So I have 15x10 in rear with 28x10 Hoosier slicks .. was going to grab some 370z spare tire wheels that are either 17x4 or 18x4 . Now does it matter ? Is one better than other . Also if I go 17x4 is it better to get 26x4.5 or 27x4.5 and same thing with 18s ? Like does the front height matter ?

 

I have to assume this is for a drag race application. I'd check the overall diameter of the 370Z spare tires, as you don't want to have a reverse rake in launching the car.

 

yoy are correct for drag racing , the spare comes in either a 18in or 17in . I’m sorry for my not understanding but what’s reverse rake ?

 

Reverse rake is front sitting higher than rear

 

Correct! you'll want to measure the spare tire/wheel from edge-to-edge and compare it to the overall length of your 15" tire/wheel combo. You don't want to be launching a RWD car without at least a little rake on the car. But I'm a road racer, and it makes me a bit nervous to be using spare tires for fronts anyway.

 

Weight transfer to the power wheels baby!! 🤣
