Wheels for Meh Z

[Malacath]

I am buying wheels for my 1986 300zx, and i came across a set of stern st8 for a good price and the right offset for my car, which is amazing considering my car is horrible to find such a offset for a good price. Anywho they are 18x8.5 5x114.3 +20, i am vary worried about a perfomance loss with these wheels, stock my car calls for 15s and some years have 16s and there non turbo. How much power would i lose? would it be noticeable, if so were would i loose it at, im curious about the weight of one wheel also...cant find it. i originally wanted 16s or 17s for my car but i took it to a shop and 18s just look so nice on it and fill the massive wheel well. budget FTL :(

Any help is apperciated, thanks :D

You wouldn't actually lose any power. You might feel the weight of the wheels, but it isn't anything life changing. I went from 16s on an older car of mine to 18s. Yes, I did feel the difference before and after installing the wheels, but it wasn't so bad that I wanted to take them off of the car.

If you are that concerned about performance, I wouldn't roll with 18s on the car. This is possibly one of those debates of form v function.
