I have a g35 with Intake and exhaust, and Automatic transmission modded for fast gear shifts (I dont remember the name of that mod) .
But I have 20" rims, how much can hurt that size of wheels to my time in 1/4 mile?

I'm preparing to start to run at a drag track soon

Thanks!!

 

Now that you got your answer, what is your plans

 

By now just keep the rims and run a couple of times...then with a official time, I can take a decision, maybe keep the rims and mod the engine more, or downgrade to 18
But I need to have at least a base to start

 

The tire is Huge too
275/45/r20 at rear
Front is 245/35/r20

 

Just get some cheap altima 16" wheels with some sticky badda$$ tires on them for the back when you wanna go to the strip. Then get some skinny **** 14" sentra wheels for the front (same lug pattern?). Use yer 20s for cruisin.

 

You shouldn't be wearing 275 45 20's on the rear. Your tire size should be a 245 35 20 for the front and 275 30 20's on the rear. For the track I'd find some factory 19 inch rays and run some 245 35 19's for the front and 255 35 19's on the rear.

 

Sorry, I mean 40
45 is too much

I change to 40 because the car is sitting too low that all speed bump scratch my greddy exhaust...so when i put the 40 size, the car is a little higher and the problem dissapear

 

But, a 40 series tire is still too tall on our cars. I'd install a 285 30 on the rear or raise the car a little.

 

I run 245 40 19s on my sedan looks perfect. Now on a coupe....



Might be goin' for the Donk look LOL

 

Now I can write HOSSIER with white paint on the tire and add 75WHP....LOL
