If it starts to get unstable, just let off the gas. Too many try to be a hero and stay in it.
Only time I've ever had a high speed issue was w/ bias ply tires that had too little air pressure.
My "first" dedicated drag race car was a 1960 Dodge Phoenix that weighed over 4100 lbs. without me in it, I put a cheater 1959 SS 383 stroker motor (unknown C.I., 4.375 stroke with a 4.410 bore, I think
I didn't have any micrometers back then
) in it. It ran high 12.s at 105 MPH at the old Thermal air port drags in Coachella Valley, CA a long time ago
It had a set of 5.0x14 inch stock steel rims on it with a set of Penny 8.00x14 7 inch wide drag slicks with probably way to little air pressure in them
It would wonder around every time I let off at any speed above 30 MPH, I soon learned that the back had to follow the front as long as I didn't try to correct with the steering wheel
I would put a tiny bit of left turn into the wheel after I let off in the 1/4 mile and let it slow down while the back end sashay around all it wanted to
I've never crashed a car at the track, YET
Not so on street cars
Be safe, don't crash
