I was running my stock rear springs (86 SS Monte Carlo) with Koni 50/50's on the rear,and Lakewood 90/10's on the front.The front end has Moroso SBC trick springs.Got a few 1.47's on motor with the car at the end of last year.Its a iron headed 498,car weighs just shy of 3800lbs with me in it.Ok,my buddy let me try his rear springs,his 50/50 shocks,and his 3 way adjustable front shocks.This is my first time back out with the car this year.His rear springs are 12 inch 200lb coil over springs.The rear shocks are 50/50 & his front 3 way shocks are set at 70/30.Took the car to the track wednesday night & it cut 1.60,1.65,and a 1.59 60ft.Are the front shocks too tight?Are the rear springs too stiff?Trying to figure out where I messed up.The motor makes 670HP at the fly wheel,4.10 gears,turbo 400 foot braking it,13.5x30 ET Streets on it right now....have ran 11.5x29 Hoosiers & 315-60 Hoosier drag radial,all low 1.50's,and even a few 1.47's with the drag radials.Tried a different tire the 13.5x30 because my drag radials are done & I had the ET's here.
Tried 15 lbs in the tires & finally last motor pass had 18lbs in them & it hooked best.
The rims are too narrow this I know,they are 15x8's,but I've used them for 3 years now,so it's less tire contact on the ground,but they are what I own so they'll do for now.
Any ideas??Go back to my stock rear springs?Loosen up the front?
pay no attention to the spray pass,that was my "fun" pass.
