20" drag radials

[rod7515]

My friend bought a 2015 challenger scat pack this summer and has taken it to the drags twice so far. His problem is that the car doesnt hook. He has 20" wheels and is going to buy after market rims so he can mount drag radials. Summit only carries 3 nittos to choose from. Was wondering if anyone else has tried these and if there are other choices that would hook better? Thanks for any help you can send this way.

Step the rim size down to 17" so there is more sidewall flex.

I agree with Woods74 I have a friend with a Scat Pack Charger he tried Nitto 20" and still had a hard time hooking up at the line so he went to 17" and got his 60ft down to 1.8 Now he has a great time with it.
