on race day. The car as I run it today is about 200 lbs. heavier than when I bought 16 years ago and has far more power under the hood than when it was raced in Super Stock or when I bracket raced it footbraking.
